Re: Hydrogen Vehicles
Switzerland is a bit like Cornwall, has a lot of railways, if the hill gets too steep the train drags itself up on a rack

Cycling-of course, but it is far better on a Gillott

Re: Hydrogen Vehicles
Yep Swiss federal rail is 100% electric. TBH the terrain of Cornwall is pretty tame in comparison. No excuse whatsoever for sticking with the filthy cancerous diesels on the branch lines let alone on the main routes.

Surely that is the same for liquid fuels? Also if they running heating or aircon that will use juice.
Talking of hills, the Electric train from Soller to Palma in Mallorca goes over a mountain! It's over a hundred years old and made by English Electric in Trafford Park Manchester. There is a big brass plaque in the drivers cab. Originally used to transport oranges to the port.

Having been on the railways in Europe, the terrain is nothing like it is down here. It's bad enough cycling down here without building railways and then electrifying them. All the good easy ones were removed by Beeching.
Take the train from Exeter all the way to Penzance, let alone the branch lines, and you'll see the issues.
So come on what are the special "issues"?
Tell us please.
Have YOU ever been on an Alpine railway?
Any mainline gradients are not a problem.
Indeed leccy trains are easier on the trackbed because of the smooth and incredible torque.
They leave diesels standing on acceleration.
Clearly old lines present some tricky bits and headroom in old tunnels/bridges may be an issue depending on engine height.
Build a slightly lower engine unit so there's room for the pick-up mast is one obvious solution?
No fumes in said tunnels is just another electric advantage.
Your Cornish railways could be running on tide, wave, wind, biomass and solar, or whatever generating source becomes available on and on into the foreseeable future. Future proof.

Only if the engine is switched off, and so many drivers are reluctant to do that. I see, hear and smell lots of vehicles stationary, engine running with or without the driver, for minutes at a time. Why do they do that? I hope those drivers don't whinge about the price of fuel.

It's the same the whole world over
It's the poor what gets the blame
It's the rich what gets the pleasure
Isn't it a blooming shame?

I have been on the Soller railway.
It's great.
Especially enjoyed the being able to stand on the open "porches" at the carriage ends.
It does go through the mountain too, I remember a tunnel.
Actually most diesel (or other liquid fuel)buses and trains do continue to run their engines at stops and stations. And in the case of buses in traffic jams too.
Electric power in the case of trains is still used for air conditioning, lighting etc of course, but in that sense it is not simply wasted as in a stationary diesel and it's clean of course. Most trains have back up batteries to cover those systems in event of overhead power failure.
I remember traveling to Inverness on the sleeper, Intercity125 I think, beast of a thing.
Idling away in Inverness station it produced a stench and a fug that was truly and memorably foul.
Such a contrast to a leccy one, freshly rolled into gay Paris, fly bespattered and hot but stench and noise free.

Re: Hydrogen Vehicles
The cleanliness of all elecric vehicles depends upon their energy source (though of course point pollution is easier to treat than diffuse pollution). But France has an entirely electrified railway and very low carbon emissions in terms of energy production through 58 nuclear power stations.
So you takes your choice - for better or worse it's what France does. It's difficult to know how sensible or not it is; I did see reports that the recent heatwave would cause some reactors to be shut down due to low river levels, which does make you wonder about their efficacy in the future.

Interestingly, unless the electricity is coal generated, e- vehicles are so much more efficient than ICE that carbon emissions are lower regardless of source. The UK burns almost zero coal.

A rather ironic argument given that the intensity of the heat wave has been exacerbated by fossil fuel emissions...

Wasn't intended to be an argument - simply a reflection - and their long-term use. Though to be fair France is trying to reduce its dependence on nuclear.

Re: Hydrogen Vehicles
I see the EU now wants EV's to have some form of sound warning when travelling at low speed. Now that is a good idea, how about Mr Whippy chimes?
Re: Hydrogen Vehicles
Chatting about this on the Prius forum.

Silly idea IMHO.
Pedestrians don't look, as I've noticed for years when cycling. We had a Clio 1.6 16v for many years bought new in 2001, and that was silent at walking pace at tickover. Many was the time we surprised walkers on the lanes. Now have a Yaris Hybrid, and I reckon under EV drive, it's the same as the Clio.
The new rules only regulate for going forwards. No noise regs for reversing!
All that's required, is for pedestrians to look and pay attention when crossing the road, or walking along a pavement-less lane. Also, bicycles have bells and cars have a horn. Nothing wrong with a friendly ding or toot.
Could it be that the rise of the diesel cars have made pedestrians think that all cars rattle at tickover?

Apart from the bit that says "when reversing".

Electric trains could run on battery power through tunnels with the mast retracted and recharge out the other side when reconnected to the "mains" .
As I posted earlier in the thread it's not beyond the ken of man to solve the problems.Profit though gets in the way of service.
