Prussian S 1
The class S 1 of the Prussian State Railways were express locomotives with the wheel arrangement 1B. There were three types of it. The oldest were the so-called burnouts from the Cologne-Mindener Eisenbahn-Gesellschaft , 30 of which were built between 1871 and 1874. Three of these locomotives were given the designation S 1 Hannover 34–36 in 1906. The other two types are described here.

The first series of the S 1 was the first compound machine for express train traffic in 1884 , which was manufactured for the Prussian State Railways . The cylinders that drove the second coupling axis were arranged between the guide axis and the first coupling axis. Because of this arrangement, the machines ran very smoothly. In most other German 1'B locomotives (e.g. the Saxon III ), however, the cylinders were located in front of the wheelset. A total of 14 locomotives of this type were built by Hanomag and Henschel between 1884 and 1887 .
The advantage of the composite construction was the fuel saving. These vehicles used around 15% less than comparable twin locomotives. However, the compound machines initially had design-related difficulties in approaching them, so that this was probably one of the reasons why the compound S 1 was not built. From this type of S 1 the P 3.2 was later developed , which had many similarities in construction.
The locomotives were all used in the Hanover Directorate. When they later became too weak for express train traffic, they were also used in passenger traffic. Most of the locomotives were decommissioned by 1914, and a few remained in stock until 1922.
The vehicles were traveling with a Tender equipped to type 3 T 12th

A total of 261 copies of the normal design of the S 1 were built between 1885 and 1898. They were also included in the Prussian standards . This type of locomotive was developed from the P 2 and P 3.1 passenger locomotives and was intended for express train traffic on long, straight routes such as Berlin – Stendal – Lehrte. In contrast to the other type of the S 1, the front barrel axis was again arranged behind the cylinder and the composite design was dispensed with. On the Berlin-Hamburg railway , they pulled passenger trains weighing 171 tons at a speed of 80 km / h. With the appearance of more powerful locomotives, they were pushed into passenger train service. The Essen directorate therefore classified its three locomotives as P 3 .
According to a preliminary re-drawing plan, four more with the numbers 12 7001–7004 were to be taken over from the Deutsche Reichsbahn ; this did not happen, however, since they were retired by 1925. Most of the locomotives had already been retired towards the end of the First World War .
The Polish state railways Polskie Koleje Państwowe (PKP) took over fourteen locomotives from the years 1890 to 1895 after the First World War. The comparatively light and weak machines were used for a short time in low passenger train service. In the designation scheme introduced in 1922, the Pc1 series was still intended for them, but it is not certain that the locomotives have been redrawn, as the official type list of the Polish Ministry of Transport from 1927 does not contain this series. According to some sources, the last three locomotives were in service until 1931, but this is unlikely.
The Lithuanian state railway Lietuvos Geležinkeliai (LG) took over a locomotive that was classified as the K1 series (also known as J1 ) with the number 901.
The vehicles of the second series were a Tender (classified in Poland as a 12C11) of the type 3 T 12 is provided.
