But what you might find is if an AI train in the one direction detects the block is clear to an intermediate signal, it will be released from the crossing loop onto the single line even though another is already one coming the other way - rather than being held on the loop. On prototype routes signalled in this way I assume the interlocking logic is linked to the whole section and or exit from the next block post/crossing loop but I have my doubts the signalling in Trainz (or any other sim for that matter) is clever enough to do this properly.
"Stand off", then, on the single line rather than collision.
I'm only theorising so maybe experimentation is required. As I said in the other thread maybe it works if there are intermediate signals in both directions but overlapped slightly and even then you could only have one intermediate signal which still might not overcome the problem through really long sections.
Ultimately the whole signalling/AI/despatcher etc. in TRS is well overdue a thorough overhaul and we can only hope the programmers are looking at this for TS-X.
