Steam locomotive series 555.0 of the Czechoslovak State Railways. Drive on two axles of the tender and via a cardan shaft on all five driving axles of the locomotive. After the war, a total of 185 machines from the German steam locomotive series 52 remained in what was then Czechoslovakia. The locomotives were integrated into the fleet of the local state railway CSD as series 555.0. During their years of service and with the delivery of additional series, the heavy locomotives underwent modifications to an oil-fired main burner, which particularly made work easier for the locomotive crew. In 1973, the last CSD 555, 555.0259, was decommissioned. The crew quickly gave the locomotives the nickname "Nemka," which translates to "the German" and refers to the origin of the locomotives.
