Is deisel dying?

[steam for ever]

Yes of course.
You can see which traction I favour anyway.
I have to say that electric is more comfortable than deisel.
You probably are right.
I am most likely thinking of a past version.
I am not really up to date on this.
For this country and now, yes you are probably right.
But I am sure you will agree that 25 thousand volts is rather alot?
Third rail runs on only 700, so surley all the extra is not needed?

I suggest you read up on electricity !

The voltage is stepped up with a transformer because the higher voltages are easier to transmit long distances. You can then have a transformer at the recieving end to step it down again.

You are in danger of making yourself look very silly by discussing things like this with an obvious lack of understanding on the subject.

Still paying for all that infastructure that is needed can cost millions.
Anyway I do know that a huge amount of power comes from coal fired power stations.
I will now come to safety.
I do not see a way how you can say that it is any safer.
Remember the cumbria crash?
The wires were draged down and prevented escape untill the power was turned off.
In an accident this causes havoc.

I come back to the fact that it is expensive.
I metioned this to begn with and Pre65 has actually strengthened my point.
25000 volts over a long distance is going to eat up the cash.
My knowledge may be flawed but so may be the system.
Remember that deisel and electric traction was considered only for shunting work.
Wonder why?

I'm sorry, but if you keep this drivel up I will get annoyed.

PLEASE do not post anything more about the electric infrastructure untill you have an understanding of it.

The whole point of transforming the electric up to 25KV is that it IS cheaper to transmit.

So how does going back to steam locomotives help the environmental argument ?

[steam for ever]

It5 is NOT and I repeat NOT cheaper over long distances.
Wonder why in other countries diesel is used on long distance still.
You have to pay the power company for a start and the wires require attention quite often.
I do not want to annoy you, but lines have been de electrified.
Hold on I have a book here.
Chapter 7 ....lets see....
Ah!
The book I have here is a GCSE electronics book for parents and the modern curriculum stated this sort of thing.

The thing is people 400 years ago did'nt think but knew that the earth was flat.

In the long term it doesn't work.
Are you an electric enthusiast by any chance?

Times do change.
Compared to everyting else overhead power over a long distance is still a fairly new concept.
Don't get too confident.
I have to say I doubt you have actuall seen the bills.

Let me try and explain.

If you wish to transmit electricity over long distances, then by raising the transmission voltage you reduce the end cost. That is why the National Grid use such high voltages as the wires can be thinner and thus the supporting structures can be less massive.

I love steam, I can remember roaming round engine sheds with my ABC and shed guide in the sixties,and I really enjoy the heritage steam movement. BUT there is no future for steam on the "real" railway (apart from specials). I'm sure there will be more new builds in the future, but not "many" in real terms.

I admire your enthusiasm for all things steam but in the "real world" it's never going to happen.

This is a small piece about 25KV electric for railways

Hello SFE,
Because of your unusual and often controversial opinions I think that some of the forum members (myself included) are having difficulty answering your posts. As you are one of the forums most prolific contributors it might help us to deal with you more effectively if you could provide us with some personal information. Obviously I'm not asking you for really personal stuff but your occupation and age would be very helpful. This would enable us to fit your personal experiences into a particular timeframe and would determine the degree of technical detail used in our answers. Hope you don't mind.

I share Steam for evers "gut feeling" that the "electric railway" is taking a sledgehammer to crack a nut.

Whats wrong in a such a densely populated country with the internal combustion engine working at speeds of upto 125mph ?

Does the nation need 200mph electric railways and will they bring significant benefits for the capital outlay ?

Would a High speed diesel with tilting technology and cleaner fuel (perhaps bio-diesel) provide cleaner faster trains at a fraction of the cost ?
