With Newcastle for example, trains coming off the auto section would
approach the Accept Signal which would give them authority to enter
Newcastle Interlocking area. This applies throughout. Basically trains
can enter a Double Line area without a request from the signal box in
front but then they'll approach it's Accept and that will give them the
authority to enter.
