The '''Santa Fe class 3450''' consisted of ten [[4-6-4]] "Hudson" type [[steam locomotive]]s built by the [[Baldwin Locomotive Works]] in [[1927 in rail transport|1927]]. Built as coal-burners, they were later converted to oil-burning during the 1930s. At the same time, the locomotives were given {{convert|79|in|mm|0|adj=on}} [[driving wheel]]s instead of their original {{convert|73|in|mm|0|adj=on}}, and the boiler pressures increased from {{convert|220|to|230|lbf/in2|MPa|2|abbr=on}}. Combined, these changes reduced the starting [[tractive effort]] from {{convert|44250|to|43300|lbf|kN|1|abbr=on}}, but increased the top speed and efficiency. Their early service was in the Midwest, between [[Chicago]] and [[Colorado]]; later, some were assigned to service in the [[San Joaquin Valley]] of [[California]] between [[Bakersfield]] and [[Oakland]].

They were smaller and less powerful locomotives than the later [[ATSF 3460 class|3460 class]] "Hudson" type, but were capable of equivalently high speeds.

The first locomotive built, No. 3450, was donated by the Santa Fe in 1955 to the [[Railway & Locomotive Historical Society]]'s Southern California chapter, and is preserved at the Society's museum in the [[Los Angeles County Fair]] grounds at [[Pomona, California]]. The locomotive sits inside the [[RailGiants Train Museum]]. It is not operational, but preserved in good condition as a static exhibit. It received a cosmetic restoration between 2013-2021.

The '''OA class''' is a solitary [[steam locomotive]] built by the [[Baldwin Locomotive Works]] for the [[Wellington and Manawatu Railway]] (WMR) in [[New Zealand]]. Ordered in 1894, it entered service in August of that year as No. 13 and was the first [[narrow gauge railway|narrow gauge]] [[Vauclain compound]] in the world. In 1908, the WMR and its locomotive fleet were purchased by [[New Zealand Railways Department]] (NZR) and incorporated into the [[Rail transport in New Zealand|national rail network]], and, although No. 13 bore a likeness to members of the [[NZR O class|O class]], it was sufficiently different that it warranted separate classification. The designation of OA was created and it was numbered OA 457. It operated for another two decades until it was withdrawn in December 1929 in [[Auckland]]. The locomotive was known to WMR staff as "The Lady".{{sfn|Palmer|Stewart|1965|p=92}}

In 1896, a locomotive similar in appearance was ordered by the WMR, No. 16. Its technical specifications were such that when it was acquired by NZR it was classified separately and became the sole member of the [[NZR Oc class|OC class]].

'''SM40''' is a Polish code-name for a [[Hungary|Hungarian]] shunting and maneuvering purpose [[diesel electric locomotive]] after export from Hungary to Poland and in service at [[Polish State Railways|PKP]].

==History==
SM40 were imported for the first time from [[Hungary]] in 1959, after tests at the distance of 2,185 km with cargo load of 156 t.

The first name for this loco was Lwe58, and in 1960 it was changed to SM40 (according to RN-58/MK0001 regulations).

Items delivered from 1961 had a few modifications, and a different code-name [[SM41]].

'''SU42''' is a Polish [[diesel-electric locomotive]] used for light freight and passenger traffic purposes.

==History==
The SU42 is in fact the same locomotive as [[PKP class SM42|SM42]] and [[PKP class SP42|SP42]]. The original class SU42 were modifications of class SM42 done during the 1970s. This modification involved the installation of a 500 volt [[electric train supply]] for carriage heating, supplied directly by locomotive's generator. The class retained the original SM42 serial number, however most of those converted have now been converted back to SM42 or withdrawn as the carriages using 500 V supply have been withdrawn.

The second phase of modification was carried out between 1999 and 2000 from class SP42. The modification centered on the addition of 3 kV electric train supply. The modified locomotives were classified as class SU42-5xx. 40 of the class were eventually modified and they are based at various depots across the network. Unlike previous iteration, SU42-5xx has electric train heating powered by a separate Caterpillar diesel engine, thus not creating additional load on the locomotive's main engine while heating the train.

Built for shunting purposes, SM42, together with its version SU42, are widely used in passenger traffic on non-electrified lines.

==Later modifications==
In the 2000s, a number of companies started offering comprehensive rebuilds of the locomotive, involving the replacement of the [[Prime mover (locomotive)|prime mover]], [[Electric generator|generator]] and air compressors, upgraded driver's cab (that better isolates against the engine vibrations the original locomotive was famous for) and various changes to the body.<ref>{{cite journal |first=Zygmunt |last=Marciniak |date=April 2011 |title=Lokomotywy elektryczne i spalinowe zmodernizowane w Polsce w ostatnich latach |trans-title= Electric and diesel locomotives modernised in Poland |url=http://yadda.icm.edu.pl/baztech/element/bwmeta1.element.baztech-article-BPK3-0006-0019/c/Marciniak.pdf |journal=TTS Technika Transportu Szynowego |publisher=Instytut Naukowo-Wydawniczy "TTS" Sp. z o.o. |volume=18 |issue=4 2001 |pages=27–32, 34 |issn=1232-3829 |via=BazTech Polish Technical Periodicals Database |language=pl}}</ref> [[Newag]] offers modification to type 6Dl that is equipped with 3 kV electric train heating.<ref>{{cite web |title=6Dl |url=https://www.newag.pl/en/offer/6di/ |website=Newag SA }}</ref>

Other modifications do not offer the electric train heating, making the modified locomotive a member of the SM42 class. Some of the companies that offer these modifications are:

==Nicknames==
The described loco used to be called by the following names:
*'''Zebra''' or '''stonka''' (''[[Colorado potato beetle|Colorado beetle]]'') – from the original livery
*'''Wibrator''' (''[[Vibrator (mechanical)|Vibrator]]'') – from the vibrations the engine produced
*'''Eleska''' – from the factory designation: Ls800
*'''Fablok''' – from the producer
*'''Polsat''' – from the livery similar to one of Polish popular TV operators' colours

The '''SM15''' (factory designation '''12D''') is a Polish diesel [[shunter]] used by [[Polskie Koleje Państwowe|PKP]] and industry <ref>{{cite web| url=http://157.158.1.11/~uboottd/jareks/assort/VIII.htm| title=Chester Home Page| author=Jarek D. Stwarz| date=1997–2002| accessdate=2007-08-30}}</ref> — where it carried the designation '''Ls750H'''. It is based on the Soviet '''ТГМ3''' (TGM3) locomotive.

==History==
[[File:DieselLoco tgm3.jpg|thumb|left|[[Soviet Union|Soviet]] '''ТГМ3''' locomotive — the predecessor of the SM15 — at the [[Sankt Petersburg|St. Petersburg]] Railway Museum.]]

Between the years 1963–1966, a total of 56 locomotives had been produced — 27 of which were used by [[Polskie Koleje Państwowe|PKP]].<ref>{{cite web| url=http://koleje.webd.pl/forum/viewtopic.php?t=569&sid=3011dc1ca59539d7d71d680887e19428| title=Fora Kolejowe| date=2007-01-18| accessdate=2007-08-30}}</ref> Of the latter 27, the first two units (SM15-01 and SM15-02) were built at the '''Людиновский тепловозостроительный завод''' (en: [[Lyudinovo]] Diesel Locomotive Factory) and exported to Poland. Production then resumed at the [[Fablok]] factory in [[Chrzanów]] where the remaining 25 units, earmarked for PKP, were built.

The newly built SM15s were assigned to the depot in Kraków Płaszów, before being withdrawn from service in the late 1960s and early 1970s, when the [[SM42]] series replaced them. Despite their relatively short operational history, the [[railroad engineer|engineers]] who drove the locomotives remember them as being very powerful machines.

==Technical data==
The SM15 is equipped with a [[Soviet Union|Soviet]] 550 kW [[diesel engine]] (a number of SM15s had Polish V12CD9 engines installed, rather than the Soviet variant) with [[hydromechanics|hydromechanical]] [[transmission (mechanics)|transmission]]. Certain models destined for use in industry had [[hydraulics|hydraulic]] transmission, and these carried the designation '''Ls750Hu'''. The SM15 is a [[B′B′]] locomotive, which means that the unit runs on two [[bogie]]s, with all axles powered.

The main reason behind the SM15's short operational lifespan was the unreliability of its transmission and power units.

==Preserved Units==
Currently, there are three known examples of the SM15 in preservation:

*'''SM15-17''' is an exhibit at the [[Warsaw Railway Museum]]
*'''SM15-22''' has been kept back as a [[monument]] at the Technical Rail College in [[Tarnowskie Góry]]

'''Ok1''' is the Polish designation of a [[Prussia]]n [[steam locomotive]], the [[Prussian P 8]], used on [[Polskie Koleje Państwowe|Polish State Railways]]. Production of the P 8 lasted from 1908 until 1928 and this locomotive was used on practically all European railway lines.

After the end of [[World War I]], 192 Class P 8 engines were handed over as a reparation to Poland, including two machines for [[Free City of Danzig]], where they were re-designated as Class Ok1 locomotives (numbers: Ok1-1 to Ok1-190 and Ok1-1Dz and 2Dz for Danzig machines).<ref name=atlas>Terczyński, P. (2003), pp. 52, 56</ref> Since the class was considered successful, further 65 locomotives were built in Germany at Polish order in 1922-1923 (designated Ok1-201 to 265).<ref name=atlas/>

[[File:Ok 1-322 Wolsztyn 12.10.05.jpg|thumb|left|Ok1-359 in Wolsztyn]]
During [[World War II]] all the locomotives were captured by the Germans or Soviets and most were pressed into the German Railways. After the war, along with new war reparations, Poland received 429 locomotives P 8 (numbers Ok1-1 to 429), what made it by far the most numerous passenger locomotive in the country.<ref name=atlas/> They were used until the late 1970s - last locomotive was withdrawn from line service in 1981.<ref name=atlas/> A few engines were preserved, including Ok1-359 (see the photograph), which is stabled at the [[Wolsztyn museum]].

'''PKP class OKl27''' is a class of ordinary passenger ('''O''') [[tank locomotive|tank]] ('''K''') [[2-6-2]] ('''l''') [[steam locomotive]]s designed in 19'''27''' for [[Polskie Koleje Państwowe]] (Polish State Railways, PKP). It was the first completely [[Poland|Polish]] construction. The design was prepared by eng. Bryling.

==History==

===Production===
[[H. Cegielski - Poznań S.A.|Hipolit Cegielski Metal Works]] in [[Poznań]] produced 122 engines in the period of 1928–1933.{{sfn|Durrant|1972|pp=109–110}}

===Operation===
The OKl27 class serviced mainly local transport, especially suburban lines.

===Wartime===
After the German invasion of Poland in World War II, 107 of the 122 OKl27 locomotives were taken into the [[Deutsche Reichsbahn]] fleet as 75 1201 to 75 1307. The remaining 15 were taken into the stock of the Soviet Railways; all but two of which came into German hands and were renumbered 75 1308 to 75 1320.{{sfnb|Hütter|2021|p=194}}

After the war, most locomotives were restored to Poland and renumbered. While the post-war class remained the same, locomotives were renumbered at random, so a locomotive's pre- and post war identities are (usually) completely different.{{sfnb|Hütter|2021|pp=195–197}}

===Preservation===
Four engines have survived:
*OKl27-10 in [[Skierniewice]] (as an exhibit),
*OKl27-26 in [[Warsaw]] ''Railroad Museum'' (as an exhibit),
*OKl27-27 in [[Gdynia]] (as an exhibit), and
*OKl27-41 in [[Chabówka]].

The [[London and North Western Railway]] (LNWR) '''"Precursor Tank" Class''' was a type of [[4-4-2T|4-4-2 tank]] [[steam locomotive]].<ref name="Engineer-1910-09-23">{{cite magazine |author= |date=23 September 1910 |title=Passenger Tank Engines.

Chronologically, the class was constructed three distinct blocks, from May to September 1906 (works nos. 4560–4589), March to April 1907 (4590–4599), and March to April 1909 (4820–4829). The first 30 locomotives had {{convert|3|ft|9|in|m|3|abbr=on}} carrying wheels, but the size of these was reduced to {{convert|3|ft|3|in|m|3|abbr=on}} thereafter.<ref name="Baxter"/>

The LNWR reused numbers from withdrawn locomotives, so the numbering system was completely haphazard. The 3 ft 9 in engines were numbered by 528, 531, 784, 1295, 1305, 1981–1985, 97, 111, 181, 196, 562, 616, 803, 1356, 1508, 2210, 139, 653, 834, 874, 1506, 1572, 1589, 1671, 1714, and 2165. The 3 ft 3 in engines were numbered 44, 527, 612, 762, 827, 875, 1427, 1764, 2196, 2446, 920, 935, 1164, 1219, 1523, 1536, 1551, 2077, 2223 and 2228.

All fifty passed into LMS ownership in 1923. The LMS gave them the [[power classification]] 2P. The LMS also renumbered them into solid block of numbers: 6780–6809 for the 3 ft 9 in engines and 6810–6829 for the 3 ft 3 in engines, in the order given above.

Due to their weight, the Precursor Tanks were unable to operate on some branch lines, but had primarily been designed for use on heavy suburban trains.<ref>{{cite book |last=Montagu |first=George |date=1907 |title=Ten Years of Locomotive Progress |url=https://babel.hathitrust.org/cgi/pt?id=hvd.hb4dz5&view=1up&seq=175 |location=London |publisher=Alston Rivers Ltd. |page=137 |via=[[HathiTrust]]}}</ref><ref name="LN67">{{cite magazine |author= |date=10 December 1921 |title=The "Precursor Tank" Locomotives of the London and North-western Railway |url=https://babel.hathitrust.org/cgi/pt?id=uiug.30112088589822&view=1up&seq=569 |url-access=limited |magazine=The Locomotive News and Railway Notes |volume=10 |number=67 |pages=137–138 |via=HathiTrust}}</ref> Initially, they were put to work on local services between [[Sutton Coldfield]] and [[Birmingham]], and also between [[Watford]] and London {{rws|Euston}}.{{sfnp|LNWR|1908|p=32}} In 1921, they were reported as being employed on the latter to the near-total exclusion of other locomotive types, as well as on other routes.<ref name="LN67"/> 1572, which was possibly one of the earliest locomotives to have the initials "L&NWR" on its sides replaced by "LMS", was noted to be working on the [[Morecambe branch line|Morecambe branch]] in 1923.<ref>{{cite magazine |last=Stones |first=H.

The '''EU20''' is an [[electric locomotive]] type formerly operated by the [[Polish State Railways]] (PKP) in [[Poland]].

==History==
In production for a mere three years (1955–1958), the series was built at the ''[[LEW Hennigsdorf|Lokomotivbau Elektrotechnische Werke]]'' works — commonly shortened to ''LEW'' — in [[Hennigsdorf]], East Germany. During this time, 34 units were produced with the intention for use as a [[mixed-traffic locomotive|mixed-traffic]] locomotive – hence its [[Polish_locomotives_designation#Electric_and_diesel_locomotives|EU designation]] – though the reality is that the EU20 saw more use as a freight locomotive than a passenger one. EU20s were the first electric locomotives to be used on the route between [[Warsaw]] and [[Silesia]].

The class gained notoriety for its frequent breakdowns due to overheating of [[resistors]], and the lack of additional cooling facilities found in other locomotives.

==Technical data==
Mechanically, the EU20 was identical to the earlier EU04 (also built by LEW), sharing the same traction engines, [[rectifier]]s, and [[gas compressor]]s.

==Operational history==
During the series' 26-year service, most units were assigned to the [[Piotrków Trybunalski]] depot. EU20s were withdrawn over a 6-year period, beginning in 1976, with the last locomotive being withdrawn in 1981.

==Preservation==
'''EU20-24''' has been{{when|date=December 2014}} preserved as an exhibit at the [[Warsaw Railway Museum]], and is the only surviving example from the series.

'''ET41''' (manufacturer's designation: '''HCP 203E)''' is the name for a [[Poland|Polish]] [[electric locomotive]] used by the [[Poland|Polish]] railway operator (''[[Polskie Koleje Państwowe|PKP]]''). Three such locomotives were briefly rented to the [[Croatian Railways]] between 1995 and 1996 and were given the designation '''HŽ series 1081''' there.<ref>{{Cite web |url=http://www.railfaneurope.net/ric/1081.htm |title=1081 |access-date=21 November 2007 |archive-date=18 March 2012 |archive-url=https://web.archive.org/web/20120318232611/http://www.railfaneurope.net/ric/1081.htm |url-status=live }}</ref>

==History==
ET41 is a modification of the [[PKP class EU07|EU07]] locomotive, and was designed for the purpose of heavy cargo transport. It is made of two connected bodies of EU07, minus the cabs at the inner ends.

===Introduction===
The design for this machine was ready in 1976. Basically it consists of two EU07 locomotives but with two driver's cabs removed. Two locos are semi-permanently coupled in multiple operation. Because of this, the current collection must be done independently for each section.

===Production===
Production started in 1977 and continued until 1983. A total number of 200 double-locomotives were produced.

Half-locomotives 036B, 088A and 116A have been rebuilt as [[PKP class EU07|PKP EU07-537]], EU07-544 and PKP EU07-545 respectively. This has required cabs to be built at the back end.<ref>{{cite web|title=EU07 and EP07|url=http://www.locomotives.com.pl/Electric%20Locomotives/EU07.htm|access-date=30 July 2014|archive-date=8 August 2014|archive-url=https://web.archive.org/web/20140808051219/http://www.locomotives.com.pl/Electric%20Locomotives/EU07.htm|url-status=live}}</ref>

===Present day{{when|date=July 2014}}===
ET41 are mainly used for [[coal]] transport from [[Upper Silesia]] to the ports of [[Gdańsk]], [[Gdynia]] and [[Szczecin]]. Seldom are those locomotives used for hauling passenger trains.{{Cn|date=July 2023}} In 2016, [[PKP Cargo]] decided to send some ET41 locomotives for major repair and modernization to [[Ostrów Wielkopolski]]. The locomotives received overhauled electrical equipment, bogies, and traction motors, as well as revamped driver's cabs. The first locomotive to be modernized, ET41-006, was shown off on 14 October 2016.<ref>{{Cite web |date=2016-10-14 |title=PKP CARGO received the first modernized locomotive of ET41 series |url=https://www.pkpcargo.com/en/media-relations/press-releases/pkp-cargo-received-the-first-modernized-locomotive-of-et41-series/ |access-date=2023-07-31 |website=PKP Cargo |language=en |archive-date=2 August 2023 |archive-url=https://web.archive.org/web/20230802133749/https://www.pkpcargo.com/en/media-relations/press-releases/pkp-cargo-received-the-first-modernized-locomotive-of-et41-series/ |url-status=live }}</ref>

The [[Southern Railway (Great Britain)|Southern Railway]] '''E1/R''' was a class of [[0-6-2]]T tank [[steam locomotive]] designed for light passenger and freight duties. They were rebuilt from earlier [[London, Brighton and South Coast Railway|LB&SCR]] [[LB&SCR E1 class|E1 class]] [[0-6-0]]T locomotives originally built 1874–1883. The rebuilt locomotives were intended to be used in the West of England.

==Construction==
In 1927, there was a surplus of the Stroudley ‘E’ tanks in service on the Central Section of the Southern Railway, many of which were in good condition as they had been fitted with larger boilers by [[D. E. Marsh]] after 1911. At the same time there was a need for additional [[tank locomotive]]s in the Western Section for use in shunting, station piloting and particularly for services on the [[North Cornwall Railway|North Cornwall line]] to [[Padstow]].<ref>Bradley, (1972), 34, 37.</ref>

Ten locomotives had their frames extended, bunkers and water tanks enlarged at Brighton works over the next two years.<ref>{{Cite book |last=Garner |first=Rod |title=The Southern Way: Issue No. 1 |publisher=Noodle Books |year=2007 |isbn=9780955411038 |pages=22–33}}</ref> A [[Bissel truck|pony truck]] of the same design as a [[SECR N class|’N’ class]] locomotive was also added to create a [[radial axle|radial]] trailing axle, making them [[0-6-2]]T. The rebuilt locomotives were dispatched to the Western section during 1928 and 1929 and found to be successful. Some complaints from passengers about rough riding on the meandering North Cornwall line were addressed by having the locomotives on this line re-balanced during 1936 while other locomotives that weren't balanced were restricted to local and shunting and banking duties.<ref>Bradley, (1972), 45-6.</ref>

The new class performed well for nearly twenty years but withdrawal commenced in 1955 and they were finally all replaced by [[George Ivatt|Ivatt's]] [[LMS Ivatt Class 2 2-6-2T|prairie tanks]] by 1959.

The '''Caledonian Railway 300 Class''' were freight [[0-6-0]] [[Steam locomotive|tender engines]] introduced in 1918 and designed by [[William Pickersgill]]. Forty-three were built between 1918 and 1920. They were numbered 294–324, 280, 281, 670–679 by the [[Caledonian Railway]].

== Design ==
The locomotives were based on the [[Caledonian Railway 30 Class]], a superheated version of the [[Caledonian Railway 812 and 652 Classes|Caledonian Railway 652 Class]], both designed by [[John F. McIntosh|John F McIntosh]]. They were introduced between 1918 and 1920 at [[Glasgow Works|St. Rollox Works]], [[Glasgow]], being built in a series of 4 batches (St. Rollox Lot No. Y119-Y120, Y122-Y123). The cylinders were reduced in diameter by 1in from the 30 Class, though the wheelbase, wheel spacing and wheel diameter was the same.

The 300 Class would have several variations of the basic design during production. These would mainly involve [[Superheater|superheating]] and the inclusion of [[Piston valve (steam engine)|piston]] or [[slide valve]]s, with each combination of valves and boiler being constructed.

Visually, the locomotives looked similar to the 30 Class, with the main differences being the absence of the raised front running board in front of the [[smokebox]] and cylinders and the wing plates on the side of the smokebox.

The first 12 members of the class (300-311) were constructed with steel [[Firebox (steam engine)|fireboxes]]. Later locomotives would have copper fireboxes and the steel fireboxes on these members would be replace with copper ones by 1922.<ref>{{Cite web |title=CR/LMS Pickersgill "300" Class 0-6-0 - Summary |url=https://www.brdatabase.info/locoqry.php?action=class&type=S&id=406040 |access-date=2024-02-12 |website=www.brdatabase.info}}</ref>

In 1925, No. 305 and 317 (Now renumbered LMS 17661 and 17673 respectively) were fitted with [[vacuum ejector]]s.<ref>{{Cite web |title=CR/LMS Pickersgill "300" Class 0-6-0 - Modifications |url=https://www.brdatabase.info/locoqry.php?action=class&id=406040&type=S&page=mods |access-date=2024-02-12 |website=www.brdatabase.info}}</ref> This was so that they could use [[Vacuum brake|continuous vacuum brakes]] on compatible rolling stock, primarily passenger trains.

==Ownership changes==
{{Unsourced|section|date=January 2025}}
In 1923, they all passed to the [[London, Midland and Scottish Railway]], and were classified [[Power classification|3F]], and renumbered 17650–17692, along with gaining additional lamp irons. On nationalisation in 1948, the twenty-nine survivors passed into [[British Railways]] stock, and were renumbered by adding 40000 to their LMS numbers.

;Note 1
Not all the BR numbers were actually applied because some engines had been withdrawn before 1948. They were withdrawn between 1934 and 1963, and all were scrapped.

== Withdrawal ==
The first withdrawal of the class was LMS 17657 (CR 302) in Nov 1934 after a service life of 16 years, 9 months.<ref>{{Cite web |title=Caledonian Railway No. 301 locomotive data |url=https://www.brdatabase.info/locoqry.php?action=locodata&id=406040002&type=S&loco=301 |access-date=2024-02-12 |website=www.brdatabase.info}}</ref> 14 class members would be withdrawn between 1934 and 1939 before withdrawals were paused due to the [[World War II|Second World War]]. LMS 17687 (CR 674) and 17662 (CR 306) were withdrawn in March and July 1939 respectively but was reinstated by the LMS in 1940 before being withdrawn again after the war.<ref>{{Cite web |title=Caledonian Railway No. 306 locomotive data |url=https://www.brdatabase.info/locoqry.php?action=locodata&id=406040007&type=S&loco=306 |access-date=2024-02-12 |website=www.brdatabase.info}}</ref><ref>{{Cite web |title=Caledonian Railway No. 674 locomotive data |url=https://www.brdatabase.info/locoqry.php?action=locodata&id=406040038&type=S&loco=674 |access-date=2024-02-12 |website=www.brdatabase.info}}</ref>

The remaining 29 made it into BR ownership from 1st Jan 1948. Withdrawals restarted in 1961 and all would be withdrawn over the next two years, with the final two 300 Class locomotives, BR 57679 (LMS 17679, CR 323) and BR 57688 (LMS 17688, CR 675) both being withdrawn on the 29th of Nov 1963.<ref>{{Cite web |title=Caledonian Railway No. 323 locomotive data |url=https://www.brdatabase.info/locoqry.php?action=locodata&id=406040030&type=S&loco=323 |access-date=2024-02-12 |website=www.brdatabase.info}}</ref><ref>{{Cite web |title=Caledonian Railway No. 675 locomotive data |url=https://www.brdatabase.info/locoqry.php?action=locodata&id=406040039&type=S&loco=675 |access-date=2024-02-12 |website=www.brdatabase.info}}</ref>

The '''Caledonian Railway 812 and 652 Classes''' were 0-6-0 steam [[tender locomotive]]s designed by [[John F. McIntosh]] for the [[Caledonian Railway]] and introduced in 1899. They had the same boiler type as the [[Caledonian Railway 721 Class|721 “Dunalastair” Class]] [[4-4-0]]s. They could reach speeds of up to {{cvt|55|mph|km/h}}.<ref>{{cite book |title=Train: The Definitive Visual History |publisher=DK Press |page=98}}</ref>

Only three, 17567, 17598 and 17610 (all 812s), had been withdrawn by the time of nationalisation in 1948. The last locomotive in service was not withdrawn until 1963.

Locomotive 828 (LMS 17566, BR 57566) is the sole survivor of the class and is an important example of Scottish industrial heritage. It is based at the [[Strathspey Railway (preserved)|Strathspey Railway]]. It was returned to regular service in 2010 and then again in March 2017 following heavy repairs. 828 is the final member of the first batch of engines built in 1899. Since 2022 it has been on long term hire to the [[Spa Valley Railway]] in Kent.<ref>{{Cite web |date=2021-11-12 |title=Spa Valley Railway to welcome Caledonian Railway steam locomotive No. 828 |url=https://www.railadvent.co.uk/2021/11/spa-valley-railway-to-welcome-caledonian-railway-steam-locomotive-no-828.html |access-date=2024-05-18 |website=RailAdvent |language=en-GB}}</ref> where it joined fellow Caledonian survivor [[Caledonian Railway 439 Class|419]] during the Scottish Steam Up over Easter 2022.<ref>{{Cite web |title=Scottish Steam Up! « Spa Valley Railway |url=https://www.spavalleyrailway.co.uk/product.php/297/scottish-steam-up#:~:text=The%20Scottish%20Steam%20Up%20took,event%20in%20our%20railways%20history. |access-date=2024-05-18 |website=www.spavalleyrailway.co.uk}}</ref>

[[Belgian State Railways]] (SNCB-NMBS) derived three series of steam locomotives (891 units) from the class 812 between 1899 and 1914. They had a shallower [[Firebox (steam engine)|firebox]], able to burn semi-bituminous coal and [[briquette]]s, allowing a shorter wheelbase due to its positioning above the rear axle. There were three classes:
*[[Belgian State Railways Type 30|Type 30]] – first variant with several details in common with the Caledonian engines (cab windows, gauges, and tender coupling). 82 built between 1899 and 1901.
*[[Belgian State Railways Type 32|Type 32]] (later renamed Type 44) – more powerful and fitted with a Belgian cab, higher steam pressure, new gauges and tender coupling. 502 built between 1901 and 1910.
*{{Interlanguage link|Belgian State Railways Type 32S|lt=Type 32S|fr|Type 41 (SNCB)|WD=}} (later renamed Type 41) – same features but improved with a Schmidt [[superheater]]. 307 built between 1905 and 1914.
Until 1909, they were the only new engines used with freight trains. They were also used on suburban and local passenger trains and some expresses on hilly sections. Most of them were retired between 1947 and 1959. Some of them were then used as stationary boilers and two of them (44.225 and 41.195) survive in museums. A third one (44.021) was kept as a parts donor and scrapped in 2002.<ref>{{Cite web |url=https://www.internationalsteam.co.uk/tales/belgiumtales01.htm |title=Former Belgian Steam Heating Locomotives |access-date=25 May 2018 |archive-date=25 May 2018 |archive-url=https://web.archive.org/web/20180525133700/http://www.internationalsteam.co.uk/tales/belgiumtales01.htm |url-status=live }}</ref>

The [[North Eastern Railway (UK)|North Eastern Railway]] '''Class T3''', classified as '''Class Q7''' by the [[London and North Eastern Railway|LNER]], is a class of {{whyte|0-8-0}} [[steam locomotive]] designed for heavy freight. Five were built by the NER in 1919 and a further 10 by the [[London and North Eastern Railway]] (LNER) in 1924.<ref>{{Cite book |last=Wragg |first=David |url=https://books.google.com/books?id=A0YwDwAAQBAJ |title=The LNER Handbook: The London and North Eastern Railway 1923-47 |date=2017-07-03 |publisher=The History Press |isbn=978-0-7509-8482-9 |language=en}}</ref>

==Performance==
The first of the T3s, No.901 was outshopped from [[Darlington Works]] in November 1919. A month later the NER organised a test train, over the [[Newcastle upon Tyne|Newcastle]] to [[Carlisle railway station|Carlisle]] line, including a [[brake van]] and the company's [[dynamometer car]] to record the locomotive's performance. No.901 had {{convert|1,402|LT|t ST}} in tow but handled the load with ease, registering both high power and steady acceleration. There were no problems starting on a 1 in 298 (0.335 [[Percent sign|%]]) grade and on the return, with a reduced load of {{convert|787|LT|t ST}}, the engine was untroubled by gradients as severe as 1 in 107 (0.93%).

==LNER==
Despite their prowess, the original quintet of T3s was not augmented by the North Eastern Railway, a move that would have pleased footplate crews who disliked having to [[Lubrication|lubricate]] and maintain the centre cylinder and valve gear. Instead the enlargement of the class came under LNER. it authorised the construction of ten additional T3s and these emerged from Darlington Works during 1924.

Of the new engines two were allocated to [[York]] and a further four went to [[Kingston upon Hull|Hull]]. The remaining four gravitated to their natural habitat, [[Tyne Dock]] depot near [[South Shields]]. It was there eventually that all 15 T3s/Q7s congregated. Here they performed the role they were designed for. This was to haul {{convert|700|LT|t ST|adj=on}} rakes of [[iron ore]] [[Hopper car|hoppers]] to the [[steelworks]] at [[Consett]] {{convert|1000|ft|m|0|abbr=on}} above [[sea level]]. On the steepest section, as severe as 1 in 35 (2.86%) in places, one 0-8-0 pulled while another [[Bank engine|pushed]].

==British Railways==
All 15 passed into [[British Railways]] ownership in 1948 and they were numbered '''63460-63474'''. They remained master of their task till the arrival of [[BR Standard Class 9F]] {{whyte|2-10-0}}s in the 1950s. With the loss of their bread and butter work British Railways retired all 15 of the Q7s in November and December 1962.

==Preservation==
One, NER 901 (BR 63460) has survived and is currently on display at [[Darlington Railway Centre and Museum]]. It is the newest exhibit at the museum.

==Models==
DJH Models has made a kit for 1:76 ([[OO gauge]]) of the class<ref>{{Cite web|url=https://www.djhmodelloco.co.uk/product/k17-kit-ner-t3-lner-br-q7-0-8-0/|title=K17 Kit - NER T3 (Later LNER/BR Q7) 0-8-0}}</ref>
