Abstract
A railway traction vehicle, in particular a locomotive, is provided for pulling at least one coupleable railway car, which may be a two-level car, having a car body with a car roof which defines a car height. The locomotive includes a vehicle body with a vehicle roof which defines a vehicle height. If the vehicle height is lower than the car height, a roof transition element is disposed on a rear-side end region of the vehicle body. Since the cross-sectional profile of the roof transition element expands from the front edge, which follows a contour line of the vehicle roof, to the rear edge, which follows a contour line of the car roof, the flow resistance in the transition region from the locomotive to the subsequent two-level car is reduced in a simple way, so that traction energy losses and vehicle noise can be reduced.
