Bavarian G 4/5 N

German Reichsbahn class 564 and Polish State Railways Tr102

Germany 1905 7 produced
Die Lokomotive, January 1906

The G 4/5 N was a small class of Consolidations derived from the E I. Although it also used experiences from the two Vauclain E I built by Baldwin, it was a two-cylinder simple. It had a high pitched boiler with a firebox that stood on top of the frames. Krauss delivered seven in 1904 and 1905 which were among the first Bavarian locomotives to be designated in the new scheme. The later superheated four-cylinder compound G 4/5 H was not a direct successor. After World War I, four G 4/5 N remained in Germany and became Reichsbahn 56 401 to 56 404. Two others came to the PKP and became Tr102. The Reichsbahn withdrew their locomotives in 1927 and in Poland, they were gone before 1936.
