The town of Westerham was served by a branch line which left the South Eastern mainline at Dunton Green, just to the north of Sevenoaks. The line was closed under the Beeching cuts of the 1960's and now much of the track bed is buried under the M25 motorway.
Most of the Locomotives and rolling stock are of Southern origin and are mainly kit built. Buildings on the layout have largely been scratch built from a variety of materials, and are based on those which once stood at the station, hopefully making the layout look familiar to anyone who remembers the original.
