Note
This needs a much better picture

This is a pre-signaled modified cloverleaf, with the possibility of U turns on special tracks. It's based on the Advanced Main Line Depot which uses pre-signals to give priority to the trains on the main line. The exits from the mail line are before entrances, reducing traffic problems (Fig.1).

Pros:

  • Traffic jams less likely.
  • Can handle a large number of trains at a time.
  • Exits from main line are before entrances, reducing the chance of traffic problems.


Cons:

  • Very costly to build.
  • Trains must slow down to climb a slope.
  • Trains must slow down during sharp turns.
  • Trains must turn left to turn right. This could lead to trains getting lost. (Can be fixed by using waypoints).
