Construction for Double Track Project on June 24-25 to Improve LIRR Service; Buses to Substitute for Trains at Central Islip and Ronkonkoma
Trains Will Connect With Buses at Brentwood

Buses will substitute for Long Island Rail Road trains at Central Islip and Ronkonkoma on Saturday and Sunday, June 24-25, in order to allow crews to conduct critical work to advance the LIRR’s Ronkonkoma Branch Double Track Project, which will improve train service and allow greater flexibility to minimize the impact of service disruptions along the branch.

The Double Track Project is a $387 million infrastructure project, funded over two capital programs that will add a second track to the 18-mile stretch from Farmingdale to Ronkonkoma by the end of 2018. The work on this weekend calls for switch installation and related track work for the Double Track project.

“This is a major capital project bringing major long-term benefits to the LIRR,” said LIRR President Patrick Nowakowski. “A second track between Farmingdale and Ronkonkoma will increase train capacity and reduce disruption-related delays. But to reach the point of completion on the project, we need to temporarily impact service. We’ve worked hard to plan this weekend outage so that it will impact the fewest customers possible.”

Buses will substitute for trains at Central Islip and Ronkonkoma for 48 hours on Saturday, June 24, and Sunday, June 25. Customers traveling to or from Central Islip or Ronkonkoma should plan for up to an additional 34 minutes of travel time, or should consider using the Port Jefferson Branch or Montauk Branch as alternatives, or take advantage of free parking at Brentwood and Deer Park.

Trains will run between Ronkonkoma and Greenport, but customers traveling between points west of Central Islip and Medford, Yaphank, Riverhead, Mattituck, Southold or Greenport will connect between trains and buses at Ronkonkoma and Brentwood. These customers should plan for up to an additional hour of travel time.
