The Lehigh Valley Railroad was a railroad company in the northeastern United States primarily used to haul anthracite coal from Mauch Chunk (now Jim Thorpe), Pennsylvania, to Easton, Pennsylvania. This collection consists of twenty-two glass negatives and one box. Most photographs depict the rolling stock of Lehigh Valley Railroad dating to approximately some point between 1934 and 1948, based on engine numbers.

This collection consists of glass plate negatives and photographic copy prints which were made directly from the negatives. The images document an array of subjects, though the majority of the images are of locomotives, railroad cars, railroad stations, and other railroad infrastructure. Various landscape and cityscape photographs are also included. Where it is possible to identify the locations, the majority of images document sites in Pennsylvania, though photographs of sites in New York state and Ontario are also present.
