Alaska To Siberia... By Rail?

SlushDot writes:This article describes an unbelievably ambitious project that would make the "the chunnel", the underwater tunnel connecting England and France, look like a high school science project. Russia wants to build a tunnel from Eastern Siberia to Western Alaska, right under the Bering Sea. At a projected cost of 1.7x10^12 Russian Rubles (That's 4x10^10 GBP or $6x10^10 USD), I'm not sure where Russia will get this money, but wouldn't it be fun to ultimately travel from Tierra del Fuego to Johannesburg by train?"
