There are more reliable ways to get to NYC than the train near Pawling. The train only runs on weekends. There is bus service to NYC at the Rte 17A road crossing in Warwick every hour, 7 days a week. There is train service in Harriman NY 7 days a week. That is about 4 miles north on Rte 17 just before you enter Harriman State Park in NYC. Better yet, hitch south on Rte 17 (or use the pay phone to call a taxi) to Suffern, NY where there is bus AND train service to NYC.
