Have you seen Clive Feather's site, Davros.org? It has a lot of interesting information on it.
Clive will be familiar to you if you're a reader of the uk.railway newsgroup or the SimSig forums.
The link is: http://www.davros.org/rail/culg/
Enjoy!
Clive's UndergrounD Line Guides are a series of pages describing the London Underground system and the independent railways of the London area - the Docklands Light Railway and the Croydon Tramlink (neither is a part of London Transport, though the DLR used to be). Each line is covered on a single page.
