CAF Bitrac  
In October 2007, the Spanish manufacturer Construcciones y Auxiliar de Ferrocarriles (CAF) published first information on a new locomotive concept: the Bitrac. The Bitrac is a two-engine diesel-locomotive with additional equipment to run on 3kV DC catenary systems. Like many other locomotive solutions, the Bitrac is presented as a flexible platform. CAF has published information on two basic versions; a four axle locomotive with 300 kN starting traction effort and a six axle version with 440 kN. Of course, the final specifications of Bitrac-products depend on what the market requires.

As a diesel locomotive, the Bitrac produces 2x1800kW (engine output, power wheel at rim is appr. 2900kW in total). Under the 3kV DC, is has 4450kW duration power. - CAF

CAF Bitrac: Fesur - launching customer  
First customer for the Bitrac was Ferrocarriles del Suroeste SA (Fesur) from Spain. It is an open access operator, founded in 2007. Both Grupo Alfonso Gallardo and Gea21 own 50% of the shares. Jerez de los Caballeros (Badajoz) is the home base of Fesur. In 2008 it got a license to operate its own rail services. CAF built nine Bitrac BITRAC CC35600 for Fesur, being the launching customer for this platform.

The homologation of the Bitrac locomoties was directed by rail operator Comsa. ADIF, the Spanish rail authority granted the Bitrac with a full approval in 2010. Early 2011, CAF delivered all nine machines to Fesur, but the company never operated them (see news for more information). All machines were returned to CAF, the last six of them arriving there on 21.02.2012. CVS (Compañía de Vagones del Sur) should have delivered 400 freight waggons to Fesur, but this contract was abandoned.
