Roughly what proportion of the total energy usage of high speed rail is represented by the trains themselves running? I've seen the Tender documents and the numbers for usage/km seem quite modest but I've got no sense of how much it takes to run a HS system
If you look at the recent TGV duplex then maximum power for each train is quoted (wiki) 9000Kw for 600 passengers, so 15kW per passenger.

The trains won't use full power, they do use regenerative braking, and on the flip side there will be a lot of transmission losses.
There's a longer analysis here:

Looks like 4-500 mpg for well filled high speed trains.
2-300 mpg for well filled buses.

1: The cost of energy is a small portion of your ticket cost.
2: The trains are the major user of energy on the rail network, only a few % is lost in the power supply and all the other energy uses are much smaller.

Latest Office of Rail and Road finally published the latest passenger numbers with a circa 19% increase in passenger numbers and a growth of revenue. The Elizabeth Line does add significant numbers but definitely an upward trend in rail usage.

What a shame the govt have cancelled the only major rail infrastructure project and salted the earth to prevent it being restarted without years of delay and much unnecessary expense.https://dataportal.orr.gov.uk/media/ip3ayian/passe...

Even so, the right decision given the enormous costs involved - however caused/whether justified.
It isn't; if he wanted to save money there were ample areas to cut out or value engineer, as it is he's pissed hundreds of millions up the wall for nothing and rendered the expenditure of billions very poor value while spinning bullst about investing elsewhere in the network. This was it, there are no rail projects ready to go and no other means of increasing capacity, just this honking great behemoth which looked expensive because it had been lumbered with a load of unrelated costs and managed poorly. Now the best that can happen is Labour getting in and reviving rail investment but without the lies and bullst.hidetheelephants said:

It certainly should have been cancelled much earlier !
Thank you, Ned Ludd. Traffic is up on a network already bursting, it needs more capacity and HS2 was the only game in town, or it was until Rishi Beeching took his axe to it.A wasted opportunity for much needed improvements to an essential service.
Some of us can see this. Others not so much.

It may well be needed, I'm not going to claim any knowledge to the contrary.
However.......
It seems to have been cancelled finally due to costs being way over estimates.......How come ? - poor estimates, excessive spending, time/delays, pandering to too many others/NIMBYs etc ??? Possibly all of those.
Rail *income* from passengers is still much lower than expected (I realise that pax *volumes* are now high at weekends etc)
A proportion of travellers appear to have switched to cars, or just not travelling at all (Covid?)
Passenger trains were to terminate way out of central London (Old Oak Common ?) for many years.
Some freight operators had suggested that they would consider moving some/all of train loads to road haulage if costs got too high, or strikes interfered with their requirements.
If it had been planned to start from the Manchester end would the whole project have even been approved ?
Given the poor outlook I don't think many of the UK voters were too bothered by the cancellation of HS2.

ALSTOM looking to cut manufacturing capacity in the UK due to the curtailment of HS2, that’ll be another nail in the “Green Jobs bonanza “ bubble that we were looking forward to reaping the rewards of.

To be honest the fact that there are 500 odd perm jobs and nearly 800 contract means they have clearly been worried about the place for a while! You only do that to make it damn easy to dump millions in payroll at the drop of a hat when you have to
That's how most manufacturing works these days, nothing unusual about it. If the govt hadn't had their IR35 brainfart it would probably be a higher ratio of contractors.Yertis said:

I think the issue is not the curtailment of HS2 but the fact that they don’t have any orders between now and the start of the HS2 rolling stock production, so here’s about an 18 month gap without much work.ALSTOM looking to cut manufacturing capacity in the UK due to the curtailment of HS2, that’ll be another nail in the “Green Jobs bonanza “ bubble that we were looking forward to reaping the rewards of.
