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.
