Railway Clearing House Map of London published by the RCH London 1915. Engraved by Emslie. On folding linen in 45 sections size 133 by 103 cm. Scale two inches to the mile. The lines are coloured to show the various operating companies and the names of the companies are also printed by each line. Heights are indicated by shading or hachuring. Covers an area from Rickmansworth across to Loughton in Essex in the north and from Weybridge to Orpington in the south. Also shows the various underground railways of London. Folds into original black boards with title on a Great Northern Railway label to the front. This might have been an office copy; a planned line linking Finsbury Park to Tottenham appears as a faint pencil line. There are a couple of small ink dots but otherwise the map and boards are in VG condition.
