Just use that information to decide whether or not to open the doors

Until a security alert closes a station so the train doesn't stop there
and then the count is off by one.


So how does it keep the count of "The next station is..." displays updated
when that happens?

I don't think it does. My mother was travelling on a train from Clapham
Junction to Arundel; I don't know what had gone wrong, but the train she
was aiming for was cancelled, and the following train was only 4
carriages, not 8. As you can imagine, it was packed out, but luckily
someone gave her their seat, so she was all right. Anyway, she told me
afterwards that the electronic displays thought they were going to
London, not away from it, so that "The next station is" was totally out
of phase with reality! She said it was very funny.
