Based on the Allhallows-on-Sea branch, which ran from Stoke Junction to the Kent coast and opened in 1932, it was operated by the Southern Railway. British Railways (Southern Region) absorbed it into the nationalised framework in 1948.
Terry has produced a superb model which depicts the branch very well and with atmosphere.
The following photographs give some idea of the project. Terry has been delving deeper into the archives and the latest image of the track plan, and the control panel further down, depict the layout as at 1954.
Even earlier a 1953 "innovation" appears at the foot of this page with an ACV Railbus in manufacturer's livery.
