There is just one passenger train a day that runs down the length of the Valley. Assuming the train is on time, which it often isn’t, it takes two hours and nine minutes to get from Brattleboro, Vt. to Springfield, Mass. That’s an average speed of 27 miles per hour. (The train makes just one stop, in Amherst.) Driving from Brattleboro to Springfield usually takes under an hour.
