Alsace-Lorraine G 11, originally C 33 and G 8
French State Railway 1-151 TB 201 to 213
For heavy coal and ore traffic in Lorraine and Luxembourg, the Imperial Railways skipped eight-coupled locomotives and introduced the first German 2-10-0 in 1905. The wheel flanges of the second and third driving axles were weakened, while the fifth had a 15 mm play to both sides. In general these were De Glehn compounds, but in this case the high pressure cylinders were on the inside and the low pressure cylinders on the outside. On a 1.26 percent incline, they could either haul 356 tonnes at 40 km/h or 605 tonnes at 20 km/h.
At the time of their introduction, they were designated C 33. When the Prussian system was introduced only one year later, they became the G 8. With the next change in 1912, they now became the G 11. At this time, they had already been replaced by the two-cylinder simple and superheated G 10 in service with the heaviest trains. Starting in 1928, 13 were rebuilt into the 2-10-2T tank locomotives of the type T 19 which were simpled, but not superheated. While the last rebuilt locomotives where used until 1951, the unrebuilt ones had been retired by 1935.
