Pay attention to Captain Deltic


Prototype Deltic., originally uploaded by steven.barker57.
Captain Deltic, otherwise known as Roger Ford or Uncle Roger, has a long running series in Modern Railways, under the heading "Informed Sources."

And informed they are. He does his homework uniquely well, bringing together the physics, the engineering and the economics of railways. Anyone involved in making decisions about railways should study his writings assiduously.

Unobtainium
Correspondence I have received through my MP shows that the DfT civil servants are not paying attention as they should. That is one reason why £20 million came to be wasted on consultancy work in connection with the aborted Inter City 125 replacement, which, as Captain Deltic pointed out, was going to have to be constructed of a new metal he called "Unobtainium".

His latest piece is an analysis of the refurbishment opportunities presented by the fleet of trains inherited from British Rail. It is just as well, as he points out, that vehicles such as the mark 3 have an economic life of at least sixty years. This is the thinking that is going to be needed to keep the wheels turning over the next decades.

My only criticism of him is that he has a bit of a blind spot about kettles. This technology has had a boost in recent years. As potentially green off-the-wires traction, able to run on any fuel, and with a low construction cost, he may be missing something that needs to be kept an eye on.

There's one example of a train vaguely similar to the "Intercity express programme" trains - the RENFE 130H (currently not in service)

The trains are basically a RENFE 130 (Talgo 250) trainset with generator vans added containing MTU 12 cylinder engines - very similar to the ones used to remotorise some Intercity 125s) - these are for non-electrified parts of the Spanish rail network - once the lines are electrified the trains can be converted back to all electrical operation.

See http://www.cope.es/tecnologia/14-12-09--nuevo-invento-espanol-tren-todoterreno-115520-1 for details (in spanish)

At a simple level this is what the dft was asking for. (ignoring variable axles, loading gauge etc) However having read their specification I know that a 1435mm version built to UK loading gauge would not have been acceptable to them - their specifications were far to specific (some commentators have used the term 'micromanagement'). I don't know if the RENFE trains come even close the the demands for increase in energy efficiency set out in the dft documents.

Nevertheless it does show that the concept of a diesel and/or electric high speed train was not a complete fantasy.

Still I breathed a sigh of relief when I read that the whole thing had been halted subject to a new report. As I understand it 'on hold pending independant report' is Whitehall speak for "quietly killed off". I hope so anyway.

Importing people to sustain demand

I got involved in a discussion with a Youtuber called “Philosophy all along”. This was in connection with criticism of Trump’s policy of deporting illegal migrants, which he argued would be bad for the economy as it would reduce demand. This implies that there is a need to import people to sustain demand. There is no obvious reason why a population should not be able to consume everything that the same population produces. If it can not, then something else is going on. It is a basic principle that wages are the least that workers will accept to do a job. Wages are a share of the value added by workers through their wages. The remainder is distributed as economic rent, after government has taken its cut in taxes. Monopoly profit is a temporary surplus that after a delay gets absorbed into economic rent. Land values in Silicon Valley are an example of this; it's like a gold rush. The miners get little out of it. Rent and tax syphon purchasing power away from those who produce the g...

The dreadfulness of British governance

I wrote to my MP on two entirely separate issues recently. The first was to do with the replacement for the Inter City 125 train, which at £2.6 million per vehicle, is twice as expensive as it ought to be. The second concerned the benefits of a switch from business rate and Council Tax to a tax based on site values. In both cases, the replies were full of spurious, unsubstantiated assertions and completely flawed arguments. This is typical. You will not get an iota of sense from the government on any area of public policy at all - finance, economics, trade and employment, agriculture, housing, health, transport, energy. All junk. If you write to your MP you will invariably receive answers that are an insult to your intelligence, no matter what subject you are writing about. Of course they cannot understand statistics. They are innumerate. Whitehall is staffed with idiots with a high IQ. Look at their IT projects. And mind your purse, they will have that too.

How much more will the British tolerate?

The British are phlegmatic, tolerant and slow to rouse. Thus there was no great reaction after the terrorist attack in July 2005. The murder of Lee Rigby created a sense of outrage, but nothing more, since it appeared to be an isolated incident. Two serious incidents within a fortnight are another matter. Since the first major terrorist incident in 2001, authority has tried to persuade the public that Islam is a religion of peace, that these were isolated events, or the actions of deranged "lone wolves", having nothing to do with Islam, or to reassure that the chances of being killed in a terrorist attack were infinitesimally small. These assurances are are beginning to wear thin. They no longer convince. If government does not act effectively, people will take the law into their own hands. What, however, would effective action look like? What sort of effective action would not amount to rough justice for a lot of innocent people? Given the difficulties of keeping large n...
