Maurie,

what on earth do you hope to achieve in the way of safety by barring running crosses.
It merely transfers the point of impact from the side of the train to the front. In
fact it could be argued that with running crosses it might be potentially safer
because you might just miss the other bloke. If a train is going to run through a
crossing loop (on either line) out of control then it is going to hit anything in the
next section unless it can be pulled up in time but that is not going to save a train
waiting at the opposing arrival home signal.
