The steam locomotive series SB M was a narrow gauge - tank locomotive of the Southern Railway Company (SB), a private railway company of Austria-Hungary .
The Mödling – Hinterbrühl local railway was the first electric railway in Europe that was suitable for continuous operation. Nevertheless, given the state of the art at the time, it was considered necessary to purchase a steam locomotive as a reserve, which should be used for repairs in the event of a power failure. The SB, which ran operations on the local railway, therefore ordered a small, double-coupled tank locomotive with a gauge of 1,000 mm from the Floridsdorf locomotive factory . The locomotive was delivered in 1884 and was initially designated as series A, but soon as series M and was given the operating number 1. The designation as series M was probably based on the series scheme of the kkStB , which in the case of narrow-gauge locomotives was named according to the first place of use ( Mödling ) provided.
The machine had capacitors on both sides next to the boiler . The water supplies were housed in the frame under the boiler and above the axles. It was fired with coke to keep smoke levels down in the urban area.
The locomotive lived up to expectations, but was only used sporadically that it was rented to the Korenicani forest railway in Slavonia in 1887 and sold to them in 1897.
