Mooted: An Undersea Link From Finland To Estonia 149

jones_supa writes A train link between Finland and continental Europe could become a reality 15 or 20 years from now. A study carried out by Sweco Consulting recommends moving ahead with negotiations on building a railway tunnel between the capital cities Helsinki and Tallinn. According to a preliminary report out Wednesday, an undersea link would shorten the travel time between the two capitals from the current minimum 90 minutes by ship to around 30 minutes by rail. Estimated ticket cost is about 40 euros. The study, commissioned by the two cities, estimates that the undersea route could be completed after 2030 and would cost somewhere between 9 and 13 billion euros.

      It isn't a captive market, competition from the ferries should keep it down. A return ferry ticket is about €50. While you could charge a premium for business class seats, they alone won't fill a train. The Eurostar London-Paris service is a reasonable comparison. Booking in advance, you can usually get a return ticket for that for £100 in off-peak hours. The Dover-Calais ferry is cheaper, but way more inconvenient.

          True to a point but incomplete as your total cost of flying has to include travel to/from the airports on either side as the airports are not in the city proper as the train stations are.

Massively upgrading slow speed networks (as in ~100 mph and more on good tracks) with most of them electricity powered might be a good way to spend the zillions. Frequent runs, more places it goes too, cheaper fares, fuller trains, wifi/4G and maybe USB power for the people married to their phones and then who cares if the trip takes 5 hours instead of 3.

          I'll use the cost to build California's "High Speed Rail" system as an example. It would be cheaper, and more effective, to offer every man woman and child in California, 20 free round trip tickets via Airlines, and that is before a single train is run. The estimated one way price (as of today) is approximately $20 more than the cheapest flights available (and doesn't include ongoing government subsidies)

          So you're suggesting using heavily subsidized airlines instead of rail? Without government subsidizes airline travel would be much more expensive, just think of the price of building and operating an airport as well as the market power the private airports would have with their own airline.

            Source? I would be interested if you're talking about actual subsidies (government giving money to airlines) (and apart from EAS) rather than tax breaks and such. What is the cost per passenger?

            As a libertarian, I'm generally opposed to REAL subsidies for just about everything, simply because of all the unintended consequences.

            • Airlines are supported in several ways. One is that they pay less fuel tax [wikipedia.org]. Then there are the bailouts [go.com] that they get every now and then. The tax breaks [bizjournals.com] that they give to airports. Not to mention incentives [wsj.com], grants, funding, etc to airports.

              • "Subsidized" doesn't mean "Pay less". It does mean "given money to, by the government".

                And I love how keeping money you earn is considered "subsidy" by the left, as if government has the right to all of your money, but allows you to keep some of it. Good job guys.

        Don't confuse Top Gear and real life - that won't end well for you. Train travel in (continental) Europe is a far different beast to that in the UK. Fast, clean, affordable, punctual trains serve every city/large town, with regional routes connecting them to the smaller towns and villages.
      • The reason they could make this happen is because the EU passed a stupid law that says all cars have to be recycled. Before that happened, old cars were taken to the scrapyard to get payment for the salvageable parts, but now people have to pay a hundred quid (according to Clarkson) to have them recycled.

        Hence, a sudden infusion of cars that would have otherwise been scrapped. It has no real-world bearing on th e cost of rail versus car transport, just an inconvenient problem created by the meddling EU.

    • I really don't think it could be cost-effective.
      The distance involved is greater than the Channel Tunnel, and neither Finland nor Estonia has a large enough population to make it worth that much expenditure. There is no way passenger figures will match those of the Channel Tunnel and that particular project ended in tears for investors.

      Because machine lines the tunnel behind it as it drills and moves forward, and because construction continues behind it... meaning they couldn't be "just run forward" as the tunnel ahead was larger than the machine. So they either have to be entombed (as the British did) or dismantled and scrapped (as the French did). Most large TBM's are also custom built, so there's little resale or reuse value to begin with.

      Though to be fair, Russia is doing its best to write itself out of Europe... well probably there are trains to Sweden as well.

      What's interesting is how Europe is such a hodge-podge of countries, with almost as many sets of countries as the number of countries:

      There is Europe as a continent - but many countries, esp. Russia really behave in un-European ways; some countries have minority land in Europe (Russia, Turkey).

      The EU seems to be the biggest ensemble - but curiously, Switzerland, one of the richest countries, is not in the EU and does not appear to bear any of the costs of solidarity and convergence (e.g. helping East Europe catch up); also is absent Norway (also one of the richest countries, and a great oil power); and the UK is on the brink of exiting the EU (and the UK now has a weird anti-Eastern European immigrant stance while it happily accepted immigrants of more radically different cultures and London, like Paris, is becoming a Muslim city). Some countries, like Turkey and probably Ukraine will spend an eternity in the waiting room before being able to join. Iceland just suspended joining talks.

      The UK deserves its own section as they are an oddball in many other regards: driving on the left side of the road, using incompatible power plugs, often using imperial units etc. etc. - but more importantly they use terms like "We visited Europe last Summer" as if the UK wasn't even part of Europe. So one of the strongest military powers in Europe is also one of the least integrated (similar in that regard to the Swiss). Germany also deserves special mention due to their strong economy, yet no military power or participation, and the weird stance on nuclear power plants (despite the fact that they are densely surrounded by nuclear power plants). However, Germany is the most important integrating force of Europe, mainly responsible for its Eastern opening.

      Then there is NATO; interestingly Norway is in, but Sweden and (more understandably and regrettably) Finland isn't; Switzerland is again, absent (despite having a strong military; again there seems to be a lack of solidarity while they unilaterally benefitted from being a safe haven and from the tax evasion of the rest of the World)

      Within the EU, there is the Euro currency; while theoretically mandatory for all countries, this further fragments Europe, along multiple fracture lines:
      - Some developed countries (UK, Denmark, Sweden) opted out from the beginning (special treatment)
      - Some countries which caught up introduced the Euro (Slovakia, Slovenia, Estonia), but some opted not to (Czech R., Poland)
      - Some countries have been unable to meet Euro introduction criteria, e.g. due to irresponsible borrowing of the Socialists in Hungary till 2008

      A special place is occupied by Greece - they lied and cheated so they gain admission into the Euro zone. Europe has lavishly rewarded their morals by pouring EUR200Bn into Greece over a year or two. (In comparison, Hungary, which has the same population size but much lower GDP/head and welfare, only got EUR20Bn, i.e. one tenth of that, from EU cohesion funds over around 10 years.) and the Greeks will want more money for their irresponsible behavior. So some of the European fault lines are growing and the Euro zone is about to shrink. But of course Europe doesn't try to offset the loss of Greece by more ambitiously integrating Eastern Europe like Poland, the Chech Republic and Hungary. In fact, Bulgaria, Hungary and Slovakia has been left by the EU to predominantly depend on Russia for energy sources, a BIG mistake with the reversion to Russian imperialism.

      Minor redemption is the SEPA (Single Euro Payment Area), which, despite its name, includes a lot of non-Euro, non-EU countries. SEPA's spirit (removing financial friction inside Europe) and existence however doesn't stop a UK bank like Barclays to shamelessly charge a whopping GBP25 fixed fee on each and every transfer (despite electronic, STP) into another SEPA country.

The Baltic states have cultural ties to Finland. The only other overland route to the EU is by Poland but this is stuck between Kaliningrad and Belarus.

    Each time we do this, we tunnel (at great cost) under the ocean floor. While the engineering involved is impressive, I can't help but wonder why we don't just build a tunnel on the sea floor (by manufacturing the materials on dry land and then just sinking them to the bottom and sealing them up). Is the problem that we don't have the submersible technology, or robotic technology to do the finishing work, or is there something else I'm missing?

    This can't be the best way to build a tunnel through the water.

      Some drunk driving a motorboat with the anchor dragging above the ocean floor will latch on to above ocean floor tunnel, causing a massive leak and/or damaging the boat. This is why it's better to build the tunnel in bedrock.

      I'm no expert on it, but I imagine it's because the sea bed isn't particularly flat, so lots of support structure would be needed in order to make a road that's somewhat flat and that's difficult to do under water. Going beneath everything ensures there's a solid foundation the entire way.
    • That's called an immersed tube tunnel. The way it's done is they dig a trench at the bottom, lower concrete tunnel elements to form the tunnel and then cover the structure with rock and sand. This method has been used many times in the past and will be used in the future, for example here: http://en.wikipedia.org/wiki/F... [wikipedia.org]

      Immersed tunnels aren't always cheaper than boring or blasting through rock. For one thing, it is cumbersome and expensive to dig a trench in deep waters.

    • Because a bored lined tunnel is orders of magnitude easier and cheaper at any kind of depth. They are also lower maintenance and will last for a longer period of time. Concrete and sea water don't mix well. This is even assuming that sea floor is nice and smooth and even with no large changes in height.

    • In a tunnel you have air.
      Workers can just walk around.
      We have experience in making tunnels since millennia.
      We make nice tunnels with high tech machines all over the world in mountains.
      Making a tunnel below sea level is no much difference.

      Dropping pipes to the ground of the sea and evacuating them is something different.

    Why would I travel frequently when I can send packets? When looking ahead 50 years should probably worry more about the Singularity than about if people can use transportation in exactly the same fashion they do today.

  • I wonder why the train trip is supposed to take so long, or how the ferry trip is calculated.
    It is a no brainer that the train can be up to 10x as fast as the ferry. So what is wrong here?
    They use hydrofoils for the ferries? Then it makes sense.

    • Big ferries take about 4 hours to cross the gulf (70 km). The 90 minutes mentioned in the summary does indeed apply for newer hydrofoil boats which have max speed about 70 km/h and take little or no cars on board (and have more expensive tickets). The number mentioned for the train (30 minutes) is 8 times less than for large ferries.
      • That makes sense!

        I'm looking forward to be sailing in that area next year in late summer. I guess it will be great fun!
