For traffic on routes that are not fully electrified, DRS ordered ten dual-powered locomotives from Vossloh España (today Stadler). Under the overhead line, they deliver 4,000 kW and the diesel engine delivers 710 kW, which is more than conventional electric locomotives with last-mile function. They are based on the UKLight, which is in service as class 68 and have 70 percent common parts with it. At first glance, they can only be distinguished visually by the additional pantograph. The engine here is a smaller Caterpillar C27 with only 27 liters displacement from twelve cylinders. DRS remained the only customer of the Class 88. The locomotives are mainly used to pull freight trains, but often also to pull passenger trains.
