The leading tripcock will only hit a trainstop if the signal is being passed
at red, not usually done.

The rear tripcock is on the wrong side of the track to connect with the
trainstop.

So is that to imply that there's no tripcock-equipped lines that are
signalled for bi-directional working? Or if so, is there some
technical gubbins that will lower the "wrong-direction" cocks when a
train is running wrong line?

TIA
