I was wondering, as i was sat on it this morning, whether it would
be possible to construct a connector between the Bank and CX
branches around about Euston, so that they could act as two arms of


Not really, since it would have to miss Euston.
Not so! See my previous post with the ramble in it. Or not, if you prefer.

And, if you plot my details (which you quote) on a map, you'll find that
it's perfectly practical to run tunnels westwards from Euston (City)
that link into the CX branch before it reaches Warren Street. Well,
practical in plan; I don't know whether vertical separation would be a
problem or whether there are other issues (as well as cost, of course).

Why "delay-inducing"? The junctions are designed so that all possible
non-conflicting moves can be done simultaneously.
It was my understanding that although the junction is graded, there's
still interference between the lines.

True. It can be a problem for some combinations.

It's the big-metal-rolly-thing analogue of head-of-line blocking in
network switches, if you've come across that (not that i'm implying
you'd sully your hands with such link-layer trivia ).

Don't! I have a long-running argument going on with BT about SCTP
implementation or, in their case, misimplementation.
