This signal box is on the other side of the road to the railway station at March. This box is still open in (2013) It is built in brick and is built high, so as to give a good view of the station and the goods loops and yard to east of the station.

It controlls a set of lifting barriers on a busy road and points and signals.

This signal box was raised to its present height in 1897, and it has 61 levers. This box took over some of March West signal box area, when that box was closed in 1987. At that time the frame of this box was relocked so it could take over March West signal boxes points.

In 2020 this box is set to close and March together with the Peterborough to Ely railway line will be controlled from the Anglia Regional Operations Centre at Romford. (if all goes to plan and time?)

During 2012 the East Jn (Junction) signal box had a make over. The box has had new windows and a new part on the rear. The wooden steps had new wood fitted as and when required.
