A new approach to UK politics

The intention of this blog is to logically create a new framework for British politics keeping to the following guidelines where possible:

• No critcism without an explicit or implied positive contribution

• Only use plain and clear language

• Make sure all arguments are reasoned and reasonable

Off The Rails or Why Trains are the Black Sheep of Transport Policy

Trains are quick. Rail transport is efficient. It can be an extremely pleasant form of travel (as long as you can get a seat and relax, of course.) So why is it the that trains are not the main means of long distance transport in this country?

I accept that passenger numbers are increasing (as anyone with an interest is always quick to point out) but this is a long way from saying that the railways are doing well. Passenger numbers might be on the rise but comparable figures for road and air transport must be going through the roof. I haven't looked at the figures (if any exist,) but who can seriously tell me that rail is keeping up with the fantastic inflation of transport in general? Roads are always being built and completely renovated and airports are constantly building extensions. Why is it then that the rail network is, in the main, limping along with little visible improvement? It seems that the prevailing attitude is to create brand new roads whereas the rail network is merely being 'maintained' and 'upgraded.'

If the economic playing field was level, train travel and rail freight should be way ahead of the competition. If anyone can see a good reason why this shouldn't be the case please tell me because it eludes me. However, for some reason rail transport is disproportionately unreliable and expensive compared to the other transport options (in this point I agree with Transport Watch, but I disagree with their assumption that it is naturally so). Some reasons for this discrepancy are:

  • As Tim Worstall suggests, operators are raising prices to discourage passengers since system is at capacity. This is more or less their only option as system capacity is largely out of their hands (since Network Rail is responsible for the underlying infrastructure)
  • Train leasing companies (e.g. HSBC) recoup the cost of the trains in 3 years. In a way they have to because the operator only has a short contract, but this does mean that the banks have the operators by the short and curlys and there is nothing the government or passengers can do about it.
  • I say this with a bit of reluctance, but I think it is possible that safety standards have been set too high (as compared to roads, say,) and that the cost of the associated bureaucracy and insurance is crippling.
  • Poor management. I don't know enough to say where, but surely not everyone's hands are tied by the above points? Everyone seems to be making a meal out of maintenance and new track - but to be fair this may well be to do with the way the system was split (and the inevitable layers of contracts that are required at each new interface) rather than the managers who now have to make it work.

I think that the problem here is that there are so few rail infrastructure contractors and financial institutions that support the industry that although the network has the facade of privatised competition, these few players make monopolistic layers that run right across the service. These no doubt cream off huge profits (see leasing above) while operators probably do have to scrimp and save and put up prices to make any kind of money at all.

This profiteering could theoretically be legislated against (aaargh!) but this would probably create (or add to?) the monopoly of a few specialist consultancy firms to get everyone through the red tape!

So now what?

As far as I can see there are three 'possible' options (please put aside your prejudices for a few moments...):

  1. Re-nationalise everything! This may not be as silly as it seems, because you have to admit that the government can afford a few trains and probably wouldn't lease them off itself at extortionate interest. Numerous lawyers fees could be avoided since they could (but wouldn't) employ maintenance staff direct, eliminating complicated contracts and sub-sub-contacts and, more importantly, allowing people to use common sense (of the 'that nut looks a bit loose, perhaps I'll just give it a tweak' rather than 'it don't say nuts in my contract - they'll have to pay extra' variety). Hopeful? Perhaps, but completely impossible in the current structure.

    Obviously this wouldn't work unless the government get a helluva lot better at running things like private businesses have to. This looks rather unlikely, but I'm hoping to have some thoughts on this matter in future blogs.

  2. Build, build, build. Keep the track public (like the roads) but build much more so passengers get real choice (see under duplication in 'The flaws of choice - or why some things can't be privatised'). This would allow more operators and much longer contracts allowing real competion while allowing time for investment to be worthwhile.
  3. Sell everything to the operators and also open up the competitive market by allowing and assisting in building of new private railways (planning and compulsory purchase orders etc.) This was the model for the rail heydays, why not in this privatised age?

There must be something wrong with me because actually I like the first idea best - it's simpler and more compact than the others.

Let's roll!

In anycase, the railways need optimism and someone competent to run them. Current changes and suggestions seem piecemeal and badly planned. After all, they're talking about road charging which will need some kind of fantastic technology to track every vehicle on an open network, yet rather fewer trains don't seem traceable even in a fixed and timetabled system. There is no reason why rail should be so difficult to run or cost so much. Someone out there just needs to make sure that they get it together...

Where does Hydrogen come in our future?

Hydrogen is being pushed as the 'clean' power source of the future, particularly for road transport. Though this future is possible in some respects, the idea as normally presented is highly misleading.

Seen in isolation, hydrogen has some clear advantages over current transport fuels. It's main advantage is that it burns (or reacts in the case of fuel cells) very cleanly leaving only water as a byproduct. This means that it produces no carbon dioxide, greenhouse gases or any other dirt or pollutants. Apparently it also allows higher energy efficiency.

However, one fallacy that never seems to be corrected in public is this: hydrogen is not a primary energy source. Unlike coal, gas, oil, wind, tides etc. it does not occur naturally in any great quantity (on earth at any rate). This means that for commercial use it must be processed from other sources, normally hydrocarbons (oil and gas) or water.

If hydrogen is made from fossil fuels (oil or gas) then, quite apart from them being a limited resource anyway, we are left with all the carbon that was removed in the conversion process. This carbon represents a large amount of energy, but if used (i.e. burned) we would end up with a large quantity of carbon dioxide on our hands. Since every process has its inefficiencies, this looks as though it could actually be worse than just using the original hydrocarbon.

If hydrogen is made from water (by electrolysis, by the way), we do not have the carbon problem. However, you may have noticed that you make it out of water, burn it, and you get water back. This cycle, predictably, is not 100% efficient. We have to put more energy in to make the hydrogen than we get out when we use it. Not only that, but where do we get the electricity for making the hydrogen? From power stations that are currently mainly fossil fueled.

Better than a battery?

The point of all this is that hydrogen must be considered as a storage medium, rather than an energy source. As such, it really could have some reasonable benefits. Vehicles could then be powered (if indirectly) from any energy source - even nuclear or wind.* Thus power produced cleanly and efficiently on a large scale could be used to power individual vehicles. But possibly even more importantly, couldn't hydrogen be used to power aeroplanes? Ah, no I'm not the first to think of it - a short search brings up this.

Another thing to consider is that if vehicles are, in the future, being powered by hydrogen made using electricity, all the energy previously supplied as petrol and diesel will have to come though the National Grid. This will be a significant increase in electricity demand at a time when (with current trends) the supply will dwindling.

So, politically speaking, three things come from the above:

  1. Hydrogen is energy storage and as such cannot be considered a power source.
  2. To have any chance of creating a 'Hydrogen Economy' we need to build more power stations ASAP.
  3. We need to invest in hydrogen powered aircraft?!

Just a little piece of interest to end with: if nuclear fusion becomes commercial at any stage, the power obtained from hydrogen would be more than it takes to make. Many times more in fact - making power literally as abundant as water...

*This could be said of batteries as well, but it looks likely that hydrogen will have greater range and faster refuelling for the foreseeable future.
