I understand the layout of those switches. My response was addressing a poster's proposed changes to the current service pattern which would involve trains crossing paths, NOT the current service pattern itself. Regardless, No matter how the switches are set up, when a train on track B has to get to track A while a train on track A has to get to track B, all the while through service that remains on BOTH tracks A and B respectively is mixed in...it is a bad idea.

(Pretend there are switches in the middle of the two tracks and you are running the following services - 1,2,3,4).
1,2 ===========
3,4 ===========

A service pattern such as this one would never work, because of the delays it would cause:
1,2 =========== 1,3
3,4 =========== 2,4

That is EXACTLY what would happen at West 4 should the idea of "swapping" the South Terminals of the C and V actually occur: Delays.

Now I understand that the switches at W4 would allow the following service pattern to work without actually disturbing things:
1,2 =========== 3,4
3,4 =========== 1,2

..But that is not what was being proposed by Wallyhorse, so I didn't address it.
