Signalling
The signal box that controlled Friary goods and the junctions with the harbour branches was replaced on 1 July 1981 with two new boxes. "Friary A" was a 55-lever box at the junction of the passenger and goods lines on the approach to the station. A new 43-lever frame was installed in 1909. The box closed on 24 April 1966 when control of trains at Friary became the responsibility of staff on the ground, with the approaches controlled by the panel signal box at North Road.
"Friary B" signal box housed 45 levers and controlled movements within the passenger station. It closed on 21 July 1962.
