The branch line from Highbridge to Evercreech Junction had been the original main line, when attracting steamer traffic across the Bristol Channel had been an objective. It traversed a sparsely populated area, and when the marine connection ceased, only Glastonbury and Street in the centre of the route contributed any worthwhile income. There had been other, shorter branches, but these too generated very little traffic and they had all closed by the early 1950s.
