Buses will replace trains at the Hempstead and Country Life Press stations for 12 hours on Saturday, the Long Island Rail Road said.
The substitution, from about 1:30 a.m. to 1:30 p.m., is necessary so track workers can prepare for concrete tie installation, according to a news release from the agency.
Customers should expect up to an additional 13 minutes' travel time, depending on destination.
Eastbound travelers on trains scheduled to arrive at Country Life Press in Garden City between 1:30 a.m. and 12:33 p.m., or at Hempstead between 1:34 a.m. and 12:37 p.m., will transfer to a bus or van at Garden City.
Westbound travelers expecting to board trains scheduled to depart Hempstead between 1:49 a.m. and 1:11 p.m., or trains scheduled to depart Country Life Press between 1:52 a.m. and 1:15 p.m., will instead take buses or vans to Garden City for connections to regularly scheduled trains, the LIRR said.
Buses and vans will depart up to 13 minutes before the scheduled train departure times. To catch the buses, customers should arrive at Hempstead or Country Life Press 15 minutes earlier than the scheduled train departure time, the railroad said.
