The Hillside Facility, also called the Hillside Support Facility or the Hillside Maintenance Complex, is a maintenance facility of the Long Island Rail Road (LIRR) in Hollis, Queens in New York City. The Hillside facility was built between 1984 and 1991 on the grounds of a section of Holban Yard (see below). The facility covers 30 acres (120,000 m2) east of the former Hillside station and can maintain 60 cars at a time.
The facility includes a station which is the first stop along the Main Line of the LIRR east of Jamaica station. Like the Morris Park Facility west of Jamaica station, the Hillside Facility station is for LIRR employees only.
