Railroad boxcars are among the most recognized pieces of equipment in the industry, serving as prominent symbols of rail transportation. In the early years, freight was transported on simple flatcars or gondolas. Over time, boxcar design evolved from basic wooden construction with steel bracing to more modern versions. To enhance crew safety, the AAR mandated the removal of roof walks in 1968, requiring boxcars to be updated by 1978 for interchange service. Modifications often involved reducing the height of side and end ladders and lowering the brake wheel. Boxcars are valued for their capacity to transport a wide variety of goods, allowing railroads to operate efficiently by maximizing redundancy.
