First, many thanks to Albert Ball for his superb program and his continuing exhaustive help to new route-makers, such as myself.

This is the first released version of my attempt to re-create the complex triangular junction at Aldgate on the London Underground Network. Complex for two main reasons – the high-intensity of the service pattern and the fact that all crossovers are on level grade.

A look at the screenshot will show that trains approach from one of the three end points of the triangle which I have labelled ‘To Moorgate’, ‘To Tower Hill’ and ‘To Whitechapel’.

The service pattern is as follows:

* Hammersmith & City Line from Moorgate to Whitechapel: 8 minute frequency in both directions
* District Line from Tower Hill to Whitechapel: 4 minute frequency in both directions
* Circle Line from Moorgate to Tower Hill via the outside platforms at Aldgate Station: 8 minutes in each direction
* Metropolitan Line from Moorgate to Aldgate (either of the two centre reversing platforms) and back to Moorgate: 4 minute frequency.

The timetable is a vastly simplified version of the real-life WTT, with each route being repeated 20 times (which can be changed easily in the timetable editor if you are feeling masochistic!).

The track work is based on the Quail diagrams but again is simplified for ease of design. The positions of the signals is pure guesswork as I have no diagrams of the actual layout. For example, I am sure there probably isn’t as many signals on the District Line leg of the triangle between Minories Junction and Aldgate East. If anyone has access to the real-life signalling diagram please let me know!

I have included a session file which sets up the automatic signals prior to operation.

I am concurrently working on a simulation of the Earl’s Court area as well, but this is a much more serious proposition. Eventually it would be nice to produce a working version of the whole of the Circle Line, although I’m not sure it could be handled by just one operator even at snail-paced speed.

    Couldn’t get to any exits, won’t let me set a route to any exit.

      Hi Seggy224,

      On this railway it is necessary to set unrestricted (i.e. red) routes to each of the the exits. If these are used rather than preferred routes (green) then it will work OK.

    May i (whilst giving full credit to the keith) make and release a enhanced timetable reflecting the current workings?

    • Greetings,

      As long as you credit the author, and share alike (Creative Commons: CC-BY), I don’t see why not?

      Hey! Did you ever manage to release that version?
