There would be some merit in a Euston to Aylesbury Parkway service,

I rather like the prospect of eventually having two Euston-Milton
Keynes services, via Aylesbury and via Watford. But the public might
prefer a choice of London termini.

There would plenty of interchanges with the Met. And, Baker St is
very close to Marylebone. :-)

It certainly is which is good. If Chiltern continues to expand and
improve they will need more space for London bound trains.

Stick another deck on top of Marylebone, in a slightly St Pancras
style? You'd have to lift the roof a bit to fit them in, but not by
much. Or you could build them beyond the end of the shed, in a more
St Pancras style.

You'd have to sever Rossmore Road to make this work, but you know,
omelettes, eggs.

Or, of course, you could dive, and build some platforms in tunnel.

And sever the Regents Canal?

Underground locks.

At one time I thought a new ariel curve above Neasden to carry
services to Saint Pancras by way of Cricklewood might be an answer.
But St P. is now full.

Paddington is hardly an option. It is also well utilized.

People keep telling me Euston has capacity. Difficult connection to
make, though.

No: you build a curve from Northwick Park to South Kenton and divert all
Chiltern Amersham trains through it to Euston, and sell off the Chiltern
tracks from Northwick Park to Neasden.

No, use them for an extension of the Brent Cross light rail.

I had a bit of a look to see if there was such a thing as an underground
lock, and i couldn't quite find any, although i did find an underground
inclined plane:

Does anyone know of an actual underground lock?

No, but this might help. Depending on the required gradient on the tracks,
you could conceivably cross the canal on the near level, traditionally this
would have involved a swing bridge. However a 'drop lock' (or sump lock) has
been provided for the Forth and Clyde restoration to allow the canal to
effectively burrow under a road, the same could be done under a railway:

There's one in Manchester, near Piccadilly station.
