Prussian G 4.1

The Prussian genus G 4 consisted of six-coupled freight locomotives with a boiler pressure of 12 bar, which had the Prussian state railways in 1905 classified in the genus G 4. Among them were 16 locomotives of the Directorate Mainz, derived from the Hessian Ludwig Railway. These locomotives were delivered 1872-1896 and did not correspond to the Prussian standard design.

The later G 4.1 was a development of the G 3 Due to the increased boiler pressure was achieved a significant performance improvement. There were delivered 1884-1901 about 165 G 4.1, plus numerous alterations of locomotives came with originally 10 bar boiler pressure. There were not referred to all relevant locomotives as G 4.

After the end of World War II came from the cease-fire levies G per two piece 4 (as 272003-004 ) and G 4.1 ( 272001-002 ) to the Italian State Railways (FS ).

The German Reichsbahn saw in 1923 in its preliminary reclassification plan still 92 locomotives for renumbering in 53 before 7601-7692. 1925 but only 17 locomotives were provided with the numbers 53 7601-7617 for renumbering. The decommissioning took place until 1930.

The Lübeck- Büchener Railroad had two in 1892 and in 1893 built locomotives of this type, but this filed as G 3, and numbered them from before 1923.
