The Renfe Class 311 is a class of four axle Bo'Bo' diesel electric shunting and light freight locomotives.
Background and design
The prototype locomotive 311.001 was designed by M.T.M. (Barcelona), Ateinsa (Madrid) and Babcock & Wilcox (Bilbao); the project was led by the Instituto Nacional de Industria.[note 1]
The prototype locomotive led to an order of 60 units, which were assigned to the subclass 311.1, 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 a MTU engine partly license built by Bazán. 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 company Adif.[4]
Derivatives
The locomotives were a success for the Spanish engineering industry, and the design formed the basis of a number of locomotive types exported from the Meinfesa factory: the SBB Am 841 (40 units 1994), the GA DE900 locomotives for Mexico, Israel and Egypt (35 units, 1997-2000) and the SNCF Class BB 60000 (175 units, 2004-8).[5]

Notes
^The locomotives are sometimes known as Mabi from the initials of the companies involved in the design of the locomotive.
