Sounds awesome... but I have no idea how they are going to cross the Bering strait.

A suggestion:

They said about 200 km tunnel under the Bering strait. BTW, the bridge on the picture would be demolished by ice pretty fast... Cool

Constructing a tunnel in the Bering strait? That will be extremely expensive. The 50 km Channel Tunnel cost the British some $8 billion. This tunnel will cost somewhere around $100 billion and $200 billion.

Money estimation of such mega-projects is only one part of the issue. You know, during Great Depression the U.S. government made jobless people busy (and paid them some money indeed) by building roads. So this path has been treaded before (no pun intended)... Grin

I would be surprised if the g-force "problem" weren't solved prior to a hard launch.

The problem is already solved.  It is called limit your acceleration.  It is simple and effective.  The nice thing about a train (as opposed to say a car or plane) is it follows a fixed track.  With a programmed acceleration and deceleration curve, all the g forces over the entire trip becomes deterministic.
