From Suffern, the line follows the same narrow valley as the New York State Thruway and NY 17. The stations at Sloatsburg and Tuxedo are very close to 17 and while Harriman also has its entrance on 17 its actual platform is farther back, adjacent to the Thruway. Harriman is the busiest station on the line. One peak hour train in each direction runs nonstop between Secaucus and Harriman. The Tuxedo station is the one-stop on the line with the original (1883) station house.
