The loop line was singled on 31 January 1972. Most of the sidings were removed at this time and the bay platform (Platform 3) was reduced to the status of a siding. Two signal boxes – one at each end of the station – were closed and new colour light signals provided. These are controlled from a Panel Signal Box at Bristol Temple Meads, but an emergency panel is situated in the Station Supervisors office that can be used to control the line from Puxton Signal Box to Uphill Junction along both the loop line and avoiding line when there are problems with the normal signalling system.
