I've setup a similar system for my layout.
Only all the trains go in one direction.
I used a One-direction Power Cable on the main track.
and either a One-way Power Cable 'A' or 'B' for the holding area.
The only issue I have is that the sensors need a timer for my main stock to exit the holding area.
It's ok for Mult-units, like the 103, HST and such.
But freight trains or any trains with different shaped wagons and such don't quite work.

I am not sure this helps, but this video shows what I think is a cool setup.
