Have you read Keith Lowe's book, "Tunnel Vision"? It's quite funny, and
well researched.

It's going second hand for just £1.44 from a seller on Amazon

I bought it for a quid a few weeks ago from the bookshop in the Mall at
55 Broadway (St James's Park tube), he seemed to have loads of copies,
worth a try to see if any are still in existance.

I didn't think the two lines shared at all (strictly speaking).
They've got their own tracks and platforms at the shared stations (eg
Wembley Park, Finchley Road). So, although the two run parallel for a
while, I wouldn't say that they shared, as such.

They share a route, but as you say they don't share actual tracks. A bit
line the Piccadilly/District in west London.

do the Jubilee and Metropolitan Lines share tracks between Baker
Street and Finchley Road?

No, the Jubilee is in a tube tunnel, and the Metropolitan is in
traditional surface/cut-and-cover.

As far as I recall, yes. At Baker Street the Jubilee (was once part of
the Bakerloo) is in a tube tunnel, and I don't think the lines merge
until Finchley Rd. Even then, they stay as two pairs of track, each
dedicated to one of the lines.

I thought that the Met was in one or two tube tunnels for some of the way,
although it seems to be cut and cover at the airhole in Swiss Cottage.

The Met is certainly in two tunnels for some of the way; presumably
these sections are bored rather than C&C, unless there's a reason I've
missed why it would make sense to have twin cut-and-cover tunnels.

I believe the technical term is they share a "formation".

Getting a tad pedantic.

The Met goes over the Regents Canal, but most of the rest is in tunnel.
Some of it may well be bored.

But there are crossovers which allow trains some interchange between the
tracks of the two lines.

Weren't these removed sometime in the past few years?

Possibly. They still exist on the District/Piccadilly between Acton Town
and Hammersmith/Baron's Court.

I noticed last week that the down (does LUL use up/down) Met - Jubilee
crossover at Finchley Road is incompletely but functionally removed.
Can't comment on the others.
