After crossing under the on-ramp from 17 to the Thruway and passing Woodbury Commons the line gradually moves away from the Thruway, crossing NY 32 and running along the shoulder of Schunemunk Mountain, where it twice is crossed by hiking trails. At Schunemunk's north end it curves along to the Moodna Viaduct, the highest and longest railroad trestle east of the Mississippi River. Immediately afterward it crosses NY 94 and arrives at Salisbury Mills-Cornwall in the Town of Cornwall.
