Czech State Rwy 4-6-0 Locomotives in Czechoslovakia
Class Details by Steve Llanso of Sweat House Media
Class 364.2 (Locobase 1645)
Data from A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot:David & Charles, 1966), supplemented by Google translation of Czech Atlas website at [

These were rebuilds of the kkStB 209 & 309 (Locobases 470 & 1197, respectively), which had been delivered to the ONWB in 1904 as four-cylinder compounds (209) and thre-cylinder compounds (309).
In recasting them as two-cylinder simple locomotives, Czech designer Ludvfk Schejbal also added a moderate amount of superheat. The result proved to be both efficient and economical.
After their reconstructions in 1930-1933, the class all survived the Second World War, being retired late in 1940s and early 1950s.
