This diagram shows the current signalling arrangements of the Waterloo & City Line. Despite now being a London Underground Line the signalling shows traces of its British Rail origins.

Most of the diagrams are in PDF format and to open them you will need Adobe Acrobat Reader. If you do not already have this it can be downloaded from the Adobe Website.
