Long Island Rail Road (LIRR)

Long Island Rail Road (LIRR)

The Long Island Rail Road is the nation's largest commuter rail by ridership, shuttling an average of 337,800 passengers every weekday between Long Island, Queens, Brooklyn and Manhattan.

The LIRR is in the midst of several major improvement and expansion projects, which include:

  • Double Track – 12.6 miles of additional LIRR track between Farmingdale and Ronkonkoma that will ease congestion and promote both traditional and reverse commuting.
  • Third Track – an additional track from Floral Park to Hicksville will reduce delays due to service issues, promote a reverse commute and spur economic activity.
  • Electrification – extending electrification of three LIRR lines further east for faster, more reliable, uninterrupted peak and off-peak travel.

Reimagine Transit: Suffolk County Mobility Implementation Plan

The Reimagine Transit initiative, led by the Suffolk County Economic Development and Planning Department in partnership with the Department of Public Works, aims to redesign Suffolk County’s fixed-route bus network and identify opportunities for the use of new mobility tools, like on-demand transit services. This initiative is a chance to rethink the entire network of routes and ensure that the County is making the best use of its resources and aligning its transit investments with community goals and priorities. More information on this initiative including project goals and timeline, and opportunities to get involved can be found here.

The study further outlines strategies and actions for improving mobility to ensure Suffolk County is well positioned to support existing riders, attract new riders, enhance economic competitiveness, support vibrant communities, leverage investments, and provide a foundation for sustainable growth in the County while reducing reliance on personal vehicles.
