When the circle line gets to Aldgate there is often
a delay of a couple of minutes, sometimes lasting
up to 10. Is this where the drivers change over?

I don't think so, but it is one of the few places where Circle Line trains
can wait without getting in the way of other trains, so short delays are
deliberately scheduled there to allow late trains to get back on schedule.
I'm not sure about the 10 minute delays though - since the line runs every 8
minutes, this sounds implausible!
