The [[steam locomotives]] of '''DB Class 10''' were [[express train|express]] locomotives with the [[Deutsche Bundesbahn]] in [[West Germany|Germany]] after the [[Second World War]]. They were nicknamed 'Black Swans' ('schwarze Schwäne') as a result of their elegant shape.
== History ==
These newly designed locomotives were built by the firm of [[Krupp]] and delivered to the DB in 1957. The two examples of this class were given operating numbers 10 001 and 10 002. They had originally been seen as a replacement for the [[DRG Class 01]] and [[DRG Class 01.10|Class 01.10]]. However, as a result of their late delivery, high axle load of over 22 tonnes (which restricted its use to only a few routes) and structural changes to rail operations, this plan did not come to fruition. Both engines were designed to greatly reduce maintenance and repair costs.<ref>Ransome-Wallis (1959), p. 348, column 1.</ref> They had a conical [[smokebox]] door and partial streamlining which protected the cylinders from dirt and from cooling too rapidly and, at the same time, was supposed to reduce wind resistance. The fully welded boiler was the same as the newly designed one used to re-equip the [[DRG Class 01.10]] from 1953. 

The two engines differed initially in their firing. Number 10 001 only had supplementary oil-firing to start with, thus relieving the stoker of up to 30% of his work,<ref>Ransome-Wallis (1959), p. 348, column 2.</ref> but was later converted so that it was fully oil-fired, as 10 002 had been from the outset. 

Both vehicles were equipped with a newly designed [[tender (rail)|tender]] of Class 2′2′&nbsp;T&nbsp;40.

Locomotives 10 001 and 10 002 were only permitted to work on certain main lines as heavy express steam locomotives due to their [[axle load]] of 22 tonnes. Up to 1962 they were allocated to [[Bebra]] [[locomotive depot]] (''[[Bahnbetriebswerk (steam locomotive)|Bahnbetriebswerk]]'' or ''Bw''), before being transferred to ''Bw'' [[Kassel]] where they worked alongside the [[DRG Class 01.10]]s until 20 March 1967 heading fast-stopping and express trains to and from [[Gießen]]. Number 10 001 hauled the E 387/388 (E 687/688) fast-stopping services to and from [[Münster (Westfalen)|Münster]] almost without a break from 21 March 1967 to the beginning of January 1968, and for one month even had special permission to continue as far as [[Rheine]] (which part of the route was only cleared for 20 tonne axle loads). 

Locomotive 10 002 was retired after a side rod broke in January 1967 and number 10 001 was retired on 27 June 1968.

No. 10 001 may be viewed at the [[German Steam Locomotive Museum]] (''Deutsche Dampflokomotiv-Museum'') in [[Neuenmarkt]]-Wirsberg. No. 10 002 was scrapped in 1972 at the [[Offenburg]] repair shop (''Ausbesserungswerk'' or ''Aw'').

The Class 10 was generally well-liked, especially by the staff at Kassel depot. Contrary to the claim commonly made in the literature that she was prone to damage, its long periods out of service were because spare parts were never available locally, unlike those of the Class 01.<ref>[[:de:DB Baureihe 10|German Wikipedia, DB Baureihe 10 article]]</ref>

==In fiction==
In the 2016 ''[[Thomas & Friends]]'' film ''[[Thomas & Friends: The Great Race|The Great Race]]'', a character named [[Thomas the Tank Engine film characters#Frieda|Frieda]] is based on the DB Class 10.<ref>[http://metro.co.uk/2016/04/06/thomas-friends-the-great-race-unveils-diverse-train-line-up-5798197/ ''Thomas & Friends The Great Race unveils diverse train line-up''], retrieved 6 Sep 2016.</ref>
