Dubious tunnel project under the Gulf of Finland

Ideas for grandiose infrastructure projects have a habit of refusing to die. One such is for a 50 kilometre tunnel under the Gulf of Finland between Helsinki in Finland and Tallinn in Estonia, priced at £15 billion, including substantial EU funding. It would give a 20 minute crossing time between the two cities, compared to the present ferry crossing times of two to three hours. Also, in the longer term, the idea is to provide Finland with a direct rail connection to the rest of Europe via the proposed Rail Baltica. For this reason, the EU is insisting that the railway is built to standard gauge (1435 mm) despite the fact that both the Finnish and Estonian railways are built to the wider Russian gauge (1520 mm).

Rail Baltica itself is a €6 billion scheme for a conventional speed standard gauge passenger and freight railway from Warsaw to Lithuania, Latvia and Estonia, connecting the three capital cities of Vilnius, Riga and Tallinn. The problem with the route is that the three Baltic countries and Finland are sparsely populated, with a total population of about 12 million in the four countries, with the traffic potential limited accordingly. The same applies to the traffic potential on the route between Tallinn (population approximately half a million, and Helsinki (population about 1.5 million). It is difficult to see how so few people can generate enough travel demand to make it worth building a tunnel between the two cities.

The problem for this part of Europe is that its natural trade hinterland is to the east, outside the EU, but the EU Single Market is constructed so as to discourage such trade.

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 ...
