was that they'd use the 2 1/4 hours "spare" to traverse every
section of network. But we're not compring like with like here.
If they'd
used a bike on the regular Tube Challenge it would have *easily*
been
possible to knock a fair bit of time off the current world record -
probably
a good hour or so at least. This is why previous reecord holders
have done
it in apparently much better times (see www.tubechallenge.com for
more
info). So really there should be nearer 3 hours, possibly as much
as 4
hours "spare" to cover unvisited sections of track.

This simply demonstrates the issues of making up a new rule set,
when there's a well (and independently) established rule set
already.

True.

Still, it's just got me examining my best (so far) "all stations"
route
(theoretical though, haven't yet tested it) and working out what
sections of
line I haven't done. Should be quite easy to do most of them just
by means
of slight alterations and the occasional double-back, without
affecting the
route in too big a way. Mind you - in connection with that -
here's a
question - 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.

Right, ok. So it's at Finchley Road, where they both go overground,
that they both start sharing, right?


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.
