Prussian T 3 - DRG Numbering

DRG Numbering

In 1925 the Deutsche Reichsbahn (DRG) took over 511 Prussian T 3s as their Class 89.70–75. The 473 locomotives of the older version were given numbers 89 7001–7456, 7473–7476 and 7499–7511. The 38 locomotives of the stronger design were given numbers 89 7457–7472 and 89 7477–7498.

In incorporating locomotives later on from private railways that they had taken over, the DRG were not very logical. As a result, Class 89.75 ended up with a mixture of various locomotives types, in some cases with numbers that followed directly on from one another.

• The locomotives whose numbers immediately followed the Prussian T3s, those with numbers 89 7512–7521, were not T 3s, but an industrial locomotive (Class Pudel which translates as "poodle") built by Jung for the former Bremen Harbour Railway that had been taken over by the DRG in 1930. These engines had a 15 t coupled axle load and were significantly heavier than the T 3. They had a Walschaerts valve gear and a small coal tank behind the cab.
• The T 3s of the BLE, taken over in 1938 by the DRG, were given numbers 89 7531–7540. Locomotive 89 7535 was transferred that same year to the Gardelegen-Neuhaldensleben-Weferlingen railway.
• Locomotive 89 7541, which also came from the BLE, only resembled the T 3 in terms of its frame and running gear. The dimensions of cylinders, grate and heating areas were different.
• The three T 3s from the KOE, which was taken ove rby the DRG in 1941, were given numbers 89 7556, 89 7557 and 89 7559. No. 89 7558 was no T 3, but a somewhat more powerful class, the Bismarck class industrial locomotive built by Henschel.
• The T 3 from the ZFE, taken over in 1943, was retired at the same time. The locomotives with numbers 89 7560–89 7564 were from a different class, that had a 12 t coupled axle load, but were no more powerful than the T 3.
