Batteries to act as a backup for short distances seems feasible, and they can be charged from the overhead power lines as well as using regenerative braking on downhill sections. Here's an interesting article:
http://www.esg-rail.com/are-battery-...ification.aspx
I suspect locomotives as such have probably had their day and the future lies with multiple-units in which each carriage has its own motor and power supply.
I have never been a fan of Voyagers. They are horrible. noisy things. The HST is a much quieter and more comfortable train, and is still very reliable. I loved the sound of the original Paxman Valenta V12 diesels, but since being re-engined with V16 MTU diesels they run much more cleanly, and with more power.

However, am not convinced that (taken overall) a modern diesel train will result in greater emissions than an electric train. In fact I would have thought the reverse was true when all of the losses are taken into consideration.

Not only that, production of the steel and copper used to provide the overhead lines, and the vehicles needed to install them will also create significant emissions 'somewhere else;.

So no more sheds on our railways?

Likewise, long distance power transmission lines and undersea links are inherently lossy; which is why many use DC power to minimise capacitive losses at least. Resistive losses are unavoidable.

We have a few large-scale power storage plants here in the UK, which are effectively hydro-electric generators put into reverse when there is a surplus of power in the grid. I don't know how efficient these are, but they can provide large amounts of power at very short notice.

So whilst storage batteries may save the power companies from having to invest in generation capacity for peak periods they don't actually save energy unless used by consumers to directly store their own wind or solar power for their own needs.

This is my argument against electric cars. The Greenies see them as a pollution free utopia, whilst conveniently forgetting where the power comes from! In truth, they simply create even more pollution 'somewhere else'.

Look at it another way: is it more efficient to burn gas to boil water to create steam to drive generators to transmit power along hundreds of miles of overhead cables through dozens of step-up and step-down transformers to charge a battery to turn electric motors to drive a car, or simply to put petrol in the car to drive an efficient engine through a gearbox?

Electric cars would be fine if all of our power was renewable, but not when we still rely heavily on burning coal and gas.
The way the world is heading under war clouds gathering, it may all be over for humanity within a decade or less. I see a convergence of adverse global Geological, Meteorological, Political and Financial events that are escalating by the year.

Things certainly don't look good right now do they? Too many lunatics in charge of the asylum, and too many of the PC brigade letting them get on with it.

If I hear the Trumpet sound I shall take my toothbrush and go.

Just so long as there's lots of naughty girls, I'm in.

Afterthought: I guess they wouldn't be there if they weren't

re What happened to Kodak, well.. they sold the division that I was working for and that stopped my access to Kodachome / Ektachrome at staff prices so I switched back to Velvia

I went there (Rochester NY State) a few times in the late 90's and then again in about 2014 and the difference was amazing - badk in the early days the Kodak site was so large it even had it's own power station inside the park, but that's been sold as has a large part of the land

I do remember some good times like the time I said to someone in marketing I was running a photo competition and a few boxes of film were sent to me .. not a few rolls.. a few boxes of 36 rolls

back to your point.. yes we live in disruptive times.

Surely, as it's Hell we are talking about, the place will be full of gorgeous, sexy and very willing girls who absolutely adore us - and we will all be totally and permanently impotent!

Except for the impotence bit (of which I'm in denial) your vision sounds more like heaven.

The Voyager is like a Rolls-Royce compared to a Pacer! But I agree about the HST, I still prefer to travel on one of those than the electric trains on the ECML. There is a fine video on YouTube of an original HST with Paxman engines leaving Newcastle station with an enthusiastic driver! The "sheds" carry on but there will be no new ones now. If @Pandora is right it's not going to matter very much anyway ..

Sorry I missed your post earlier, Andy.
As a pro wedding 'toger I used Fuji 400H, never tried Kodak.
That was generous of Kodak to gift you several boxes of film.

Well, at least there will be no shortage of MP's down there to lobby about NHS services.

Having said that, I'm sure Blair and Mandy will talk their way past St Peter.

Re: The Exponential Age?

It's Donald whose destination will be worth watching out for - with that cherubic face I'd wager he'll be blowing his own trumpet in paradise surrounded by adoring angels. God may even offer him a sainthood. As for Bashar, he's buggered, Old Nick will make use of his talents as Commander of Chaos. Then of course there's Ķim, Vladi and Li, but at 2:30am I'm leaving it to you to foretell their destiny .... back to bed for this ole sinner.
