According to CULG, they're allowed on the District between Aldgate

so they'd have to reverse using
the trailing crossover which apparently lies just east of Aldgate
East; i have no idea if it's signalled to make that easy, and even
if it is, that's a reverse on a running line.

and drivers, which might not be available.

Yup, that sounds like it.

In another forum, someone has suggested that double-manning would
solve the problem - it certainly would in a 'actual safety' sense,
but since there's no problem in an 'actual safety' sense I'm not
sure how relevant that is...

It's relevant because you could have a Met driver with A-stock knowledge
and an H&C driver with the route knowledge, but the problem remains
where to reverse.

The issue is then whether the platforms east of Aldgate will take 8
cars, including suitable reversing points such as Whitechapel or
Plaistow.
