High speed in New England in the 1970s meant these turbine-powered trainsets built by United Aircraft, which sprinted between Boston and New York from 1969 to 1976. The two Turbotrains (Amtrak later bought a third set from VIA Rail Canada) achieved the route’s best-ever timings — 3 hours and 48 minutes between Boston and New York with four intermediate stops — but reliability problems ultimately doomed the equipment.
