Buses to Substitute for Weekend Trains Between Ronkonkoma and Greenport


To accommodate ongoing work by the Suffolk County Department of Public Works to replace the bridge that carries Horseblock Road over the Long Island Rail Road's Ronkonkoma Branch in Medford, the LIRR is advising customers of service changes for the weekend of Nov. 7-8.

Beginning on Friday, Nov. 6 at 11:20 p.m., the single track between Ronkonkoma and Greenport will be taken out of service to support the bridge replacement work. The track will be back in service by 3 a.m. on Monday, Nov. 9, with no effect on the morning rush hour expected.

As a result of the work, buses will substitute for trains between Ronkonkoma and Greenport. Customers are advised to plan for an additional 30 minutes of travel time at affected stations east of Ronkonkoma.

A complete bus and train schedule can be found in PDF format at this link:

Below is a summary outlining the alternative service.


Customers at Medford, Yaphank, Riverhead, Mattituck, Southold or Greenport will find buses at station that will connect at Ronkonkoma to regularly scheduled train service to Penn Station. Buses will depart from these stations up to 30 minutes earlier than normal train departure times. Customers are advised to plan for additional travel time.


Ronkonkoma Branch trains will operate on their normal times between Penn Station and Ronkonkoma. At Ronkonkoma, customers seeking to travel to all further stations will be able to board buses for continuing eastbound travel.

Customers boarding in New York City who are seeking to travel to Medford, Yaphank, Riverhead, Mattituck, Southold or Greenport should plan to arrive at their origin station one hour earlier than normal.
