The '''Prussian Class G 7.1''' engines of the [[Prussian state railways]] were German {{whyte|0-8-0}} steam locomotives design for hauling goods trains.

==History==
They were first built in 1893 by the firm of [[Stettiner Maschinenbau AG Vulcan]], but later by the other larger Prussian locomotive manufacturers as well. The [[boiler]] was the same as that of the [[Prussian G 5.1|G 5.1]].

The locomotives were intended for heavy goods duties especially on hilly routes. As a result, most of the engines went to the western German and Silesian [[Eisenbahndirektion|railway divisions]]. By 1909, 1,002 examples had been delivered to the [[Prussian state railways]]. During the [[First World War]] simple and robust locomotives were required for military use. As a result, in 1916/1917 a further 200 G&nbsp;7.1s were built. From 1916, the ''k.u.k. Heeresbahn'' in [[Austrian Empire|Austria]] had 35 units of the Class G 7.1 which it named the '''Class 274'''. They were intended for use on the [[Russian gauge|broad gauge]] [[Russian Railways]]. The  [[Lübeck-Büchen Railway]] also bought three G 7.1s, which had been manufactured in 1898 by ''[[Berliner Maschinenbau|Schwartzkopff]]''. Another seven engines went to the ''[[Gutehoffnungshütte]]''. Even the [[Palatinate Railway]] placed 27 of its [[Palatine G 4.I|G 4']] in service; the design of these was based on the Prussian G 7.1.

In 1923 the [[Deutsche Reichsbahn]] took over no less than 680 from the Prussian state railways into its [[DRG renumbering plan for steam locomotives|renumbering plan]]; in 1925 they listed locomotive numbers '''55 001–660'''. In 1935, 14 more came from the [[Saar (League of Nations)|Saar]] railways Reichsbahn fleet as 55&nbsp;661 to 55&nbsp;674;{{sfnb|Weisbrod|1991|p=29}} this included one locomotive that the Saar Railways had acquired from Alsace-Lorraine for border services.{{sfnb|Hütter|2015|p=93}} The three G 7.1s with the Lübeck-Büchen Railway were given numbers 55 681–683 in 1938.{{sfnb|Weisbrod|1991|p=65}}

In the [[Second World War]] 105 G 7.1s were taken over from [[Poland]] into the Reichsbahn's inventory. They were given the numbers of engines already retired. In addition, G 7.1 engines from [[Lithuania]] were added as numbers 55 274 and 55 691-694.

After the Second World War, the locomotives that ended up in the [[Deutsche Bundesbahn]] were mainly used in [[shunting (rail)|shunting]] duties and were retired by 1957. In the [[Deutsche Reichsbahn (GDR)|Deutsche Reichsbahn in East Germany]] the last G 7.1 was not retired until 1966, including number 55 642.

==Preserved locomotives==

Locomotive 55 669 was retired in 1964 and has been displayed since in the [[Dresden Transport Museum]] in [[Dresden]]. [http://www.dampflokfoto.de/Lokp55-1.htm Photograph of the 55 669]

Locomotives 55&nbsp;196, 393, 400, 493 and 553 were left in Austrian territory after the Second World War. Apart from 55&nbsp;553, which had been taken over by 1950, the [[Austrian Federal Railway|ÖBB]] incorporated them into their '''ÖBB&nbsp;Class&nbsp;655''', retaining their serial numbers. The last one, 655.393, was withdrawn in 1957. Its task had been shunting at Stadlau station.

The vehicles were equipped with [[tender (rail)|tenders]] of classes pr 3 T 12 and pr 3 T 16.5 (built 1916/17).
