Wheaton, located in Wheaton, Illinois, was the western terminus of the Chicago Aurora and Elgin Railroad's main line, after which it split into two branches bound for Aurora and Elgin.
[1] The right of way acquired by the AE&C ended up paralleling that of the Chicago and North Western (C&NW, the modern-day Union Pacific West Line), and it was decided to construct its Wheaton station adjacent to the C&NW's station.
Having been rendered unprofitable by developments in the 1950s, the CA&E closed passenger service on the afternoon of July 3, 1957.
The railroad decided to rent out its stations afterwards; Wheaton was leased to the DuPage County Democratic Party, whose headquarters it served.
Between 1903 and 1914, trains left Chicago alternating between Aurora and Elgin; afterwards, trains proceeded west to Wheaton, where they were split with the front halves going to Aurora and the rear halves going to Elgin.
