Czech State Rwy 2-6-2 Locomotives in Czechoslovakia


Class Details by Steve Llanso of Sweat House Media

Class 354.7003 (Locobase 5862)

Data from [] (25 Jan 2004) and [], last accessed 11 October 2013.

These are the simple-expansion companions to the Austrian 429 class Golsdorf compounds. Obviously, the design satisfied Czech requirements, particularly after their reconstruction in 1926. That's the configuration shown in this entry. It was widely viewed as satisfactory except for the relatively meager superheated area.

The class later included simpled 354s of other subclasses and operated into the 1960s with the last regular run in 1970.


Class 355.0 (Locobase 1644)

Data from Google translation of Czech Atlas website at [], last accessed 20 October 2011.

Some of the Austrian 229-class engines taken into Czech service were refitted to take two domes in the mid-1920s. The upgrade didn't prove successful, so Ludvfk Schejbal took 5 in hand for a further makeover. He fitted the class with an outsized superheater and combustion chamber. Other changes raised the class's axle loading and limited its branch-line service.

The engines were placed in service in Moravia. When Nazi Germany took over Czechoslovakia in 1939, the DRG classed this quintet as BauReihei 75 901-75 905. After World War II, at least four of the engines continued in service until 1951-1952.


Class 365.01 (Locobase 1646)

Data from [], last accessed 3 December 2006. See also A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot:David & Charles, 1966).

The Czech site's photo shows a high-boilered Prairie intended for passenger service. Three variants are shown on the site, all of which had the same power dimensions (cylinders, driver diameter, boiler pressure) and firebox dimensions. See Locobase 7990-7991 for the other two.


Class 365.07 (Locobase 7990)

Data from [], last accessed 3 December 2006. See also A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot:David & Charles, 1966).

Sporting the largest boiler of any of the CSD 365 Prairies, this class was the middle child. See 7991 for the third sub-class.


Class 365.2 (Locobase 1647)

12 rebuilds of Hungarian MAV 322-class locomotives. Date is approximate.


Class 365.21 (Locobase 7991)

Data from [], last accessed 3 December 2006. See also A[nthony] E[dward] Durrant, The Steam Locomotives of Eastern Europe (Newton Abbot:David & Charles, 1966)

Sporting the largest superheat surface of any of the CSD 365 Prairies, this class was the middle child.


Class 365.3 (Locobase 1648)

18 110-class from Austria rebuilt with a "decidedly rakish" appearance. Date is approximate.
