well, it's not like they don't have train service which they do and is rarely used by Springfielders. and then there is all the bus options which are cheaper than the train and just about as fast. and for folks with their own cars there is the Pike and rte 20.
Beyond all that is there any real demand for expanded train service between Boston and Springfield? Who in their right mind in Boston really wants to go to Springfield? What do you do when you get there?
I'm sure that there are lots of folks in Springfield who want to go to Boston. But do they really want to go there by train? With 100 MPH express service, that might fly. But that's not what is in the offing, and I would have to say that the current combinations of travel options, which in fact includes train service, appears to meet or exceeds the needs jof the Hub trekkers just fine.
