Well that's the turn round time.

Indeed. But if systems in this country were run continental style it would
be one in - one out. As soon as a train terminates another heads off. But
for some reason we can't seem to manage that here except on the DLR. The
fact that that is computer controlled rather than relying on drivers probably
says it all.

That's to balance out the headway south of Dalston relative to the
headway between Highbury and Dalston. This may change when the service
goes up to 16 tph (on the core) in December.

But its all the same line. Why does it need to be balanced when its only
gone a mile down the line? Its like the nonsense at arnos grove on the
piccadilly line.

The Overground seems to have quite relaxed schedules so as to give
recovery time and ensure high performance levels.

I wouldn't call 20mph high performance. Its not just the frequency of trains
that matters, its how fast you get to your destination once you're on one.
