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 locomotives to run round trains at terminals, although it would be no bad thing if facilities were more widely available to allow for this. It is unfortunate that these run-round loops were taken out where they were already present - it shows a lack of forward thinking.

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 ...
