Alternatives to HS2?
Sure, there are a few, but most come with flaws.
Avoiding central London is certainly an interesting idea. Maybe the route could avoid central Manchester and central Birmingham too?
I’m all for cross-London services (Thameslink making Gatwick and Brighton accessible to those from the north of London, Crossrail making Heathrow/ Docklands/ Stratford accessible to those from the other side of London). Crossrail 2 sounds a good idea (though there’s diminishing marginal returns with such things, I guess).
I can’t see that working on HS2 so easily (partly because you’d struggle to have eighteen services an hour unloading/ loading on the through platforms of a central London station – especially trains with end-doors like HS2 will presumably be – it’d be a little easier to do with 700s).
But actually avoiding the capital altogether? That’s niche…
One of the big problems with HS2 is that the cost gets disproportionately expensive at the Euston end, but the idea of terminating everything at Old Oak Common seems a bit too “RyanAir” (dumping everyone a long way from where they want to actually get to). With Euston Square being integrated into the current Euston underground station, plus Crossrail 2 on the cards, the connectivity of Euston will be rather fantastic. So, it’ll cost a lot of money, but if we want 400m trains terminating at somewhere in central London with good connections then what alternative is there? (I wonder if anyone will get their crayons out and find a solution that involves a station in the unused Aldwych branch of the Piccadilly line?)
Or, you could argue that the benefits of each mile of HS2 are disproportionately lower the further you get away from London. We could just build it from Euston to somewhere around Tamworth, so that London – Manchester/ Liverpool/ Glasgow/ Holyhead services can run non-stop that far out of the capital, and avoid clashes with the London – Watford – Milton Keynes – Northampton - Coventry – Birmingham corridor. That would have some merits. Maybe an ECML equivalent from London to somewhere around Grantham (with a stop at Stansted/ Cambridge)? A GWML equivalent from London to somewhere near Didcot/ Swindon (with a stop at Heathrow)?
Or, instead of creating capacity on existing lines by removing the non-stop 125mph stuff, you could look at creating capacity on existing lines by removing the 60/75mph freight onto a dedicated line (e.g. one line doing Channel Tunnel– Daventry – Mossend and one line doing Southampton - Thames Estuary – with a junction, lorry park and marshalling yard somewhere near the M25 – wouldn’t have to be a straight line, could be built to cheaper standards – wouldn't need to go through any existing towns - no expensive stations to worry about - could free up a few paths on some “shared” lines).
The above are just a couple of suggestions for “alternatives” that I could at least debate about (not saying I agree with them, just that they are at least something reasonable). What I can’t simply accept are…
1 …just do something more cleverer with the signals and make the timetables “intelligent” and find lots of spare paths that way…
2 …make everything even longer on existing infrastructure (we already have eleven/ twelve coach trains on the WCML, we are about to get 260m long IEP on the ECML – there comes a point when existing platforms can’t be extended any further without fouling junctions and causing signalling problems – there are lots of stations that are underserved because they are on fast lines where trains don’t stop very often - we need something better…
3… “just rebuild the GCR and stick to historic alignments” (please no)
Give me something more interesting than the above three ideas and I’ll listen. I’ve been against HS2 in the past – I’m prepared to change my mind if someone can come up with something realistic that actually tackles problems (instead of something wooly).
