Crossrail alternative

I have had comments on my alternative proposal. These are

Where is the link to Shenfield?
Where is the relief of the Central Line from Essex to Oxford St?
Where is the link to Heathrow?
Where is the link to Maidenhead?
Where is the link to The Royal Docks and Abbey Wood?

My alternative proposal does not address these but
(1) Shenfield is not an important destination. Chelmsford might be.
(2) People should be encouraged to use the airport on their side of the capital.
(3) Passengers would continue to have to change at Stratford. This is not ideal but changes are acceptable if the design of the interchange is satisfactory.
(4) Maidenhead is not an important destination. It is not a hub and has a population of 60,000. Reading is a worthwhile destination but would involve major infrastructure works. High Wycombe would be better than Maidenhead as it has almost three times the population, and this would make use of the redundant GW line as far as Ruislip.
(5) The Royal Docks and Abbey Wood are served by the DLR.

The disadvantage of reduced connectivity would surely be offset by the much more reliable service that could be run from Hammersmith to Stanmore. It has only two termini instead of several, and the route involves no junctions or conflicting movements, which is where delays come from - it is a simple shuttle service which would give conveyor-belt reliability and optimum capacity. It would also, incidentally, give much improved services in the densely populated North Kensington area.

Like Thameslink and Cross Country, Crossrail will give rise to something called network delay propagation; there is a body of literature on this subject. I hope people will take notice of it before the scheme goes ahead.

Overshadowing all of these issues, however, is the uncertainty over which will be the major areas of expansion in London and the South East

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...
