LIRR: Buses replace weekend trains at Ronkonkoma

Buses will replace trains this weekend between Ronkonkoma and Central Islip on the Long Island Rail Road, the railroad said.

The work from late Friday to early Monday calls for switch installation and related track work for the double-track project, the railroad said.

Riders to or from Ronkonkoma should plan for at least an additional 23 minutes of travel time or consider using the Port Jefferson Branch or Montauk Branch as alternatives, or take advantage of free parking at Brentwood and Deer Park, the LIRR said.

The LIRR issued this advisory:

  • Eastbound riders traveling to Ronkonkoma from stations in New York City, Nassau County or western Suffolk County will board their regularly scheduled Ronkonkoma-bound trains and get off at Central Islip to connect with buses traveling to Ronkonkoma. Customers should plan for up to an additional 23 minutes in travel time.
  • Customers traveling to Medford, Yaphank, Riverhead, Mattituck, Southold or Greenport will board their regularly scheduled trains (the 9:12 a.m. or 2:12 p.m. departures from Penn Station) and get off at Central Islip to connect with buses traveling to Ronkonkoma.
  • At Ronkonkoma they will connect with trains making all stops to Greenport. The trains from Ronkonkoma will be timed to meet the buses and will arrive at all stations 23 minutes later than normal.
