These pages contain various signalling information and are designed to give some
background information into the way signals operate and the way that you see them
behave when out on the road. Don’t expect anything too detailed. The aim is to try
and keep things as simple as possible to make things easy to follow.
The files are generally in the form of a set of notes with explanatory diagrams,
some of them going through a process step by step. In some cases, an animation is
available as well as the notes.
The notes are in PDF format and the animations are in ShockWave
These animations look fine when I view the site on the internet, but there are some
problems when viewed via the LUL intranet - I don’t know if this is common to all
computers connected to the intranet or not or whether it depends on the software
used to view the files.
The files will run, but the colours do not always show correctly. E.g., the signal
posts are red instead of black and some track circuits show up as red instead of
blue or black. The colours on the accompanying PDF notes are correct. If anybody
knows the reason for this, then please let me know!

There are just a few files here at present, but I hope to increase these, covering
different aspects of the signalling as I get the time.
