If Chicago-Champaign-Carbondale, with mostly small online communities except for Chicago and Champaign-Urbana, and a lot of cornfields between them, can support two pair of corridor trains and a share of the City of New Orleans, surely Boston-Worcester-Springfield-Hartford-New Haven-NYP-pts west can support at least so many.
I'm really puzzled by the people here who are just totally convinced that almost no one in Springfield would take a convenient train to Boston or vice versa. There are millions of people living along the route, probably over a hundred thousand living within walking distance of a station, the station cities all have colleges in and close by and at many of the colleges a lot of the students don't have cars and do have friends in some of the other station cities, a lot of people in Boston, New Haven, and Hartford are already used to riding trains daily or occasionally, Boston is a stressful place to drive into and an expensive place to park, I-91 and I-84 are as miserable at rush hour as anyplace else in Connecticut, the Mass Pike is no better and you have to pay tolls, there are decent bus systems to connect to in Worcester, Springfield, probably Hartford--and the T keeps limping along. The route seems as made for train service as any place in the US that doesn't currently have it, and yet two posts back someone admitted there might be a couple hundred potential occasional riders. This is not a proposal for hourly service to Lincoln, New Hampshire, or some other foamer daydream.
