When Cleveland Union Terminal was built, the train station allocated the northern set of tracks for interurban or rapid transit service and the southern set of tracks for inter-city rail service. The portion of the station above the interurban tracks was called the Traction Concourse and the portion above the intercity train tracks was called the Steam Concourse. The Van Sweringen brothers envisioned a network of interurban lines extending from the CUT in all directions. They even acquired right-of-way for some of the lines.
