OnTrack was a Syracuse, New York Regional rail line. During its operation, Syracuse was the smallest city in the Unite States to have regional train service. The line ran from Colvin Street on the city's south side via Syracuse University and Armory Square to the Carousel Center, using three Budd Rail Diesel Cars that were built in the 1950s. There was also a flag stop called 600 Erie Place, and seasonal service to Jamesville. Financing was approved in April 2004 to build a bridge that would allow OnTrack to reach the William F. Walsh Regional Transportation Center, Regional Market, and Alliance Bank Stadium. These stations have already been built, and most of the track has been laid, with simply the bridge link missing.
