Caile Ferate Romane 0-10-0 Locomotives in Romania

Class 50 (Locobase 5299)

The CFR chose the Prussian G10 design as the standard freight engine for the newly established Romanian national railway system for several reasons, according to Romania's Aldo Travel Agency website ([], visited 9 December 2002). Perhaps the most important was that its boiler was interchangeable with those of the 230-class 4-6-0s, which were based on the Prussian P8.
In all, 285 locomotives came from German builders. Beginning with 50.243 in 1926, dubbed "Regele Mihail" after Romania's then-reigning king, the Resita works turned out 266 over the next 18 years. Malaxa Works in Budapest contributed 254 from 1928 on.
This was the most numerous class on the CFR.
