This Great Western branchline has undergone some significant changes over the last few years in order to enhance its operating potential. The layout was originally constructed as an elongated letter J with a shed, turntable and station approaches. This area survives but an extra three boards have been added making the layout 46 feet long. It is 2'6" wide. There is an additional 6 inch wide bolt-on scenic road section which fits in front of the station. Little of the original alignments remain although those who know where to look can see the nostalgic remains of the original tunnel, a plafform face and Brians bridge! The new station complex includes structures from the original layout including the signal box which is based on the one at Fairford station. New structures have been constructed on the platforms that conform to typical Great Western practice and a new carriage shed can be seen behind the up platform. The structure is based on the one at Helston. The larger station has required the signalling arrangement to be altered and amended. GWR pattern lower quadrant signals have been built from the excellent Scale Signal Supply range.
