Significant Images of Railroading presents an overview of the Center for Railroad Photography & Art's collections. Of the nearly 200,000 images in those collections, 93 are presented here in vibrant color and rich, quadtone black-and-white. Those images come from 10 principal collections, including the work of Wallace W. Abbey, whose circa 1950 photograph from Chicago Union Station is featured on the cover. A preservation award from Trains magazine helped fund processing of the Abbey Collection. Other major holdings include the works of Fred M. Springer, John F. Bjorklund, and Ted Rose. In addition to the Trains award, funding for this publication came from Fred and Dale Springer, the Candelaria Fund, and Bon and Holly French.
