Frank A. Weer (1932-2019) was an employee of the Reading Company and an enthusiastic photographer of all things related to railroads, specifically in Pennsylvania. Fascinated by trains from a young age, Weer spent time taking photographs of the passing rolling stock. He developed his own photographs, and over time, he established a vast collection of photographic prints of steam locomotives and other rolling stock, as well as the railroad tracks and structures with which the railroad was affiliated. The Reading Company, where Weer worked for thirteen years, was an influential railroad company that served the economic development of the Greater Philadelphia area for over 100 years. Before it became a booming passenger railroad, the Reading Company began transporting anthracite coal. The passenger "ridership" of the Reading Company reached its peak in the 1950s. The company went bankrupt in 1971, and the passenger services were taken over by the South Eastern Pennsylvania Transportation Authority by 1974. This collection documents the construction and expansion of the Reading Railroad and the company's tangible property and human resources throughout the twentieth century. The collection consists of negatives (glass plate and film), photographic prints, and color slide transparencies. The creator established a chronological order, which has been maintained. The collection is arranged into five series: Structures and objects, Passenger stations, Rolling stock, People, and Frank A. Weer's personal slides.

Frank A. Weer (1932-2019) was a white-collar railroad employee who spent most of his career with the Reading Company, and after the transfer of railroad operations in 1976, with Consolidated Rail Corporation (Conrail). This collection is a small portion of a much larger collection of official railroad company documents, maps and drawings. Documents are primarily those of the Reading Company, Pennsylvania Railroad Company, Penn Central Transportation Company and Consolidated Rail Corporation (Conrail).
