DRS says a comprehensive test programme will take place at Velim over the next three months before the locomotive is returned to Valencia for final preparations for delivery to Britain, which is scheduled for the second quarter of next year. The second locomotive, which is undergoing tests at Albuixech, will be delivered to Britain early next year.

Vossloh has specially adapted its 160km/h mixed-traffic EuroLight design for operation in Britain, working in conjunction with DRS and Beacon Rail Leasing on the project.

The 2.8MW diesel-electric locomotives are equipped with 16-cylinder Caterpillar C175 engines and advanced ac drive traction systems from ABB.

DRS has ordered 15 of the locomotives, which are due to enter service from the end of next year, and the contract includes options for additional units.
