Alsace-Lorraine T 17
originally D33 and French State Railway 1-232 TB 301 to 366
Germany 1905 66 produced
In order to be able to haul heavy passenger trains with a maximum axle load of 14 tonnes on branch lines, a tank locomotive with seven axles was required. Thus, the Reichseisenbahnen ordered a total of 66 locomotives from Grafenstaden in several batches with the 4-6-4T wheel arrangement and de Glehn four-cylinder compound engine. Although the locomotives briefly delivered almost 1,000 hp, they quickly reached their limits due to the low adhesive weight. After the Second World War, most of these locomotives were in Germany. Most of these came back to the SNCF and were retired by 1954. The Luxembourg CFL had also received some in the meantime.
