Not to change drivers, but to allow them a natural break. Remember that on
other lines, that run end to end, drivers get a few minutes break at
reversing points, which is not the case on the Circle. So a few minutes R&R
is allowed for at Aldgate.

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?
