TheRenfe Class 311 is a class of four axle Bo'Bo' diesel electric shunting and light freight locomotives.
The prototype locomotive311.001 was designed by M.T.M. (Barcelona), Ateinsa (Madrid) and Babcock & Wilcox (Bilbao); the project was led by theInstituto Nacional de Industria.[note 1]
The prototype locomotive led to an order of 60 units, which were assigned to the subclass311.1, and numbered 311.101 to 311.160.
The transmission system uses 4 axle hung pinion drive three-phase asynchronous motors powered by a three phase alternator driven by aMTU engine partly license built byBazán. Siemens supplied Sibas-16 microprocessor engine control systems.[3]
The prototype locomotive was initially painted orange with a white stripe, the series production were all given a red/silver livery; standard for Renfe shunting locomotives. Some units have subsequently received a more recent white/grey Renfe livery. As of 2010 most of the units are operated by Renfe Mercancías, about one third have been assigned to the infrastructure companyAdif.[4]
The locomotives were a success for the Spanish engineering industry, and the design formed the basis of a number of locomotive types exported from theMeinfesa factory: theSBB Am 841 (40 units 1994), theGA DE900 locomotives for Mexico, Israel and Egypt (35 units, 1997-2000) and theSNCF Class BB 60000 (175 units, 2004-8).[5]
