MZOV/Oeste 0-8-0 Locomotives in Spain
Class Details by Steve Llanso of Sweat House Media
Class 040-2191 (Locobase 5964)
Data from [
], the web site of the Spanish National Railway (19 March 2004).
MZOV was the Medina a Zamora y de Orense a Vigo, which bought this sextet in 1881. The design was practically identical to those of the Tarragona, B, F except for a higher boiler pressure setting of 10 kg/cm2 and trailing three axles under the tender instead of the earlier two-axle tenders.
Even after their integration into RENFE in 1941, the class remained in Galicia at Vigo until the last of the class was retired in 1964.
