Index and Key to Signal Diagrams

By Roger Mather

Roger Mather has produced some excellent signalling schematics of various line sections of the Underground as a reference source for visitors to the Tubeprune website.  They are believed to be correct as at 10 December 2002.

Click on the name of the diagrams for the two lines that are presently available, the Northern Line and the Victoria Line.

This page shows the key to the symbols used in Roger's diagrams.
