No problema! Just buy a VIA ticket from Toronto to the Border (Amtrak will handle Booking/Ticketing for you), and Book your AGR Award from the Border to NYP! As you may know this is a VIA Train on Amtrak Equipment between Toronto and Niagara Falls, Ontario, then a Crew Change is done @ the VIA Station and it becomes an Amtrak Train to NYP! Customs and Immigration is done Inside the Niagara Falls, NY Station after Crossing the Border!
Amtrak has Business Class on this Train (the Nice 2x1 Seating in Half the Cafe Car) but VIA doesnt but they only charge $1 to ride in this car between Toronto and the Border if you have a Biz Class Seat from the Border to NYP!!The Food and Drink in the Cafe uis changed out during the Crew Change and VIA Sells Coke Products, Amtrak Pepsi only!
