It is held as part of the Pennsylvania Railroad rolling stock collection housed in Strasburg, Lancaster County, Pennsylvania.","why_significant":"The nomination argues the locomotive is the only remaining example of its type and a fine representative of the H6 class, which was the workhorse of the Pennsylvania Railroad system. It is described as being in working condition and not overly restored. It is part of a thematic group of Pennsylvania Railroad rolling stock nominated as important to the history of railroading in Pennsylvania and the United States.","narrative":"Built by the Baldwin Locomotive Works in Philadelphia in November 1905, locomotive No. 2846 is a 2-8-0 Consolidation-type freight engine of the Class H6sb. It weighs 93 tons and has 22 by 28 inch cylinders and 56 inch drivers. The H6 design, first produced for the Pennsylvania Railroad around 1899 to 1901, was modified into the wider-firebox H6a and then into the H6b with piston valves and Walschaert valve gear in 1905. Baldwin, Juniata Shops and Alco produced a total of 1,835 H6a and H6b engines between 1901 and 1913. Locomotive 2846 was among those fitted with a superheater, which extended its service into the later steam era. It is regarded as the only surviving engine of this type and is kept in its working condition rather than restored. The nomination treats it as a rare survival from the railroad's steam developmental period, when the system moved from steam to diesel by 1940.","period_of_significance":"1905","architect_builder":"Baldwin Locomotive Works, Philadelphia","architectural_style":null,"criteria":[],"status_note":"Presently in work-a-day condition, housed on track at Strasburg.","vacant_flag":null,"machine_generated":true,"model":"claude-haiku-5-5","prompt_version":"v1.1-2026-10-29","generated_at":"2026-10-29 17:11:32.464936-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/lz/electronic-records/rg-079/NPS_PA/79002263.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/79002263/f1c6e4616d-800.webp","url_1600":"https://nationalhistoricalregister.com/media/79002263/f1c6e4616d-1600.webp","licence":"CC BY-SA 4.0","author":"O484","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Pennsylvania_Railroad_2-8-0_2846.JPG\" rel=\"noopener\">O484</a>, <a href=\"https://creativecommons.org/licenses/by-sa/4.0\" rel=\"license noopener\">CC BY-SA 4.0</a>, via Wikimedia Commons","source_page":"https://commons.wikimedia.org/wiki/File:Pennsylvania_Railroad_2-8-0_2846.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/71993179","wikipedia":null,"wikidata":"https://www.wikidata.org/wiki/Q20822041"},"indexable":true,"url":"https://nationalhistoricalregister.com/pennsylvania/lancaster-county/consolidation-freight-locomotive-no-2846-79002263/"}
