There are only two daily trains: Northbound Q620 (Selkirk-Massena), southbound Q621 (Massena-Selkirk). Both work Norwood and Watertown on the weekdays. There are around 3 Monday-Friday local trains between Massena and Syracuse: B785 (Massena-Canton Turn), B778 (Watertown Based Local), and some B train that's Woodard based (Maybe B773?). Other than that, there's no other trains between that stretch other than random military trains to/ from Fort Drum which run during the spring and the fall.
