I'm using the RTE station as opposed to BOS proper. Driving would still be faster/cheaper in general. But then I'd have to drive into Manhattan.

It makes me so mad that we have a rail system that has all the structural necessities to make HSR a reality, yet we're stuck with service that last looked modern 50 years ago. If there's one place in the USA that would have the ridership to support a HSR it would be the Boston-DC metro axis.
