Publicity photo showing the brand-new Pennsylvania Limited passenger train posing near the Rockville Bridge on the Pennsylvania Railroad (PRR) in 1898. In January of that year, the PRR received four new sets of Pullman Palace Cars in a striking green and creamy yellow paint, supposedly influenced by the presidential train of Mexico's Don Porfirio Diaz. The trains entered service between New York and Chicago and quickly became known as "The Yellow Kid." Note the man in the three-piece suit posing at lower left of no. 174, a D16 4-4-0 locomotive, as well as the engineman leaning out the fireman's window and the man in the open side door of the first car. Just behind the train is the Susquehanna River, which at the time was spanned by the second Rockville Bridge, an iron truss structure carrying two tracks. It was built in 1877 and replaced the first bridge, a one-track wooden structure dating to 1849. In 1902, the third (and current) Rockville Bridge was completed, carrying four tracks across the river with 48 stone masonry arches. It remains a popular photo location and was listed on the National Register of Historic Places in 1975. The photograph is an elevated view of a train on a curve, a style that is now considered classic, especially for action photos. At the time, however, slow films and lenses necessitated stopping the train for the photograph. Note the whispy smoke and steam plumes caused by motion blur during the long exposure. This photo was printed across the inside front cover of Arthur Dubin's book, Some Classic Trains, published by Kalmbach and first printed in 1964.
