The car measures 61 feet 3 inches long.","why_significant":"The nomination describes the car as a typical modern flat car and an example of a type that began in 1881 with the Class FA. It argues that the development of locomotives and railway cars was as important to the Pennsylvania Railroad system as the system itself. The nomination states that the cars in the group are rare survivals and important examples of motive power and railroad car development, and that all are genuine rather than replicas.","narrative":"A flat car built for the Pennsylvania Railroad, numbered 473567, survives in Strasburg, Lancaster County. It measures 61 feet 3 inches in length, a size typical of modern flat cars of its era. The car belongs to a type that began in 1881 with the Class FA, which was 34 feet long and carried 15 to 20 tons. Later flat cars grew to between 50 and 70 feet, with capacities of 70 tons or more. Its importance lies in showing how rolling stock developed alongside the railroad itself. New functions, demands for higher speeds, and heavier loads drove constant refinement of locomotives and cars. Within the wider Pennsylvania Railroad rolling stock group, the car is regarded as an important survivor, and it is recognised as a genuine original rather than a replica. Its listing reflects the value of preserving examples that document this change in railroad technology.","period_of_significance":null,"architect_builder":null,"architectural_style":null,"criteria":[],"status_note":null,"vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:32.304983-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79002267.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993201","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lancaster-county/flat-car-no-473567-79002267/"}
