Aldgate Delays
 

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!

Ok. Let's say up to 5 minutes occasionally. I only use the Circle line on
the times when the Northern line is scuppered.

Driver's don't change there but trains are timetabled an extended stop to
allow some recovery time as they're the only trains to use the two outside
platforms (normally) and they're the only platforms the Circle doesn't share
with either the Hammersmith & City or the District.

I always find it amazing that waiting 10+ minutes for a circle line is
not abnormal when they run an 8 minute frequency. The number of times I
have stood at Liverpool Street for 5 minutes or more waiting for any
train when there are three services all running a better than 10 minute
frequency! Must be like buses!

I *thought* they had dedicated platforms at Gloucester Road, too?

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.

Only one, on the Outer Rail.

That waiting was nicely explained in an excellent little book "How The
Underground Works" by P E Garbutt - my p/b copy, printed in 1966, cost
5/- new (IIRC, there were later editions) - on p.68.

Interworking with other services fixed the Circle line interval at 7.5
minutes, and minimum running time was 47 minutes per lap. In order to
fit a whole number of trains in, a lap was scheduled at 7 * 7.5 = 52.5
minutes, and so 5.5 minutes had to be lost somewhere. Aldgate was one
of the few places at which time could be lost without holding up other
services.

I used to catch an afternoon train into Waterloo, and then an outbound
one, not very long after, from Liverpool Street. So, during the week,
connection was good by Drain to Bank; but on Sunday, it seemed best to
use Charing Cross and Circle. The wait at Aldgate was always a source
of concern.

Probably the details have changed since I used it.
