was west of the level crossing on the south side of the line. In 1997 this signal box was closed, control of the branch being transferred to Colchester Panel Signal Box. Colour light signals and motor-driven points are fitted throughout, while the level crossing is monitored by CCTV. A signal passed at danger (SPAD) indicator was installed on the platform to act as a warning to train drivers approaching from Felixstowe should they pass a red signal. From May 2019 the infrastructure layout at Trimley was altered in connection with the partial doubling of the line towards Ipswich to accommodate more freight traffic. This meant trains from the Felixstowe direction could access the disused platform line (although this was not re-opened) and then two tracks extended westward for just over a mile to Gun Lane Junction. Both lines are bi-directionally signalled. Description The railway to Felixstowe was built with just a single track, but when Trimley station was built a second track was laid to allow trains to pass in the station. A platform was built for each track. The northern one (used by trains to Felixstowe) is nearer the village and so was provided with a single-storey building, also a small goods lock-up and a house for the station master. Two goods sidings were laid behind this platform. The southern platform (for trains to Ipswich) was provided with a waiting room and the signal box was built here, at the eastern end opposite the points for the goods sidings. People reach the station from the village along Cordy's Lane, which has a level crossing over the railway at the west end of the platforms. The loop was severed at the eastern end in 1987 in order to provide a connection to the new line to Felixstowe North Freightliner Terminal. Because of this the westbound platform was taken out of use and passenger trains in both directions now use the northern platform. Services , the typical Monday-Saturday off-peak service at Trimley is one train per hour in each direction between and . Trains are operated by Greater Anglia, and are typically Class 755. Proposed developments In 2009 Network Rail proposed to demolish the empty station building. A 'Friends of Trimley Station' group was formed and Network Rail agreed that they would leave it standing if a viable use was found for it. Suffolk Coastal District Council asked the local residents
