The steam locomotives of the class G 7 1 of the Prussian State Railways were four-way coupled freight locomotives. They were built from 1893 first by the company Stettiner Maschinenbau AG Vulcan , but later also by the other larger Prussian locomotive manufacturers. The boiler was taken over by the G 5 1 .
history
The locomotives were intended for heavy goods traffic, especially on steep inclines. Therefore, most of the locomotives went to the West German and Silesian directorates. Up to 1909 1,002 copies had been delivered to the Prussian State Railways. 1916/1917 a further 200 G 7 were one built since the First World War simple and robust locomotives were needed for military use. The imperial army railway in Austria had since 1916 as a series 274 35 pieces G 7.1 that were intended for use on the vice sprint Russian lines. The Lübeck-Büchener Eisenbahn procured three G 7 1s , which were built by Schwartzkopff in 1898 . Another seven locomotives went to the Gutehoffnungshütte . The Pfalzbahn set with its G 4 I 27 locomotives, which were designed after the model of 7.1 G, in their service.
After the First World War 142 locomotives were given to the PKP as reparations and classified as Tp1 . During Poland's wars with its eastern neighbors, some machines were used in armored trains.
As a result of the 1918 armistice, France also received numerous G7.1 locomotives, which were distributed among three railway companies :
- 7 machines (as G7.1 4301-4307) went to the administration of the chemins de fer d'Alsace et de Lorraine (AL); another 13 locomotives (G7.1 4308–4320) came to the AL as spoils of war
- the Compagnie des Chemins de fer de l'Est (EST) received 40 G7.1 (company numbers 4706-4745)
- the Compagnie du chemin de fer de Paris à Orléans (PO) received 43 G7.1 (1261–1303)
After the three networks in the state railway SNCF in 1938, the locomotives were combined in the 040 B series. Of the G7.1s taken over by the PO , 29 were still in service at the beginning of the Second World War ; apart from six, they were brought back to Germany by the German occupiers . The last G7.1 of the SNCF was retired in 1950.
In 1923 the Deutsche Reichsbahn took over 680 from the Prussian State Railways in their redesignation plan , in 1925 the locomotives 55 001–660 were redrawn. In 1935, 13 from the railways of the Saar region and one from France as 55 661-673 and 55 674 were added to the Reichsbahn's inventory. The three G 7 1s of the Lübeck-Büchener Railway were given the numbers 55 681–683 in 1938.
During the Second World War, 105 of the machines sold to Poland after the First World War were taken over into the inventory of the Reichsbahn. They received the numbers of machines that had already been retired. In addition, G 7 1 from Lithuania were classified as 55 274 and 55 691-694.
After the Second World War, the locomotives were mainly used in shunting services by the Deutsche Bundesbahn and were taken out of service by 1957. In the Deutsche Reichsbahn the last G-7 was one retired in 1966, including 55 642nd
55 669 was retired in 1964 and has been in the Transport Museum in Dresden ever since .
Remaining abroad
The 55 196, 393, 400, 493 and 553 remained on Austrian territory after the Second World War. In addition to 55 553, which was taken over in 1950, the ÖBB included them in their vehicle inventory as ÖBB series 655 , keeping the serial number . The last one to retire was the 655,393 in 1957. It was used for shunting in Stadlau station .
After the war, the PKP still had 99 Tp1 machines in service, which were retired by 1966, and ten machines in Hungary with the MÁV as 431.001-010.
The vehicles were equipped with type pr 3 T 12 and pr 3 T 16.5 tenders (built in 1916/17).
