 A short distance west of the station, trains enter the mile-long (1.6-km) Otisville Tunnel under the Shawangunk Ridge, the longest in the Metro-North system and one of only two outside of the city.There is thus a long siding beginning just west of the station to allow trains to wait if another one is coming through the tunnel the other way, and as a result Otisville appears to be a double-track station.When trains coming the other direction are near, in fact, one will board on the siding via a wooden platform on the tracks (see photo).
