And what makes you think the train coming towards it had not been
stopped as a result of the erroneous train occupying a track circuit (in
that sense "ahead of the correctly routed train")?

Just curious; I haven't seen this detail discussed, have you?

The question I hinted at way back was whether there would be any
signalling or tripping affecting the wrong-way train.

I assume a train going the wrong way will activate track circuits just
like any other train.

Obviously, being on the wrong track was something that the driver was
likely to notice,

And if not, why all the palaver abut drivers needing route knowledge
(yes, Tom, even in the dark).

but would the right-way train, stopped by a red light and
occupying the track ahead, make any difference?

Not to the train going the wrong way. But hopefully the right-way train
would not get a green signal, leaving the wrong-way train ages to
discover their circumstances (for example, not having passed any signals
that were intended for them, even if they couldn't see from the
surrounding context that they were wrong-way).
