Description
The typical London & South Western or London, Chatham & Dover Railway signal consisted of a lower quadrant arm on a lattice post, with a cruciform finial and round-case lamp, supplied by Stevens & Co. Post-Grouping, the Southern Railway modernised many signals by replacing the arm with the upper quadrant Westinghouse type (kit S7/KS2), but some remained in service almost to the end of steam days.
