and ticket signalling system. This ensured that only one train at a time was on each end of the line; a loop at Orwell allowed two trains to pass. An additional section was created between Felixstowe Pier and Beach stations when the latter opened. Tyers Electric Train Tablet was in use on the line by 1891 and trains could pass at Felixstowe Beach. An additional passing loop came into use in May 1891 when Trimley station opened, and another one was created at Derby Road in November that year. Signal boxes were provided at every station and at Felixstowe Dock Junction which was the boundary between the branch and the lines of the dock company. This was closed in 1928 and replaced by a ground frame. When a train ran down to the pier it needed the signalman from Felixstowe Beach to accompany it to operate the signals. In 1969 the section from Felixstowe towards the dock was converted to staff and ticket working so to provide more flexibility to cope with the increasing number of freight trains. The remodelling of Felixstowe in 1970 saw the closure of Felixstowe Town Signal Box, the electric signals and junction with the line to Felixstowe Beach being operated from Trimley. The passing loop at Trimely was taken out of use in 1986 when it was altered to become the connection to the Port of Felixstowe's new branch line. In 1999 the remaining signal boxes at Westerfield, Derby Road, Trimley and Felixstowe Beach were closed, control of the branch being transferred to Colchester Panel Signal Box. Colour light signals and motor-driven points are fitted throughout, while level crossings at Trimley and Felixstowe Beach are monitored by CCTV. Signal passed at danger (SPAD) indicators were fitted at several places to act as a warning to drivers should they pass a red signal.
