Arlington Park station
Arlington Park serves as one of the two commuter rail stops on Metra's Union Pacific Northwest Line located in Arlington Heights, Illinois. Positioned at 2121 West Northwest Highway (US 14) near Wilke Road within the grounds of Arlington Park Race Course, it is situated from Chicago's Ogilvie Transportation Center. Within Metra's fare zoning system, Arlington Park falls under zone 3. In 2018, it was the 15th most frequented station out of 236 non-downtown locations on the network, averaging 1,738 boardings on weekdays.
Initially constructed to provide access to Arlington Park Race Track, the station now additionally accommodates postal workers from the Processing and Distribution Center in Palatine, Illinois, as well as residents of southeastern Palatine and western Arlington Heights. However, connectivity from Palatine is somewhat restricted by a fence. Unlike stations on branch lines, Arlington Park is positioned directly on the main corridor of the Union Pacific Northwest Line. There are no bus routes serving this location.
As of May 30, 2023, weekday service includes 62 trains stopping at Arlington Park (31 inbound and 31 outbound), while Saturdays see 33 trains (16 inbound and 17 outbound), and Sundays have 20 trains (nine inbound and 11 outbound).
Parking facilities are provided within the designated Metra commuter lot inside the track area, managed by Imperial Parking Corporation (Impark). As of June 2010, the daily parking fee was $1.50. Impark has encountered criticism due to additional fees imposed on pay-by-phone transactions when payment machines are out of service.
