The structures and objects series is the largest series in this collection. It includes images of the buildings affiliated with railroads, excluding passenger stations from 1904 through the 1970s. Several different railyard locations throughout Pennsylvania, New Jersey, and Delaware make up the bulk of this series, with the specific names of houses and sheds described. These railyard houses include freight houses, engine houses, oil houses, tool houses, storehouses, bank houses, rest houses, etc. This series also contains Railyard shops, including carpenter, blacksmith, paint, and locomotive shops. Images that Weer did not describe and could not be identified have been grouped together based on architectural similarities. The various bridges that served the Reading Railroad and other neighboring railroads are found in this series. Some bridges are identified by an explicit name, while others are identified by location or number. Aerial views of cities, railroad lines, and railyards are organized within the structures and objects series. There are images of objects that may have had a direct connection to the Reading Company structures. Some of these objects are pieces within a specific house or shop. Others are machinery, and still, others are logos or decor for the Reading Company.
