The Somerset & Dorset Railway Heritage Trust is a charitable trust of over 1000 members based at Midsomer Norton, part-way up the 1 in 50 gradient from Radstock to Masbury, which was the highest point on the the old much-loved Somerset & Dorset Railway. The headquarters is in the old station building, which also houses the gift shop, second-hand bookshop and ticket office. Initially the running line comprised a half a mile of railway, which is being extended towards Chilcompton, which will double the length of the line.
