Can anyone point me in the direction of a book or other publication which
shows the track diagrams for Londons trams, in the way that Quail does for
railways?

Thanks

select the London 1935 layout. This runs on Bahn which is available
from

If you're not familiar with Bahn, it's kinda like a virtual trainset.
You should definitely try it - it's so addictive and you can get HUGE
layouts (like the entire NYC Subway).
