TheClass 340 ofRenfe (4000 under the previous numbering scheme) were a class of 4-axlediesel-hydraulic locomotives built byKrauss-Maffei (andBabcock & Wilcox) for the Spanish Railways. The design is similar in outward appearance and technology to theDB Class V 200. 32 units were built.
The locomotives had a total power of 4,000 hp (3,000 kW) from 2 motors (each a 16-cylinderMaybach/Mercedes-Benz MD870) diesel engine. Hydraulic transmissions used were twoMekydro K184.
The contract consisted of a series of 32 units which were shipped between 1966 and 1969, ten manufactured in Germany by Krauss-Maffei and the remaining twenty-two manufactured Spain by Babcock & Wilcox. The locomotives were similar to the V 200.1 Series of the Deutsche Bundesbahn, but with more power, more weight and slightly longer.
The units were conceived as locomotives for passenger services, with a maximum speed of 130 km/h (81 mph), but then were also used for freight trains which together with inadequate maintenance led to many failures in this series.
None are currently in service and 30 of the 32 units have been scrapped, the4020 (Renfe 340 020) is in theMuseo del Ferrocarril de Madrid[3] and the4026 (Renfe 340 026) is in the process of being restored by the AZAFT (Asociación Zaragozana de Amigos del Ferrocarril y Tranvías).
