Prussian T 37
The T 37 series vehicles were locomotives of the Prussian State Railways . They were used on the Upper Silesian narrow-gauge railways . A total of 20 machines were delivered, eight of which with the numbers 99 401 to 99 408 were taken over by the Reichsbahn . The machines were all taken out of service and scrapped by 1939.
The locomotives differed according to their manufacturers.
What they had in common was that they were equipped with Klien-Lindner type end axles . The locomotives had an outer frame, and they also had double buffers, as is common on standard-gauge railways, later connected with a wide beam so that cars with central buffers could also be moved. They had no continuous brakes, and because they were needed for freight transport, no steam heating either. They had an external Heusinger control. The coal container was located behind the driver's cab.

The first two locomotives were built by the Sächsische Maschinenfabrik in 1902 . They had similarities with the Saxon VK , which was built by the same manufacturer , but unlike the one they had no connection. The drive took place on the second axis. The first and fourth axles were each designed as a Klien-Lindner hollow axle , so that the locomotive could also travel through bends with a 35 m radius.

1904–1906 Orenstein & Koppel delivered ten locomotives, with the numbers 11–20, (from 1910 Kattowitz 113–122), in 1910 another two locomotives (23 and 24, Kattowitz 125–126) and in 1912 another four (Kattowitz 127–130 ). Seven locomotives were still taken over by the Deutsche Reichsbahn and designated as 99 401-408 (without 406). In these locomotives the third axle was driven. The middle axes had a side play of 20 mm. The vehicles could hold 1.3 tons of coal and 2.5 m² of water.
Hagans type
In 1909, the Christian Hagans machine factory delivered two locomotives, numbers 21 and 22 (Kattowitz 123–124), the 124 came to the Deutsche Reichsbahn as 99 406.
