When the wind blows, the trains stop

For the second time this week, trains on many routes in the west of Sweden have been cancelled due to high winds: this happened on Sunday morning (7 July) and again this afternoon (10 July).

Apparently there is a risk of trees falling on the overhead electrification cables, and of the cables themselves getting blown down. The cables come down regularly; a couple of times a week, it is said. I have personally been caught up in two incidents. In the first, the train was stuck in a forest for four hours when the wires came down. This was on a lovely afternoon in July and passengers could enjoy the sun and opportunity to walk their dogs. The stay in the forest was so long because it took two hours to couple a rescue locomotive to the train. A month ago the passengers were ordered off a Copenhagen to Gothenburg train because the wires had been stolen, and that journey ended up with an overnight stay in a hotel.

Which raises two questions. Why are trees allowed to grow where they are an obvious hazard? In steam days the trackside had to be kept clear because of the risk of fires. On electrified lines, the risk of disruption due to trees falling on the track is even greater.

The second is why are the lines electrified at all? Now that electricity is priced on the Europool market, it is not cheap, and there are many lines where there is not enough traffic to justify the cost of putting up the wires and keeping them in order, which is an onerous task in itself.

Perhaps some of this electrification infrastructure should be removed when it is life expired?

The Zombie Train that refuses to die

The Guardian has published a couple more articles against HS2, one by specialist rail commentator Christian Wolmar, and another today by journalist Simon Jenkins. The main arguments in favour will doubtless be wheeled out by the commentators: the need for capacity and the disruption caused by upgrading existing routes. HST itself will severely disrupt services to Euston during the construction period. Capacity can be increased at a fraction of the cost by a variety of measures, provided that it is accepted that the additional traffic will run at existing speeds. It is not generally known that the Midland main line is, or was, four track all the way from London to Trent Junction, between Nottingham and Derby. This is because the additional tracks are separate, having been added for coal trains which trundled down to Brent sidings, on the edge of London, from a collection point at Toton in Nottinghamshire, where the Midland Railway build a huge marshalling yard. Beyond Derby, the main l...

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...

Beyond electrification

In an earlier post I suggested a core list of lines which ought to be in an electrification programme spread over twenty years of so. This leaves a residue of routes which it is unlikely will ever be electrified. This include for example All lines beyond Glasgow, Stirling and Aberdeen All lines west of Exeter and Swansea All lines west of Chester Shrewsbury - Chester Everything not listed in my previous blog - electrification plans only scratch surface   Some of these routes carry main line services to London and other cities on parts of the network that are already electrified or included in electrification plans. Others are self contained and others carry light traffic - less than a dozen trains a day. The current plan is that main line services will be operated with the hybrid trains on order from Hitachi, but this is a costly, wasteful and ineffective solution. The performance of the trains will be inferior to the present Inter-City 125 trains on non-electrified lines and the ...
