Electric.
Granted you need the infrastructure, but once it's there, you no longer have to rely on a single fuel source and they are generally more efficient because you don't have the added weight of carrying your fuel source around with you.

It will always be steam for me, the most reliable in all weathers :)

Is it the fastest in normal weather? No.

electric for me

What a totally pointless discussion. The relative advantages and disadvantages of all three modes of traction are all clearly understood, and a few seconds research would have led you to the information.

It's not pointless I was just saying!

Agreed. Just a shame we can't seem to make overhead wires more attractive. :roll:

Now, if you asked me which one I preferred as an enthusiast rather than 'which one is best', steam always wins! ;)

As an enthusiast, steam without a doubt. However, as anyone with a modicum of sense, electric with a few diesels as backup in case the power goes off and for shunting. The vast majority of traffic works best with electric traction, where electrics are capable of higher speeds and quicker acceleration for passenger, and moving massive loads for freight. They also don't need to idle, and so don't waste energy when sitting still.

From a personal point of view, diesel.

Taking my crank's hat off it has to be OHL electric, clean, fast, reliable (as long as you make sure the infrastructure is sufficiently robust <D). You only have to look and compare with Switzerland.

Totally agree.

Although I like steam and diesal as an 'enthusiast', I prefer the electrics and 90019 has already described the benefits. It also helps that I love EMUs over anything else anyway! :D

In your opinion which is better and why? :D

Out of these? Petrol and gas-turbine, thank you.

The first for compactness and no-frills adaptability (like in frontline services) and the latter for the sheer wasteful wonderfulness and high-revolution engineering requirements.

(Any more semi-needless, opinion-based queries around? ;))

Same thing, still sounds amazing <D<D

And looks much better than a 'Vectron'...<(<(

The transmission losses for electricity are probably more than the penalties incurred by hauling round a few hundred gallons of diesel :D:D

NEVER as simple as it first appears ....................

Indeed it's not.
But you also have to take into account fuel used whilst a diesel is idling as well, and I would say electrics are likely to be more efficient than a diesel overall.

Petrol and gas-turbine.

Darn, you beat me to the gas turbine quip... But here's a thought:

Union Pacific's gas turbine locos were ideal for sustained high rev running but ceased to be cost effective when their gloopy low grade oil became a source for manufacturing plastics and, as a result, rocketed in price. Oh and the oil used to clog up the filters and blades.

I've just spent two weeks driving an Ethanol 85 (reconstituted sunflower oil..) powered car in the USA. It's cheap and still runs fine. And I wondered if it could be viscous and cheap enough to use in a contemporary gas turbine unit. Scientists and brainiacs out there - what say you?

Yes, the one asking if we should revert to steam, the one about new pacers and the one about ditching the 3rd rail system. To name but a few. This forum used to be a place for some intelligent railway-based discussion, not any more it seems. :(

Diesel - I like the versatility of diesel units and trains, the fact that they can work on any track type, be it third rail, fourth rail ect. Yes the fuel cost, but with Traction such as 165s that can go 1000 miles between refuelling, it really is the way for me.
