Two into five won't go



Railways approach Göteborg from five different directions. Starting from the twelve o'clock position, these are Strömstad-Uddevalla, Trollhattan-Älvängen, Stockholm-Alingsås, Borås and Copenhagen-Kungsbacka. There is no route across the city which has a significantly greater traffic potential than any other, and the connect must necessarily be arbitrary. Whichever lines are joined by a cross-city link, most journeys through the city centre will inevitably require a change just as they do now. If services from the two lines from the north continue onto the one line from the south, the result will be that the southern line will be unnecessarily congested and the potential traffic will be insufficient for the service provided. Or half the trains will have to turn round and go back.

A further drawback is that passengers travelling to and from the south to the city centre and northwards will actually experience longer journey times due to the detour they will now be making through having to make a trip all the way round the city centre through the expensively constructed tunnels.

In these circumstances, there is only thing to be gained from constructing a cross city link, is the reduction in the number of trains terminating at the central station, and the associated costs of platform occupation and train movements.

Against that is the disadvantage of joining separate networks: that delays and disruption are propagated from one network to another. A failure at, say, Alingsås will lead to cancellations at Kungsbacka an hour or so later. This was precisely the experience with London Thameslink, a long-distance cross-city route.

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...

Battery trains fool’s gold

A piece by the railway news video Green Signals recently reported the fast charging trials for battery operated electric trains on the West Ealing to Greenford branch, in west London. In a comment under the video, I described the project as technological overkill, bearing in mind that before dieselisation in the 1960s it was worked by the tiny steam locomotives of the Great Western 1400 class, a 1932 design based on an 1870s design. The money that has been spent on the experiment would have paid for a small fleet of the old things. Elsewhere in the comments, I was critical of the 800 series trains. This produced a response from the makers of the video, as follows. “I may be grasping at straws here but I am guessing you don't like 8xx series trains all that much and rather wish we still had Kings, Castles and (for the branches) 14xx's. Fair? ” My reply was as follows... Yes you are grasping at straws. The model for long distance stock is the class 180, which is a 23 metre veh...
