Class 523B 0-10-0T (1948)

Class 523B 2-Cylinder Shunting Locomotive
Designed by Frihdrik Tešlov
Built in 1948 by Krauss-Maffei, Munich, Germany

The post-WW2 locomotive building programme of Frihdrik Tešlov included of course engines which completely lacked glamour but were no less vital to the rebuilding of the RSR. Among them was this burly tank locomotive. Twenty of these engines were built by Krauss-Maffei in 1948 to supplement the surviving 433A 0-8-0s. The RSR had to handle immense amounts of goods in the early post-war years and the lion's share of it passed through the marshalling yards at Terešan and Belšinohra, where these engines had to divide and reform one goods train after another without a break. To enable them to stay out in the yards for long turns of duty, the 523Bs had storage for large amounts of water and coal and a big, deep ashpan to keep their grates clear. Apart from journeys to and from the works, these locomotives were confined to the yards. From 1958 onwards, the entire class were rebuilt as fireless locomotives, class 520A.

The original plate-framed design, to which the first three locomotives were built, is shown below. These engines became class 523BB.
