I mean, its a jet, right?
The M-497 was a railcar test bed of the New York Central Railroad, developed and tested in 1966. It uses two General Electric J47-19 jet engines, the ones that the Convair B-36 "Peacemaker" used.
On July 23, 1966, the car reached a speed of 183.68 mph, an American rail speed record that still stands today.
