So you're telling me they have no idea of which train is leaving
when? What do they do , just go and sit in a cab and wait until the
signal goes green then? Come off it.

The driver is much less interested in this subject than you are -- he's
not in a race with the other train, and doesn't really care which goes
first. So why would he do anything other than show up on time, and wait
till it's his turn to head down the tunnel?
