Wabash Railroad Reporting mark: WAB

The Wabash Railway (WAB) was a U.S. railway that served the mid-central U.S., the Great Lakes and portions of southern Ontario, just north of Lake Erie. The Canadian leg of its route ran from Windsor to Fort Erie and extended north to Niagara Falls, with stops at all the major communities between Chatham and Fort Erie.

The Wabash shared trackage and stations with the Grand Trunk Railway (GTR). The route became known as GTR-Wabash. After the collapse of the GTR, the route was renamed the CN-Wabash.

In 1964 the Wabash was leased by the Norfolk and Western Railway (later known as the Norfolk Southern Railway). By 1991 it had been fully absorbed into the parent company and ceased to exist.
