What would modern rail service look like between Boston and Springfield? What kind of trains would run on such a route?
#TrainTwitter
Local trains calling at every station will require top-notch acceleration to mitigate the amount of time spent at stops, but low top speed.

Intermediate services--rapid, express, etc--can be a little more gentle with acceleration, need a higher top speed, for more cruising time.

The fastest services, skipping most stations, can have the most forgiving acceleration, in exchange for the highest top speeds.

So long as I'm treating this corridor in ideal terms, it's worth adding that it ought to be electrified, and to run MUs (except for freight)

All trains used as examples run on standard gauge track, which is used between Boston and Springfield

I would love to compare specs with current EMUs on, say, the Red Line, but am having trouble finding that information...

Overall, an average speed target of 60mph is about right. That translates to a 1h 40m trip between Boston and Springfield.
