Built as the Wabash Railroad's "Chicago Extension" and an integral part of the shortest railroad between Detroit and Chicago, the Fourth District through Northwest Ohio and Northern Indiana has a colorful history. It was also the first Wabash District dieselized (1950) and home of the last mixed train in Indiana (1962). In addition to an illustrated, researched history, dating back to 1891, Railroading on the Wabash Fourth District tells the story in the words of railroaders that worked the line and folks who remember it. This 320 page hardcover book includes hundreds of photographs, maps, illustrations (some color), diagrams, timetables, track charts, a grade profile, color section, end notes, bibliography and index. As a bonus, the postscript chapter provides an up-date on what happened to the railroad after the 1964 Wabash lease to Norfolk & Western. This includes operations and preservation efforts into the Norfolk Southern era. Railroading on the Wabash Fourth District comes just in time to mark the one hundred twentieth anniversary of the official opening of this line in 1893.
