Peoria station includes four tracks accessible through three platforms. The platform closest to the entrance is a side platform which allows for boarding southbound R Line trains. There is then an island platform which allows boarding on eastbound A Line trains and alighting from both A Line and northbound R Line trains. The third and final platform is for boarding and alighting from A Line trains bound for Union Station. The island platform and westbound A Line platform require crossing railroad tracks at-grade to access. Additionally, the island platform includes stairs and a ramp between the A Line and R Line sides, as the R Line uses low floor vehicles while the A Line uses high floor vehicles. The station can be accessed via North Newark Street and East 35th Place. There are direct connections into the station's park-n-ride and bus loop.

Peoria station features Biota, an illuminated sculpture created by Blessing Hancock. The art piece was installed in 2016 as a part of RTD's Art-n-Transit program and is located in the center of the station's bus bay. Biota contains LEDs which change color, representing the growth of a living organism.
