Well, yes, it *can* hurt. If you are running a service at 2-minute
intervals, then an extra 30 seconds means a 25% increase in headway,
which means a 25% increase in the number of passengers waiting at the
next station. At busy times, that will increase the dwell time at the
station, which then increases the number of passengers at subsequent
stations even further, which then increases the dwell time even further,
and so on. Are you seriously suggesting that you should get priority
over the many hundreds of passengers that would be delayed by holding
the trains especially for you?

I see your point, but it's just like it's done to annoy. Is it not possible
for the schedules be planned in such a way as to meet incoming City branch
trains - at least for the Charing Cross trains that actually start from
Kennington?
