About the project

Long Island Rail Road service to Manhattan's east side is now a reality.

The culmination of the East Side Access project will be the opening of Grand Central Madison, a new terminal along Madison Avenue between 43rd and 48th streets that will accommodate LIRR trains. This new service from Long Island to Grand Central will save commuters up to 40 minutes of travel time per day.

Approximately 45% of Long Island Rail Road commuters are expected to go to Grand Central Madison, so there will be less crowding at Penn Station and the surrounding subway lines. The new service to Grand Central will increase peak hour capacity, and — in combination with the Double Track and LIRR Expansion Project — will make true reverse commuting between Manhattan and Long Island a reality.

When the project is complete, trains at Harold Interlocking, a railroad junction that serves both Amtrak and Long Island Rail Road, will be able to pass through more efficiently. This will benefit travelers all along the Northeast Corridor. The project will also expand and strengthen the regional rail network, protecting it from future transportation crises.

Project benefits

  • A direct connection for all 11 LIRR lines to Grand Central Terminal and Midtown East

  • A new, 350,000-square-foot terminal with spacious waiting areas, retail and restaurants, real-time departure information, and free Wi-Fi

  • Over 160,000 passengers per day will save as much as 40 minutes on their trips

  • Two new tunnels that will increase train capacity to and from Manhattan by 50%

  • Less crowding at Penn Station

  • Improvements to and expansion of Harold Interlocking, a critical piece of the Northeast Corridor
