The side guide wheels (3a,b) of the running gear, inside the region of the points, are retained on one side in a guide track for guiding and fixing the direction of travel, and on the other side, for the purpose of crossing the points intersection region, they can be vertically raised and then lowered again. The side guide wheels, during a curve, are kept in the guide track on the curve inner side, and raised and lowered on the curve outer side. |
