With the LIRR Expansion Project poised to increase capacity, what’s going to provide all the extra power needed to run those additional trains? Traction substations, eight of them to be exact, are in various stages of construction and will deliver the power necessary to accommodate the added electrical load.

“Substations are integral components of the rail infrastructure system that provide power to the trains,” said Tom McGuinness, Project CEO who is managing the Expansion project. “The eight substation replacements for the LIRR Expansion Project are part of a larger initiative to enhance service reliability and support system expansion throughout the LIRR, and ultimately support the growth and development of Long Island.”

There are 104 substations on the LIRR across all areas of the Rail Road’s electrified territory. At each of these substations, AC voltage is converted to DC voltage and safely fed to the third rail out on the tracks. This electrical power then energizes each train’s traction motor, which propels the train.

Substations are strategically replaced as part of every capital program, typically based on age and/or state of good repair. Substations may also be upgraded or replaced as part of a larger project initiative, such as the LIRR Expansion Project.

MTA Construction & Development is currently working to replace substations in Floral Park, New Hyde Park, Garden City/Garden City Park, Mineola, Carle Place, Westbury, New Cassel and Hicksville.
