The facility covers 30 acres (120,000 m2) east of the former Hillside station and can maintain 60 cars at a time.

The line is served by select trains on the Hempstead, Ronkonkoma, Oyster Bay, Montauk, and Port Jefferson branches.

It was built in 1906 and was named for the two communities of Hollis and St. Albans which bordered the yard along the Cedarhurst Cut-Off at the time of construction.

[4] The northernmost segment of the yard extends from the sites of the former Rockaway Junction Station through the grounds of the former Willow Tree Station, which is the present site of the platforms for the Hillside Facility over the 183rd Street bridge,[5] with tracks extending east of the still-operating Hollis Station.

The yard is also used to store a trio of 1950s vintage Osgood Bradley passenger cars.
