The minimum radius for operation is 360 mm / 14-3/16". The car has low-mounted entries between the trucks. It also has factory-installed LED interior lighting on both levels and an operating current-conducting close coupler on the end of the car without an engineer's cab. The car has a lighted train destination sign on the end of the car. The interior lighting and the train destination signs on the sides of the other bi-level intermediate cars can be turned on and off in digital operation by means of a decoder in the cab control car. A defined car order is specified to do this. The triple headlights and dual red marker lights change over with the direction of travel and can be controlled digitally. Long-distance headlights can also be controlled digitally. The headlights / marker lights changeover, interior lighting, and the train destination signs on the sides will work in conventional operation. By removing a piece of skirting, a normal coupler can be installed on the end of the car with an engineer's cab to allow a locomotive to couple to that end of the train. The end of the car without an engineer's cab has transparent red marker light inserts. The car has prototypical Görlitz design trucks.
