The leading tripcock will only hit a trainstop if the signal is being passed

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?

There are (as I said earlier in the thread) a few places on LU where
trains can go in either direction, terminal lines being the most
obvious. At these locations the "wrong way" trip levers will be seen
to lower as a train approaches to prevent rear-tripping. IIRC High
Street Kensington is such a place possibly with some short stretches
of bi-directional track on the southern approaches. The same possibly
also applies to the two through Met main line platforms at Baker
Street if they are still signalled to cope with reversing trains.
