- Where would you reverse? A stock can get to Aldgate East, but there
are apparently infringements at Whitechapel,

According to CULG, they're allowed on the District between Aldgate East
Junction and Upminster.

Also according to CULG, they're allowed on the H&C between Aldgate
Junction and Edgware Road! Does that mean that only the Aldgate Junction
to Aldgate East junction is banned (which contradicts the known use for
ELL stock moves), or does that description just reflect the way Clive's
divided the lines up?

My source is Tubeprune:

Who says "[A] stock is currently barred east of Aldgate because of
infringements at St Marys, Whitechapel, near Bow Road, Barking and
Dagenham". He also says in:

http://www.geocities.com/tubeprune/unstories.htm

"As there are some gauge infringements along the route, some work will be
necessary to allow the A Stock to run out there and the platforms will
have to be extended at Barking at least. The locations of OPO CCTV
screens and mirrors will also require alteration at most stations between
Aldgate East and Barking. Some signalling improvements will also be
necessary."

I don't know how much of this is still up to date.

Clive also says of the District "the Richmond and Wimbledon branches are
shared with NR trains" - Richmond, yes, but Wimbledon?
