What to do with Voyagers?


Oxford- Virgin Voyager, originally uploaded by Henry░Law.
Voyagers are a high speed diesel electric multiple unit train built by Bombardier and introduced in 2001 for Virgin Cross Country services. There are two varieties of Voyagers, class 220 and class 221, the latter having tilt capability. A further class of similar trains were built for the Midland main line and are called Meridians, designated class 222.

As originally built the class 220 units were four car and the class 221 made up into four and five car sets. The trains were originally intended for a high-intensity service centred around a hub at Birmingham New Street. This was known as Operation Princess but it proved unworkable, led to severe overcrowding on some sections, and was abandoned after a few months. After that, the Voyagers ran in pairs over the busier sections of route - an uneconomic arrangement as two sets of train crew are needed. It is also unlikely that this type of train would have been considered if the operation of eight car trains had been contemplated from the outset.

There have been many criticisms of Voyagers, mostly relating to passenger comfort. The seating capacity is low and the seating is cramped, luggage capacity is inadequate and engine vibration is intrusive. One reason for the low seating capacity is the space taken up by wheelchair access toilets, of which there are more than required by the regulations. They are also heavy; class 220 intermediate cars weigh 44 tons and class 221 52 tons, compared to 35 tons for a hauled mark 3 vehicle.

With the go-ahead having been given for additional electrification, it has been proposed that additional Voyager cars be built with pantographs, so that the trains can switch to electric power on electrified routes. This is in principle a similar concept to the Hitachi IEP train, with similar advantage of flexibility and the similar drawback that costly equipment is being carried around uselessly all the time.

What else could be done with these trains? There are 34 class 220s and 44 of class 221. That gives 156 driving cars and about 200 intermediate vehicles. What if the engines were removed and the cars used as hauled stock, the end vehicles becoming control trailers? They would then augment the fleet of hauled mark 3 stock and the trailer cars presently running within HST sets, all of which are now known to have a live expectancy of at least 60 years from their date of construction.

One of the benefits of this scheme is that the Voyager cars are compliant with accessibility requirements, which mark 3 stock is not, and combining vehicles of the two types would avoid the need for an expensive small build of accessible vehicles compatible with mark 3 stock. Such a scheme could provide Britain's railways with the ability to react flexibly to traffic requirements, something that is painfully lacking at the moment.

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...
