Would be good for freight, here in Australia we double the shipping containers 2 high on trains once they get to South Aus as there is no bridges/tunnels ect all the way to Perth on the west coast.
And unlike ships trains travel from A to B, people dont realise that most ships will do a loop, eg Singapore, Auckland, Melbourne, Sydney ect over and over. It would get freight to those places a lot cheaper than ship/air, and hopefully be good for the local economies.
Ships don't just go from A to B. They stop at other ports along the way and unload some containers, get new ones put on etc.
Do you really think they will fill giant ships with shipping containers just sending from Russia direct to USA? No. They stop at multiple other locations along the way. That is why it costs so much to freight by sea. Not to mention it takes a long time and shipping by sea is also extremely dangrous.
Just see this - http://www.theaustralian.com.au/news...-1226174190397
Sure, building a tunnel through an area prone to earthquakes isn't any safer. But don't kid yourself, the oceans are extremely dangerous and cargo is lost all the time on ships. Not just when a ship sinks, but from large waves hitting the ship and sending cargo overboard. The ocean is littered with cargo containers.
So in some ways this does make sense. It would be quicker, cheaper and will stimulate economies along the way.
To those saying it won't stimulate the economy in Siberia/Alaska, you're wrong. Ofc it will. First thing first, they need workers to build the tunnel. A project like this isn't made by a small team of people and sourcing local people is much more cost effective than getting people from mainland USA etc. Afer building the tunnel, they need people to lay the track, install the electrics for the signals and any lighting etc. After that, they need people to work at the stations along the way. Just like ships, the trains will also stop frequently to unload and load up with new cargo. This requires workers of all sorts. Especially with the amount of mines in Alaska/Canada, freighting materials from Russia then unloading in Alaska and loading up onto Ice Trucks to freight off to the mines will require more workers.
A similar thing is happening in Australia with our mining boom right now. The local communities near the mines are getting wealthier and wealthier because more and more people are going out to the mines to work. This requires them to be housed, buy food from local stores etc.
Eventually, when they open cut Olympic Dam (will be the largest open mine in the world) it will create around 25,000 new jobs and production will more than triple for some materials they are mining.
So don't kid yourselves, something like this will most certainly stimulate the local economies in Alaska and Siberia.
