The sea level terminus of the Otis was just east of the Bogart Road Bridge over the right of way, a mile and a quarter north of Palenville village. Original built on trestle work as detailed in the Otis Engineering articles, the line was rebuilt on fills in 1904 to reduce maintenance costs for the lengthy trestlework. More importantly, the reconstruction work at the base of the mountain allowed for the construction of Otis Junction, permitting the Otis Elevating to receive narrow gauge interchange from the Catskill Mountain Railway and transport them to other Mountain Top destinations via the Catskill & Tannersville.
