It measures about 46 feet 7.5 inches in outside length and 9 feet 10 inches in width, has a metal roof and four cast iron wheels, and seats 58 passengers, 24 on reversible seats and 5 on fixed seats. Its significance lies in its heating system. It was the first Pennsylvania car to draw steam from the locomotive for heat, which removed the need for a coal stove and allowed four more passengers to be carried. That system remained in use until 1912, when steam vapor heating replaced it. The car is one of a group of Pennsylvania Railroad rolling stock nominated as a thematic resource, and it is among the few surviving examples of its type. It is currently on loan to the Strasburg Railroad.","period_of_significance":"1886","architect_builder":"Juniata Shops (Pennsylvania Railroad)","architectural_style":null,"criteria":[],"status_note":"Currently on loan to the Strasburg Railroad.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:34.263105-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79002270.pdf"},"photo":null,"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993193","wikipedia":null,"wikidata":null},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lancaster-county/passenger-coach-no-3556-79002270/"}
