This is a device for transferring vehicles from one track to a parallel one without the use of a turnout or a crossover. It is quite a costly arrangement and is preferred only in workshops where space is limited and a coach or locomotive is required to be shifted from one shop to another on a nominated line.
A traverser (Fig. 27.7) consists of a platform with a track that is mounted on small wheels or rollers, which can traverse to and fro and can fall in line with the track on either side of the traverser. The following steps are involved in transferring a vehicle standing on track 3 on the left-hand side of the traverser to track 2 on the right-hand side.
1. The traverser is aligned with track 3 on the left-hand side.
2. The vehicle is then transferred to the traverser track.
3. The traverser is then shifted so as the align it with the track on the right-hand side.
4. The vehicle is then transferred to track 2 on the right-hand side.
