Bulgarian State Railways 2-10-0 Locomotives in Bulgaria


Class Details by Steve Llanso of Sweat House Media

Class 14 (Locobase 5669)

[] (viewed 18 July 2003) shows us the data for the locomotive that [] describes as "...the definitive German 2-10-0. Stripped down, this is essentially what became the class 52 Kriegslok." Even in its original state, this engine had a markedly lower axle loading than the Class 44. Trifonov's data shows a smaller superheater than that of the 50s described by the german-railways.com site. Tube diameters are inner dimensions.

Trifonov's tables show us the variety of manufacturers that contributed to the 50-locomotive batch that the BDZ began procuring in 1942. Overall, the numbers sorted out as:

Borsig, Berlin 1

Esslingen 1

Floridsdorf (the Austrian state works), Vienna 10

Henschel & Sohn, Kassel 15

AWR-Jung, Jungentau 1

Krauss Maffei, Munich 7

Krupp, Essen 5

Schichau, Elbing 2

Schwarzkopff, Berlin 5

Skodawerke, Pilsen 2

These ran for more than 30 years in the Plovdiv division pulling both passenger and freight.
