It comprises counter pressure rolls in front of and behind the drive wheel. The counter pressure rolls engage the surface of the upper flange which faces the lower flange. Several support rolls engage both sides of the vertical web of the rail. The bus bar is connected to the side of the vertical web of the rail facing away from the drive wheel.
