Burnham-On-Sea railway signal box set to open to visitors tomorrow Burnham-On-Sea Railway Heritage Group is opening the town’s replica railway signal box for visitors tomorrow (Tuesday, July 27th). The building – which is located near to the site of the original signal box in the town’s Old Station Approach – will be open from 10am until mid afternoon. The railway signal box was funded by fundraising and a National Lottery grant and it was launched in September 2018 alongside several other rail-themed items nearby. In recent years, other railway items installed in Burnham include a set of railway buffers, a station name board, a signal, an information board, and a rail-themed weather vane.
