I don't think the situation is as bleak as sometime suggested...
I understand what you mean Paul, and in many respects the railways are doing well in what is turning out to be a tough time for individuals and businesses. However, without ignoring economics, a vision of what the railways could be if piecemeal party politically schemes did not hamstring their development would give a sense of direction and a goal. That would end the feeling that any growth is incidental to a strategy rather than at the core of it. The
RUS▸ always makes good reading (no irony intended), but look at Crossrail and
HS1▸ to see how political expediency delays and prevaricates over what most people agree are sensible projects for the country.
No truer words ever spoken! 40% of railway in
UK▸ is already electric, yet 60% of journeys are on electric trains. That number includes the less-than-ideal third and fourth rail systems, and it is difficult to see any new project other than a tramway being electrified at anything other than 25kv AC.
EMUs▸ and electric locos typically are expected to last 30 years, with a midlife refurb. So on the day a new train goes into service, we have a good idea of the day it will retire. There is typically a 10-year lead in for new schemes - the
GWR▸ electrification was announced in the early 1980s, only to be cancelled and re-announced and cancelled again before being actually started. There was no reason for this other than political inertia. My idea would at least mean that any government tampering with the masterplan would have to say why.
The argument about whether or not to electrify the railway has already been won. As a one-time flier of light aircraft, I understand more than most how the fuel efficiency of a vehicle is affected by the fuel it needs to complete the journey.
Steam was brilliant in opening up mass transit. It still is, but is unsustainable economically. Diesel was the saviour of the railway, being more flexible and more efficient than coal, but electric is surely the future. The
HSTs▸ use two diesel engines to generate electricity to drive the train. That is efficient compared to cars, but hugely inefficient compared to a real electric railway. Not only do you not have to carry the fuel for the journey with you, so lessening the load, but you can generate the power source away from the cities by the best available method. HOOP is the answer to the conundrum, but the conundrum is not the question.
I bought a new car under the auspices of the then trade in scheme for old bangers. My car was just 10 years old, and did 40 mpg on a certain journey to north Wales, something I thought was brilliant compared to my previous vehicle. The new one did 60 mpg for the same journey, and had it been powered by electricity all the way would have been even better.
Diesel has no long-term future in any kind of transport, let alone public transport. A diesel-powered electricity generator at Avonmouth makes much more sense than importing diesel to power a train, if only because it is more efficient than a wind farm, more likely than a biomass plan where we import some wood from the USA and pretend that the ship emitted nothing on the voyage.
