Designed by Alfred M. Hedley from wood and stamped metal, Quincy opened on October 3, 1897.

It retained much of its original surroundings over the years and is considered one of "150 great places in Illinois" by the American Institute of Architects.

Turnstiles for fare payment are located in the station houses on the platform level.

Both platforms are designed to handle eight-car trains, the longest the CTA 'L' system can run.

The renovation added two new elevators to the station to make it accessible for people with disabilities, and other improvements include new stairs and new lights.
