I read somewhere it would be so they can run right through to wherever on the continent.


If it's only going into Euston, and the continental link is St. Pancras... problem?

It's not 'only going into Euston'; it will link directly to HS1

Sorry; the BBC news reported this evening the HS2 line would run from Euston.

Aren't they just a few hundred metres apart.

Maybe as the crow flies, to walk it's about half a mile.

Sorry - my answer was ambiguous.

HS2 won't only stop at Euston; it will also link directly to HS2

I'm confused.

Ah... the wiki appears to have an answer:
Quote:
Connection to other lines
High Speed 1
The government command paper stated:
... the new British high speed rail network should be connected to the wider European high speed rail network via High Speed One and the Channel Tunnel, subject to cost and value for money. This could be achieved through either or both of a dedicated rapid transport system linking Euston and St Pancras and a direct rail link to High Speed One.[45]
The engineering study conducted by Arup for HS2 Ltd costed a "classic speed" GC loading gauge direct rail link at £458m (single track) or £812m (double track). The connection would be from Old Oak Common to the High Speed 1 St Pancras portal, via tunnel and the North London Line. A double-track high-speed connection would cost £3.6bn.[46]
The High Speed 2 report recommended that, if a direct rail link is built, it should be the classic-speed, double-track option.[47]
In December 2010 it was announced that a connection will be made with High Speed 1 as part of the first phase of construction using a tunnel between Old Oak Common and Chalk Farm on the North London Line, and then using existing lines to connect north of St Pancras.[28][29] The proposed connection would be built to GC loading gauge and would not be suitable for high-speed running.[48]

It would be idiotic if they didn’t connect to HS1. That will connect the rest of the country to Europe. Expect EuroStar to build a terminal in Birmingham eventually. Also expect trains from Europe (TGV, Thalys, etc.) to run to major UK cities. I’d expect eventually an HS3 to Belfast running from Birmingham via Liverpool.

I just hope they build really long platforms at all the stations.
That's the problem with the current network: We can't just make the trains longer.

Plenty of countries have double deck trains with rolling stock occupying much the same space as single deck trains. Why we don’t use those is beyond me.

It's been tried, notably in the 1950s on the Southern Region into London.

http://en.wikipedia.org/wiki/SR_Class_4DD

The problems are we have a smaller loading gauge than most of Europe - a legacy of inventing railways, sadly - and it took longer to disgorge passengers from the double-decker stock. I was suprised to learn they lasted into the 1970s, though. :geek:

Now, for a completely new build, there's no reason why a larger loading gauge can't be adopted and double-decker trains introduced. We all know, though, that won't happen.

Why not break from tradition and go with wide body double deckers on a wider guage, now that would be looking to the future. Should also consider running the trains in vaccuum tunnels to increase speed and reduce wind resistance and noise.

That is the future, and of course Britain will not be leading the way.

The Channel Tunnel and HS1 (and the plans for HS2) are cleared to UIC-GC, the same as all of the French LGVs, and I believe there's talk of upgrading the WCML to UIC-GB+ at some point. At present the Eurostar-373s and Javelin-395s seem to manage just fine in single-decker configurations, but I can see how running something like TGV-duplex on HS2 would take a lot of the strain off of WCML, a line which gets very overcrowded at peak/commuter times. Then all we need to do is convince Crosscountry to run doubled-up nose-to-tail Super Voyagers on the NE-SW line, and all the capacity problems are being managed. Reduce ticket prices and everything is awesome. (If only life were that simple).

Tunnels and Bridges, I'd imagine. I'm not quite sure how a double decker train can have the same cross-section as a single decker one, unless you keep the lower deck for people under 5' in height.
