In 1874 the Baltimore & Ohio Railroad constructed a roughly 10-mile rail line from Findlay, Ohio northwest to McComb, Ohio. Around the same time, the McComb, Deshler & Toledo Railroad, later under the control of the Cincinnati, Hamilton and Dayton Railroad, established the rest of the line taking a northwestern route from McComb to Deshler passing through the town of Deweyville. The line from Findlay to McComb was abandoned sometime in the 1980's.
Most all of the right-of-way has been consumed by urban and agricultural development. Some small remnants of the Findlay-to-McComb route are still visible along the power transmission lines or along road grades and small wood lots. A paved rail-trail covers over 2 miles of the abandoned line from Broad Avenue east to Cory Street in Findlay (easternmost terminus) along the Blanchard River. At that point, the ROW is still visible up to the I-75 overpass designating where the route headed northwest out of Findlay. Beyond that, urban development has consumed much of the line west out of Findlay.
