Several east–west routes on the circuit of trains bound east from Chicago through northern Ohio bypassed the city, traveling slightly to the south, passing through Akron and Youngstown, as in the case of B&O and Erie mainlines. In addition, national passenger rail travel had already passed its peak and was starting its gradual decline in favor of the automobile and, later, the airplane. The Erie Railroad, owned by the Van Sweringens, could not afford the electric transfer and continued to use its own nearby station until 1948, when it replaced steam with diesel locomotives and was able to serve the Union Terminal under its own power.
