It puzzles me that LU insists on running Met Line trains thru to
Aldgate. The Junction there must be an operating challenge. Meanwhile
there is ample unused capacity at Moorgate. Surely the walk saved to
City employment centers cannot be so much shorter from Aldgate?


I just tried the trip between Moorgate and Aldgate in
http://journeyplanner.tfl.gov.uk/user/XSLT_TRIP_REQUEST2?language=en
and found it takes 4 minutes by LU and 18 walking.
I regularly make that walk. I would be quite uncomfortable to share some
parts of the footpaths with many extra pedestrians. In fact, people
transfer to Circle trains at Barbican when trains teverse at Moorgate.

Reversing at Moorgate means eastbound trains cross the westbound line to
a single reversing platform.
At Aldgate, there are two reversing platforms between the east and west
bound lines.
Reversing at Moorgate is uncommon. I assume it only happens when there
is unusual congestion around Aldgate.

If Crossrail ever happens, things will be more interesting as Moorgate
and Liverpool Street will be one station - the trains will be long.
