East Hampton, Amagansett, and Montauk. Service is infrequent most of the time due to the fact that there is only one track. The easiest time to take the train to the South Fork is on Fridays, when most trains run out of the city, and Sundays, when most trains run into the city, although this sequence also can be applied during morning and evening rush hours. Buses The Hampton Jitney and the Hampton Luxury Liner provide bus service primarily between the South Fork and New York City. Local bus service is provided by Suffolk County Transit. Ferries Direct access between the South Fork and Shelter Island is via the South Ferry (the North Ferry provides access to Shelter Island from the North Fork). Additionally, passenger ferry service runs occasionally between Montauk and Block Island, RI, New London, CT, and Martha's Vineyard, MA.
