Work is underway at Polegate level crossing in preparation for the controls changing once the signalling is relocated.
At the moment the signal box at the station, which could be demolished, controls the signals locally but the controls are moving to Three Bridges under a scheme by Network Rail.
A team of workmen has been at the Polegate site since the early hours of Monday (October 21) to place in new electric equipment and the crossing will be closed to drivers until 5am next Monday (October 28). Trains are still running at Polegate Railway Station.
The historic signal box building is not listed by English Heritage but many people in the community do not want to see it demolished.
Network Rail has said those people have the chance to highlight ways it could be used after its days functioning as a signal box end.
A spokesman for Network Rail said, “As part of the modernisation of signalling on the railway which is taking place across the country, the signal box at Polegate will not be needed when its operations are transferred to a new signalling centre at Three Bridges.
“We are in discussions with the local authority and local people about whether the box has an alternative use within the community.”
The Save our Signal Box campaign group organised a committee meeting last month to discuss the issue.
