To modernize its aging fleet and support continued ridership growth, the Long Island Rail Road (LIRR) procured 202 new M‑9 rail cars designed to enhance passenger comfort, accessibility and safety. These next‑generation electric multiple units introduce upgraded amenities and advanced safety systems that strengthen reliability on one of the nation’s busiest commuter rail networks. The M‑9 program reflects LIRR’s commitment to providing a better travel experience while meeting the demands of a growing customer base.
What challenges did STV address?
LIRR sought to replace older vehicles with a fleet that offered improved onboard features and streamlined systems integration. Enhancing reliability required careful engineering coordination across multiple subsystems. The project also demanded rigorous documentation, schedule oversight and quality controls to support the successful rollout of the new fleet.
What solutions did STV deliver?
As a subconsultant, STV served as lead engineer for key electrical systems including the automatic door system, auxiliary power system and several onboard power components. The team performed extensive design reviews and monitored adherence to the delivery schedule to ensure seamless integration with LIRR operations. STV’s work supported the development of rail cars equipped with modern customer amenities such as electronic information displays, push‑button internal B‑End doors and accessible restrooms with no‑touch fixtures. Advanced safety systems, including Positive Train Control and multiple onboard camera systems, further elevate reliability and passenger protection.
How does this project benefit the region?
The M‑9 fleet improves comfort, safety and operational consistency while supporting LIRR’s long‑term mobility goals. Enhanced amenities and modernized systems help deliver a better and more reliable travel experience for commuters across Long Island and New York City.
