I've done up a multi-page web site on an alternative to the proposed Green Line extension into Somerville and Medford. I'd like to get some feedback, and/or otherwise promote it. The alternative isn't dissing the use of the Green Line, merely making better use of it than the GLX will do. The current price tag for the GLX is a mind boggling, highly exorbitant expenditure for a short extension of a light rail tram in an already owned rail corridor.
There are no words to describe the size of the ripoff that is the GLX. For $10 billion the Swiss bore TWO tunnels, each 30' wide and 35 miles long, yes, 35 MILES, through the mountains, TWO of em. The price tag actually includes another 24 miles of connecting and support tunnels. The tunnels are sized for HIGH SPEED trains to be traveling at well over 160 miles an hour (which is the minimum in the EU for high speed rail).
