According to the MTA website, normal service will resume this morning, Aug. 30. The website says:
Metro-North resumed regular weekday service this morning on the Hudson Line, New Haven Main Line, and the Harlem Line to and from Southeast. Metro-North Service on the Port Jervis Line is suspended until further notice because of extensive hurricane damage. The LIRR has restored full weekday service on the Far Rockaway, Babylon, Port Washington, Hempstead, Ronkonkoma, and West Hempstead Branches, as well as west of Huntington. Subway, bus, SIR, and paratransit services are now running normally across the system with limited exceptions on bus routes.
