FrontRunner is UTA’s commuter rail system. Trains run from Pleasant View to Provo along an 89-mile corridor and serve a total of 16 stations in Weber, Davis and Salt Lake Counties. Stations allow riders to connect to TRAX and bus routes, and most also feature free rider parking and bike lockers.

FrontRunner currently operates Monday through Saturday, with 30-minute frequency during peak times. Fare must be purchased before boarding at an on-platform ticket vending machine or UTA customer service location. Riders can also pay using FAREPAY cards or other forms of electronic payment by tapping the card on the card reader before boarding and after exiting the train. FrontRunner fare is good for two hours after first boarding, and includes free transfers to bus or TRAX during that time.

FrontRunner trains use diesel-powered push/pull locomotives and can reach speeds of up to 79 miles per hour. Each train includes a locomotive and three or four bi-level and single-level passenger cars. FrontRunner trains typically have one car designated for cyclists and bikes. Every FrontRunner train is equipped with complimentary Wi-Fi.

FrontRunner opened stations between Salt Lake City and Ogden in April 2008. An additional station in Pleasant View opened later that year. In December 2012, UTA expanded FrontRunner to include stops between Salt Lake City and Provo.
