Abstract
Abstract In track surveying or correction apparatus, a measuring bogie with two flanged wheels running on the track rails. The wheels are transversely movable in respect of a carrier for a track surveying element which is to be kept at a constant distance from a selected grade rail. A remotely controllable drive presses the carrier against the grade rail by a drive which is connected with the carrier, on the one hand, and the flanged wheel running on, and in contact with, the other rail.
