There are standards mandated for signalling systems. However it would be
crazy for them to mandate one manufacturer's solution. It would be a
licence to print money. The real issue is about the extent of or
requirement for interoperability between lines. Apart from the sub
surface railway the only places where this routinely happens is Met and
Picc west of Rayners Lane and west of Acton Town. All other interworking
is for emergency purposes only.

Come to think of it, can trains be rerouted in this fashion anywhere
else?

I think there's some flexibility out west where the Picc and District run
together, BICBW.

You are correct. It also exists for the Met and Jubilee Lines at present
and as I have mentioned above.

I don't know whether a Picc train would fit all the way round. [...] I
imaging Aldgate might be a little exciting with a train of 73 stock

So is the tube (or at least the Picc) loading gauge or kinematic envelope
or whatever the kids call it these days not strictly smaller than the
SSL's?

*looks it up*

Ah, no, TS73 is narrower but longer than C stock, so given a tight enough
curve, it will hang further out over the edge. Presumably, that means
current D stock also wouldn't enjoy going through Aldgate much.

Without knowing the details that was the basic point I was making. 73
stock carriages are long and I suspect they may struggle with the circle
line platforms at Aldgate. Don't know about D stock.

This is a relatively old map, and it's also quite a strange map since
it's somewhere between the "London Connections" and the "Tube map",
showing the Croydon tramlink, Thameslink and Crossrail but not other
railways.
There's a few things that are definitely not going to happen.
Shoreditch is closed and will stay closed, the West London tram is very
unlikely, and the East London Line will be named Overground.
The Northern Line will hopefully be split by then, the Bakerloo
extended back to Watford Junction and the old Watford station would be
closed. Those are all much more likely projects than some of the ones
on this map.

Also there is no reconfiguration of SSL i.e no Met to Barking and no T-Cup.
No Wood Lane or renaming of Sherperds bush on the H&C
Shows Eurostar at Waterloo which is not going to be true

looking good? criticism welcome

Do you have the fares guide that'll go with it? That'll be a beauty.
