ABSTRACT:
A rail forger for reforming worn rails is disclosed. The forger includes a mobile frame capable of travel along the railway and a pair of forging shoes pivotally suspended from the frame. The forging shoes are adapted to travel along either side of the rail and are shaped to conform to the desired rail profile. By periodically and simultaneously applying a force to each forging shoe, the rail is impact forged and returned to its desired profile. A resonant system comprising a pair of horizontally suspended resonant beams is excited by a pair of eccentric weights at the upper ends of the beams to drive the associated forging shoes at the lower ends of the beams against the rail.
