This long-awaited study, the magnum opus of a leading railroad historian, describes the conception, construction, and early operation of the first narrow gauge railroads in northern California. It is lavishly illustrated by some 600 photographs and drawings, almost three-quarters of which have never before been published.

The topic is approached through an unusual lens: the history of the relatively small but extraordinarily inventive contracting and engineering firm of the brothers Thomas and Martin Carter. The Carters were able to reduce the cost and complexity of light railroad construction to the point where local narrow gauge lines could initially compete ...

Pioneering a mobile manufacturing operation that could supply locally funded short lines with rolling stock (which traditionally came from East Coast manufacturers), the Carter Brothers began with a line to serve Salinas Valley wheat farmers, desperate to achieve an independent means for conveying their crops to the wharf in Monterey. The narrow gauge railroad that resulted was an act of political and economic defiance, but ultimately a hopeless assault on the "Octopus"—the Central Pacific and Southern Pacific Railroads.

Rallying around the example set in Monterey, a narrow gauge movement in California flourished in the mid-1870s, with the rapid launching of five more companies—the North Pacific Coast, the Santa Cruz Railroad, the Santa Cruz & Felton, the Nevada County Narrow Gauge, and the South Pacific Coast—all of which drew on the Carter Brothers for manufacturing and engineering. Soon, Thomas and Martin Carter were not only selling railroad supplies and engineering to all six short lines, but had won management positions with the strongest, the South Pacific Coast. Until personal and financial disaster overtook them in 1880, the Carters were at the forefront of not just a new business, but a new technology.
