The Importance of the Structure
From the Illinois Department of Natural Resources, Historic Sites Division:
The Pullman Rear Erecting Shop (RES) gives evidence to the industrial evolution that defined American mid-19th and 20th century rail car design and assemblies. The RES footprint is witness to the high-bay, long-span structures that facilitated the Pullman industrial engine and supported the assembly of early steel rail car production.
Surviving as the remaining southern book-end of the rear erecting shop buildings, the estimated 38,600 square foot RES structure is composed of solid masonry, multi-wythed brick and limestone walls, gambrel roofs, riveted structural steel column and truss assemblies, over-sized rail car access doors and brick-flooring. The original roof assembly was punctured by continuous and segmented bands of roof monitors designed to maximize interior ventilation and natural day-lighting.
Architectural and decorative appointments, although modest, provided a visual reference to the overall site aesthetic and architectural design conceived by architect, Solon Beman.
