 and were to replace the T 5.1s on the Berlin Stadtbahn.

A 4-4-0T wheel arrangement promised to result in better riding qualities than those of the T 5.1. However the T 5.2s were less suited to running cab first due to the lack of a trailing axle and the large driving wheels, and so their employment was restricted to the Berlin ring.

In 1923 the Reichsbahn had still intended to include 20 locomotives as numbers 71 019, 020, 029 - 031 and 72 001–015 in their renumbering plan

, but only took over two of them into their final numbering scheme in 1925, with numbers 72 001 and 72 002. They were retired by 1926.

In 1941 two more engines from the Eutin-Lübeck Railway Company, built by Henschel in 1911, came into the Reichsbahn fleet. They were given numbers 72 001 and 002. One of the two engines, which had both been converted to superheated working, remained in the ownership of the Deutsche Reichsbahn in East Germany until 1955.

No examples of the Prussian Class T 5.2 locomotive have survived.

Prussian T 5.2 (Superheated)

The superheated variant of the Prussian T 5.was the first superheated tank locomotive in the Prussian state railways. They were built to a Schmidt design and had better performance than the saturated steam variant of the T 5.2. Externally they differed from the wet steam T 5.2 locomotive in that they had a higher smokebox
Smokebox

The smoke then enters the smokebox, and is exhausted to the atmosphere through the chimney .To assist...
