A short wheel base bogie provides stability by using a double pivot arrangement. Wheels are mounted to walking beams on each side of the bogie. The walking beams are mounted for transverse movement relative to corresponding pivot frames. Upon the bogie getting to a curved track section, the walking beam moves transversely in order to maintain the bogie in proper gauge. The bogie is used for a rail grinder vehicle wherein rail grinders are mounted upon the pivot frames such that the rail grinders follow curves in the rails. |
