Ron Newman said:I don't see why a light-rail vehicle in the current Silver Line tunnel would be either better or worse than the current electrified bus of the same size in the same tunnel. And what would you do about the airport access?
For one, it is loud, very bumpy and slow in those tunnels. It offers a rather uncomfortable ride. If anything, the tunnels should be converted for dual use, light rail around the South Boston Waterfront and for buses to the airport.
On a related note, while in Munich back in October, I noticed that buses run in the streetcar reservations, thus seperating them from general traffic (they also had countdown timers at most bus/streetcar stops, but that's another story).
