The trouble with cars

The trouble with cars is, They take up too much space and are therefore literally toxic to civilised urban life. One is moving the best part of 1000kg of which less than 20% consists of actual payload. Rubber-on-tarmac is inefficient compared to steel-on-steel. Car-based transport requires the individual to invest in and operate a very expensive and fast-depreciating item of complex and sophisticated capital equipment. Cars are a huge waste of time as it is impossible to spend time travelling in them in a productive way. Off course we all use cars because when patterns of travel are very diverse, there is no other option. But we should not be using cars for journeys in densely built-up areas, and we should also be thinking whether land-use planning is forcing people into the unnecessary use of cars. No technological breakthrough is going to resolve all of the drawbacks of cars as we know them today. We need a better mix of modes, including walking, cycling, buses, trams, heavy rail as ...

New surface line stock for London underground

London's entire fleet of surface line stock is being renewed with a single fleet, to be designated as 'S' stock. Some of the stock being replaced, the Metropolitan Line A60 and A62 stock dates from 1960; most of it, the Circle Line C stock, from around 1970; and the District Line D stock, from 1978/80. All has been refurbished in the past ten years and looks perfectly presentable. Of course there are advantages in having new trains and a single uniform fleet, or ought to be. They can use less electricity through regenerative braking, and they should also cause less wear and tear on the track and need less maintenance. But will they? And how long will it take to realise the savings and recover the cost of the investment? It's just a question.

Professor says "invest in roads not rail"

" Cutting the roads budget marginalises the masses and ignores the fact taxpayers already subsidise niche rail and bus sectors. " So says Stephen Glaister, professor of Transport and Infrastructure at Imperial College, London, in an article in today's Guardian. Glaister is also a spokesmen for the Royal Automobile Foundation and so not a neutral party to the debate. Not very professorial Glaister begins by stating that "For most people, most of the time, the car is public transport. Ninety-two per cent of passenger travel takes place on the roads." That is not a very professorial statement. Is that 92% of trips, or mileage, or what? Anyhow it is not sustainable, not because of carbon dioxide emissions but because of resource depletion, sheer lack of space and the fact that such widespread use of cars is not possible in a small urbanised country with a concentrated population. Nor does further investment to encourage the use of cars deal with the problem of thei...

UK budget row

The budget has caused a deal of uproar with comments like this " The tories will attack anyone and everyone that they don't perceive to be one of their own - White, Etonian/public school, Oxford/Cambridge, old school tie, land owning, bank running millionaires. Not much chance of most people getting into that demographic, although they will favour their lap dogs as the budget has shown. " It is typical of the criticism coming from the Left. It is off the point. Forget their colour, forget their education. There is only one thing that counts. Land owning on the largest scale. Britain is run for the benefit of the handful of people who own most of it, such as the half-dozen "aristocratic" families who own the most valuable areas of Central London, their ancestors having got hold of it mostly by near-fraud about 400 years ago. Though do not forget the Oxbridge colleges, some of whom are also big-time landowners and would not allow anything to be taught that brought...

Full marks for Ubuntu 10.04

There is plenty of good quality computing to be had without spending more than a couple of hundred pounds. For the past ten years or so I used SuSE Linux but since version 11.1 it has been troublesome, so I tried out Ubuntu 10.04 on my laptop, an IBM X31 Thinkpad, probably about six years old. They can be picked up for £100 or so now, having been superseded by the X60 and X61 series. So far, so good. Problems with the sound and problems with wireless connections seem to have been solved and it is fast and generally well integrated. In its overall "feel", it is very much like an Apple, with some slick-looking windows decorations. System management works in a different way from SuSE and a decent broadband connection is needed to set it up in the first place, but I really don't have any complaints.

East of England agency calls for faster trains

Presumably as a parting shot before being shut down, the East of England Development Agency put out a wish-list for improvements to the Great Eastern main line to Ipswich and Norwich, including new trains. The worrying thing about this was the number of things that were stirred into the pot. Necessary infrastructure improvements are one thing. New trains are another, especially since it is now accepted that the mark 3 fleet presently in use has an economic service life of at least sixty years and new trains offer the passenger little if anything more. This is a good example of the wasteful and profligate attitudes that characterised the Labour administration and the bureaucrats and consultants who were living off the system. We are now all about to pay the price.

Locomotive stored out of use

I noticed in Rail magazine that 14 class 66 locomotives are stored out of use. This is not many out of a class of several hundred but it illustrates a more general point. Rolling stock has such a long life, several decades, and in that period changes in economic circumstances mean that it may spend extended periods under-used or out of use altogether. There is a good case for procuring units of lower initial cost even if the running costs may be higher. This is also why it may be desirable to retain old stock in storage rather than rushing to send it for scrap. On the passenger side, it is a good argument for using locomotive-hauled vehicles rather than multiple-unit trains, which gives the operator the flexibility of using a variety of different power units depending on what is available. This is why locomotive-hauled passenger trains persist despite all attempts to get rid of them. However, it is of course desirable to run in push-pull mode where possible to avoid the need for locomo...

What happened to the 1300 new carriages?

For several years the Labour government promised that 1300 new carriages were going to be delivered. They probably will never be because of the cuts. So the trains are getting more and more overcrowded and uncomfortable, which makes passengers opt to go by car or bus instead. Uncosted safety costs lives Now 1300 vehicles is, by coincidence, roughly the number of mark 1 vehicles that were scrapped in 2005, despite the fact that they were good for another 15 years in service. These spacious and comfortable trains (above) were hurriedly withdrawn due to their supposed lack of crashworthiness. Following the serious accident at Clapham Junction in 1989, it was realised that they were well below current safety standards. From that time on, there was an ill-considered and uninformed campaign to get them replaced. But they were still at least an order of magnitude safer than the alternative of travelling by bus or car. And they could have been confined to routes such as branch lines where spee...

Complaints piled on complaints

A few months ago I complained about a whole string of problems I had in the course of a weekend's journeys. Eventually I received £20 in vouchers(4 x £5). Yesterday, my last day in Britain, I used them to pay for my trip from Brighton to Harwich. It took nearly ten minutes to buy my ticket as the man in the booking office had to fill in the details of the journey on each of the four vouchers. I nearly missed my train, which for some reason was parked at the far end of a platform. It was not funny to be asked by a man with a whistle to hurry up, whilst dragging a heavy case behind me. Surely there is a better way of dealing with compensation for complaints? What a waste of time. The train companies all have big call centres to deal with all the complaints, which of course is just the tip of an iceberg of dissatisfaction. What does it cost to deal with them? How much would they save by getting the service right in the first place?

Bidragsberoendet

Den Brittiska regeringen, samt Sveriges, har svårt med bidragsberoendet. Regeringen anser att bidragsberoende är parasiter och vill att alla ska jobba. Men vad är bidragsberoendet egentligen? De bidragsberoende är människor som inte vill eller kan jobba och är beroende av bidrag. Några bidragsberoende är helt och hållet fuskare, förstås. De får bidrag av regeringen men jobbar samtidigt. Några bidragsberoende är bara lata och vill hellre sitta hemma, liggea i sängen och titta på tv-n eller spela på datorn. Några är verkligen sjuka. Och där finns det stora problemet. Det kan illustreras av ett exempel, vilket var typiskt för tjugo år sedan. För många år sedan, och i många områden av Storbritannien var ekonomin beroende av kolgruvor. Arbetet i gruvorna var hårt och smutsigt. Att vara gruvarbetare var ett jobb bara för starka unga killar. Men jobbet var farligt. Det hände många olyckor. Luften var dammig och många gruvarbetare blev skadade och fick lungsjukdomar. När det hände kunde männe...

Catholic Bishops screw up again

The Catholic Bishops of England and Wales have an unlimited capacity for making a muck of things. In preparation for the visit of the Pope, they have produced a 32 page booklet called "Heart Speaks unto Heart". Rarely can such a amateurishly produced piece of typography have been printed in such large numbers - at least a million copies, probably more. There was a time when many of Britain's leading typographic designers were Catholics. There is Eric Gill, of course, designer of the famous Sans and Perpetua typefaces. There is Edward Johnson, who designed the sans-serif Johnston typeface that was used throughout the London Underground system from around 1916 until it was re-designed in the 1980s, as well as the famous roundel symbol. There is Stanley Morison, who designed what is probably the world's most-used typeface, Times New Roman. So what have the Bishops given us? A publication that breaks every rule of typography. The recommended length of a line is 2 1/2...

Liturgy problem

Today I went to Mass at a church in a cathedral city in the south of England. It was a children's service and a group were receiving their First Communion, so it was a family affair. I would guess that a good number of the congregation were not Catholics. Good to see a flourishing parish with plenty of young families. But oh, dear, the liturgy was dreadful. We had the notorious "Clapping Gloria", and a collection of the most banal hymns and mass settings composed by I won't say who. We had bidding prayers read by the children, which would have been fine, but some of the children could hardly read. This kind of thing is almost the rule in Catholic churches in Britain. What is the effect of tailoring the liturgy to what adults imagine are children's tastes and needs? The music is actually incredibly dated, being firmly rooted in the early 1970s, before the arrival of Punk. And so once children reach their teens, they regard it a babyish and unsophisticated, as somet...

Class 66 for passenger trains?

Class 66 Diesel Locomotives Nos. 66200 and 66019 at Carlisle , originally uploaded by allan5819 . Rated at 3,300 hp, these diesel locomotives intended for freight services are about as powerful as a Deltic or a four-car Voyager set. Although top speed is only 75mph, they would still give excellent performance on stopping trains with up to ten cars, running on services with stations about 15 miles apart, where there is little opportunity for high speed running anyway. As the locomotives are not normally used for passenger trains they can not provide electric train heating. They would either have to be adapted or the train heating/air conditioning power would have to come from a generator van. Class 66 on passenger train

Steam but not as we know it

The cab of a steam locomotive strike me as an unsuitable environment for a laptop computer but obviously this technology has finally cleaned up its act.

Flags are just bits of cloth but like all symbols they carry meanings that change over time. What does this one mean today?

Hotel power

8911 at Connolly , originally uploaded by rowanC82 . "Hotel power" is the name given to the electrical power used to run things like heating and air-conditioning systems on trains. Each type of vehicle has what is known as an electric train heating (ETH) index. Typically, the power consumption of a modern air-conditioned vehicle is about 20kW per vehicle. The power consumption of each type of stock is expressed as a figure known as the ETH index. Mark 3 stock has an ETH index of 6, stock without air conditioning has an ETH index of about 3. The power to run the heating and ventilation system is normally drawn from the locomotive and with electric traction, the power comes from the overhead line. With diesel traction, it is taken from the traction current generator on the locomotive. In the case of mark 3 hauled stock, the power supply is run down the train via a 1000V DC line. In the case of HST trailer cars the power supply is 415V 3-phase. The locomotive must, of course, b...
