Following the newly-commissioned +6,000 mile rail route to Madrid, from near-ish Shanghai, plus extremely ambitious talk of a new trans-Siberian route across the Bering strait to Alaska, is rail set for a long and secure future? Or do you see this as just more deliveries of Chinese crud?

I expect that HS2 will eventually be built, but don't hold your breath!
I expect that some de-speccing and value engineering will be applied and that it wont be that much faster than existing routes, probably about 140 or 155 MPH.
A new line to the north is needed as much for increased capacity as for increased speed. The existing west coast route is full, and with a growing population, AND a growing proportion of that population choosing rail, more capacity is becoming urgent.
Rail freight is increasing and together with local passenger trains could make better use of the existing line once the faster and longer distance services move to HS2.
The electricity demand is certainly a cause for concern, but probably better than the extra FF burnt by cars and aircraft instead.
Electricity can be obtained from renewables and a fair proportion already is. Aircraft, and cars suitable for long journeys at motorway speeds are almost totally FF reliant.

Double decker trains would require the replacement of huge numbers of bridges, and most of the electrification structures, almost certainly more expensive than a new route.boisdevie wrote:If it's a capacity issue then why not keep the lines we have but have longer trains or double decker trains? Surely even adjusting bridges would be cheaper than a brand new line?
The scale of engineering works required would also mean years of disruption.
Longer trains are a remote possibility, but would require a lot of land purchase and demolition.
Considering just Euston station, the platforms would need to be extended across not just the station forecourt, but also across the Euston road.
Similarly large scale alterations would be needed at other principle stations, with some* alterations at even small stations*
The present long distance trains on the west coast route are up to 11 coaches in length. Trains of twice that length would probably be full in a year or two, so for the long term we need to consider trains of up to 36 coaches, not actually impossible as many freight trains are that long. But think of the walk to the other end ! moving walkways needed at larger stations. The train length would be comparable to the distance between some stations on the underground.
(And I would expect a Pullman restaurant car EACH END of a train that long )
*Smaller stations would not need platforms long enough for the entire length of the train, passengers would have to board and alight from the portion in the platform. However the whole length would have to fit between signals and junctions.

Going back in history, Crewe was tiny and the railway only went there because the good folk of Nantwich didn't want it....biffvernon wrote:So that's the first four miles that isn't going to be built. Why bother with Birmingham then, when one could save money by stopping at Solihull?The impasse suggests that HS2 chiefs may have to end the line at Old Oak Common,
In 100 years or so, Solihull might be a Metropolis and Birmingham a backwater....

In the Australian news there was a passenger train of length more than a kilometre. Admittedly this is a tourist train but such things are possible. There are also double decker trains in Sydney.adam2 wrote: Longer trains are a remote possibility, but would require a lot of land purchase and demolition.

The train comprised 44 carriages and two locomotives with six restaurants on board.
G'Day cobber!
Seems we're cancelling planned rail electrification works:

Shame. These cost a tiny fraction of HS2... and in fact that unplanned bung to Northern Ireland would have gone a long way in paying for it.
