It was built at the railroad's Juniata Shops.","why_significant":"The nomination describes it as a fine and only surviving example of the Class A5 switchers, one of a group of 47 built at Juniata Shops. It is part of a thematic group of Pennsylvania Railroad rolling stock nominated for representing the variety of historically significant rolling stock, many of which are the only surviving examples of their types. The form notes that the cars and locomotives are genuine, not replicas.","narrative":"Switcher No. 94 is a steam switching locomotive, Class A5, 0-4-0 wheel arrangement, built at the Pennsylvania Railroad's Juniata Shops in January 1917. Steam switchers had appeared on the railroad's roster around the time of the Civil War, and the A5 was one of several designs used. Forty-one were built in 1916-17 and six more in 1924, making 47 in the class. The engine has 20-by-24-inch cylinders, 50-inch drivers and a steam pressure of 185 pounds. Its specially designed tender was sloped to give the crew a clear view to the rear, but it carried only 5,700 gallons of water, which made the arrangement uneconomical. Most of the class worked along eastern waterfronts, especially at Philadelphia. Switcher No. 94 is the only surviving example of the class, which is why it was listed as part of a group of railroad rolling stock.","period_of_significance":null,"architect_builder":"Juniata Shops, Pennsylvania Railroad","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 17:11:33.831165-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79002281.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79002281/023ddf5209-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79002281/023ddf5209-1600.webp","licence":"CC BY-SA 3.0","author":"O484","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Pennsylvania_Railroad_94.JPG\" rel=\"noopener\">O484</a>, <a href=\"https://creativecommons.org/licenses/by-sa/3.0\" rel=\"license noopener\">CC BY-SA 3.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Pennsylvania_Railroad_94.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993155","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q79449255"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lancaster-county/switcher-no-94-79002281/"}
