Czech State Railways 0-6-2 Locomotives in Czechoslovakia
Class Details by Steve Llanso of Sweat House Media
Class U37 (Locobase 7992)
Data confirmed from [
], the Czech website.
Some confusing numbers for these engines that appear to be based on the U class of the Austrian State Railways. For one thing, the total evaporative surface seems to include the firebox surface added in twice. The other is a total engine weight almost double that of the Austrian engines.
