This book concentrates on the electric lines of the part of Southern Ontario adjacent to the Grand River (plus a corporate outpost at Woodstock). Naturally fertile and prosperous, this area attracted early settlement which coalesced around two points: the head of river navigation at Brantford, and the waterpower sites at and north of Galt. The latter gave rise to a densely-settled triangle bounded by Galt (which later, with Preston and Hespeler, was incorporated into today's City of Cambridge), Waterloo and Guelph, with outliers to the north at the Elmira and Fergus areas. Such conditions were ideal for the development of local railway transportation which appeared as expected: horsecar lines were built at an early date in Brantford and Berlin/Waterloo, and the Galt Preston and Hespeler was one of the first electric interurban lines in Canada. The vitality of the lines, particularly those in the northerly triangle, was thus established, and it continued for many years. The transformation of the Galt, Preston and Hespeler into the Grand River Railway in the early 1920s was the most complete reconstruction in Canadian electric railway transit history. The book tells the story of the area's streetcars, trolley coaches and interurban railways that provided both local and inter-city passenger, freight and express delivery services to communities such as Guelph, Kitchener-Waterloo, Hespeler, Galt, Preston, Brantford, Woodstock, Ingersoll, Port Dover and many more. It explains how the individual railways began, the politics and economics that impacted their development, their rise and eventual decline. Profusely-illustrated with many rare photos, the book features over 200 images, about 50 of them in superb color. About a dozen maps provide details on where the lines ran, and an equipment list delivers details on the various companies' rolling stock.
