The Green Mountain Flyer was an international day train between Montreal, Quebec, Canada, and the Northeast United States, with sections to New York City and Boston. It was operated in cooperation between the Rutland Railroad, the Canadian National Railway and the New York Central Railroad. The train carried the number 65 running north, and number 64 running south. The Mount Royal (#51 north, #52 south) was the night train counterpart to the Green Mountain Flyer. Following years of cutbacks, both trains were discontinued in 1953 when the Rutland Railway ended all passenger service.
