Pfalzbahn 0-6-2 Locomotives in Germany


Class Details by Steve Llanso of Sweat House Media

Class T 4 1 (1908) / BR 98.681 (Locobase 5810)

Data from Christian Lindecke's website [] (visited 2 Jan 2004) (translated by Google) and the US Military Railway Service Equipment Data Book for German Locomotives supplied by Allen Stanley from his extensive Rail Data Exchange in March 2004.

A decade after it had bought 7 local-traffic tanks, the Pfalzbahn returned to Krauss for 8 more. These had the same boiler, firebox, and cylinders, but operated at a higher boiler pressure and put more weight on the drivers.

When the DRG began numbering in 1923, this sub-class was numbered 98 681-688. At least three of this octet survived World War II, two (682 & 686) serving the Passau installation of the German BundesWehr until 1950 and 681 serving the airbase at Ludwigshafen until 1954.


Class T 4 1 / BR 98.6 (Locobase 5809)

Data from Christian Lindecke's website [] (visited 2 Jan 2004) (translated by Google).

As the neighbor of the K.Bay.Sts.B, the Pfalzbahn has similar requirements for a local-traffic tank engine. So Krauss delivered this septet. The heavier and more powerful repeat order is shown in Locobase 5810.

When the DRG began numbering in 1923, this sub-class was numbered 98 651-657. Retirements came in 1940.
