Wurttembergische 2-6-2 Locomotives in Germany


Class Details by Steve Llanso of Sweat House Media

Class T5-1910 / BR 75.001 (Locobase 5831)

Data from "Baureihe 75.0" on Alfred Gieseler's Dampmaschinen und Lokomotiven website at [link], last accessed 21 April 2019.

These commuter locomotives proved stable and fast enough to pull mainline express between Stuttgart and Immendingen. Built in 12 batches from 1910 to 1920, the class consisted of three slightly different specifications.These first sixteen had the fewest tubes and smallest tanks and bunkers of the three variants. The next batch is shown in Locobase 20547, the final and largest complement appear in Locobase 20548.


Class T5-1912 / BR 75.017 (Locobase 20547)

Data from "Baureihe 75.0" on Alfred Gieseler's Dampmaschinen und Lokomotiven website at[link], last accessed 21 April 2019.

These commuter locomotives proved stable and fast enough to pull mainline express between Stuttgart and Immendingen. Production began with the sixteen delivered in 1910 and shown in Locobase 5831.

Apparently, the Wurttemberg decided they needed more heating surface area and more fuel and water capacity. These thirteen locomotives had the most heating surface area of the three variants. The final and most numerous group appears in Locobase 20548.


Class T5-1914 / BR 75.038 (Locobase 20548)

Christian Lindecke [link] (visited 28 November 2003) for data, supplemented by [link], last accessed 12 May 2011.

These commuter locomotives proved stable and fast enough to pull mainline express between Stuttgart and Immendingen. Locobase 5831 describes the first sixteen locomotives delivered in 1910. Locobase 20547 covers the next thirteen engines, which had the most heating surface area of the three variants.

1914 saw the introduction of the definitive design, which had the greater capacity of the 1912 batch. The biggest change was the three-tube increase in superheater flues.

93 of the 96 were absorbed by the DRG and 89 of these survived World War II. Retirements began only in 1959 and ended on 20 June 1963, 75 042 made the last run of the class.
