チェコスロバキア国鉄
The Czechoslovak State Railways (CSD) was one of the largest tank locomotive users in Europe. The dense railway network in Bohemia and Moravia provided the ideal environment for local short distance passenger train workings powered by numerous classes of tank locomotives. On 31 December 1937, the CSD had no less than 1,250 tank locomotives on its roster, of which 385 were eight-coupled tank locomotives.
