Abstract
An electromechanical device for sensing the center line of a track is disclosed. The track center line is previously marked out by a line of nails protruding upwardly from the ties and the center line follower is moved by engagement with the rails to right or left to derive an appropriate electrical signal causing operation of a ram carrying the center line follower in a direction to cancel the signal. A track operating device, such as a magnetic wheel for picking up tie plates from track that is being renewed, is disposed over each rail location and the top track operating devices are moved laterally conjointly with the center line follower thus to maintain the track operating devices at the correct lateral locations.
