O'Hare Transfer station

O'Hare Transfer is a commuter railroad station along Metra's North Central Service that serves Chicago's O'Hare International Airport. The station is 18.6 miles (29.9 km) away from Chicago Union Station, the southern terminus of the line. As of 2018, O'Hare Transfer is the 183rd busiest of Metra's 236 non-downtown stations, with an average of 113 weekday boardings. The station is located at the dead end of Zemke Boulevard east of Mannheim Road (US 12/US 45) outside the northeast corner of the airport's Multi-Modal Facility (rental car/parking lot).

The railroad station is connected to the Airport Transit System people mover at the O'Hare Multimodal Facility. Two Pace bus routes also stop curbside at the lower level of the ATS station. The free ride on the people mover provides a connection to all four of the airline terminals.

As of February 15, 2024, O'Hare Transfer is served by 12 trains (six in each direction) on weekdays.

Owing to the weekday only operation and limited frequency typically offered by the North Central Service, the station is not usually a significant means of access for travelers to O'Hare. All trains are scheduled to stop at the inside (westernmost) platform, but occasionally an announcement will be made over the public address system that a train will be stopping on the outside (easternmost) platform.

Metra offered an expanded schedule for the 2024 Democratic National Convention from August 12–30, 2024. On weekdays, in addition to regularly scheduled service, there were 15 hourly round trips between O'Hare Transfer and Union Station, with stops at River Grove and Western Avenue. On weekends, there were 16 hourly round trips serving the same stations, with no service north of O'Hare Transfer.
