LIRR to Replace Switches in Peconic on Dec. 12
Buses to Substitute For Trains Between Ronkonkoma and Greenport

The Long Island Rail Road will replace switches at Mill Road in Peconic on Tuesday, Dec. 12, in an effort to improve service and reliability along the Main Line stretch between Ronkonkoma and Greenport as part of the Mill Road Switch Replacement Project. The LIRR is committed to minimizing impacts on our customers as it performs necessary infrastructure upgrades by scheduling the work midweek to lessen disruptions to the East End during the weekend.

Beginning Tuesday, Dec. 12, the single main track will be taken out of service between Ronkonkoma and Greenport after the arrival of the 5:30 a.m. train from Greenport at Ronkonkoma at 6:53 a.m. Regular train service will resume between Greenport and Ronkonkoma the morning of Wednesday, Dec. 13.

To allow for this work, which is taking place on the track west of the crossing at Mill Road, four eastbound trains and four westbound trains between Ronkonkoma and Greenport will be cancelled on Tuesday, Dec. 12. Bus service will be provided on this day to accommodate customers who are traveling among Greenport, Southold, Mattituck, Riverhead, Yaphank, and Medford stations to connect to regular train service that will run between Ronkonkoma and Penn Station.
