When placed on the track the cars look fine. But when you move them or drive them, interior seats appear outside the vehicle. Pasengers will also be loaded onto these very dangerous looking seats. This problem is common to all DLS models and seems to appear on only one or two vehicles in a set. If i delete those vehicles the seats reappear on another car. I have a screen shot but don't know how to attach it. I'm disappointed because my country route needs a railcar.
