I recommend the route New York To Montreal which it will pass Adirondack Experience spectacular fall foliage in New York's Hudson River Valley on the Amtrak Adirondack. This high-speed train takes you through Upstate New York on a 10- to 12-hour journey along the Hudson River and Lake Champlain, past mansions, forests, and fields, to Gare Centrale Station in Montreal, Canada. Stops along the way include the towns of Poughkeepsie, Saratoga Springs, Whitehall, and Ticonderoga locomotive that I recommend is GE Genesis For further advice You can comment.
The southern segment of Adirondack is an existing route for the sister game train Sim 21. The Hudson Line New York to Croton-Harmon Metro-North station. DTG might need to break this down as Empire Corridor North Croton-Harmon Albany then Adirondack Line North Albany Montreal.
