The station has one four-car-long high-level side platform with two waiting shelters to the east of the track.[3]: 25 The platform is situated between the grade crossings of Glenbrook Road to the south and Crescent Street to the north.[4] There are no ticket machines.[5]
Glenbrook was formerly served by two stations – one on the New York–New Haven mainline, and one on the New Canaan Branch. The mainline station, located at Courtland Avenue, was closed in the early 1970s. The station has been unstaffed since January 15, 1972.[6]
In 2007, city officials were considering the idea of building a second train station in the area, possibly at the original mainline station site.[7] In December 2010, Connecticut Governor M. Jodi Rell announced that the state Bonding Commission was expected to approve $950,000 in financing for a canopy.[8]
