Hi all,
I can't seem to get my head around the above aspect.
the definition i have is:
STOP, applies to the movements in the direction to which the signal can be cleared; other movements may pass.
im confused because only movements in the direction to which it can be cleared will see the aspect. the other movements will see the back of the signal.
thats my thinking but obviously i am missing something.
