If we can do all this underground in London, why can't we do the same in other parts of the country which the challenges are easier ?
It does seem that quite small schemes take unreasonably long times to progress, such as Tavistock. Other obvious links are cast aside such as Newquay - St Austell and Bradford Crossrail (where c700m separates two terminal stations) etc.
Is that because those are quite small schemes, or because they're in the South West? What
was the last big new railway infrastructure scheme in the South West?
Never-the-less it is a good question.
To answer it you need to answer other questions though:
1) What is the South West (Government region?, The South West Peninsula?,
GWR▸ &
SWT▸ franchise areas?)
2) What is big new infrastructure (Does electrification and Requadrification of Filton Bank count? Reading Station as it had a big impact on services to the South West?)
Those are excellent questions that I
had thought of, but decided not to complicate my post like I do too often! As you ask ...
I was thinking of the South West region being Gloucestershire, Wiltshire, Dorset and west thereof - so that's Bath and Bristol, Somerset, Devon and Cornwall too. Basically beyond the main London commuter-land (though I know we have some)! I considered mentioning Reading, but I decided it was South East [London outer] rather than South West.
In terms of "big new infrastructure" I was thinking of new lines / perhaps new curves, etc, as a minimum. So adding back extra tracks (loops, single to double, two to four) and upgrading to change from diesel to bimode trains doesn't reach the level I was thinking of.
I'm also thinking of new track / routes in daily use. So Worgret to Norden / Norton Fitzwarren to Bishop's Lydiard don't really count. Was the connection at Westerleigh that trains use north of Bristol Parkway new when the old Midland line was closed? Was there a new connection added in when Plymouth was rationalised to allow the Gunnislake train to carry on operating? But these both strike me not as improvements, but rather the side effect of rationalisations. The most recent thing that compares to these other schemes we've talked about was the
Westbury avoider line and that's a very long time ago ... my best attempt to answer my own question, but surely there's got to be something more recent?
