The fourth volume covers the suburban network and the Mid-Sussex line to just north of Horsham. The South London, Crystal Palace, West Croydon and Epsom Downs branches are all in here.

The Tooting, Merton and Wimbledon Joint Line is included as is the line from West Croydon to Wimbledon.

This volume also includes addenda and corrigenda to volumes 1 to 3 plus additional drawings of Longhedge Junction, Willow Walk, Brighton, Selsdon Road and Grove Junction.

Finally there is a brief account by John on the background to the drawings and the B-series numbers used by the LBSCR.

If you are not sure whether the location that interests you is in this volume or a different one, a combined index of all the locations in the series can be downloaded from our main web site entirely free of charge.

This is an A4 card covered book with, generally, 1 diagram per page.
