It is also known as the Concord Junction Depot.","why_significant":"The depot is significant for its role in the area's transportation history, linking an agricultural area to a national rail network and contributing to the growth and industrialization of West Concord. It is also a notable, largely intact example of a Queen Anne style railroad station. It is the only intact railroad-related building left on its original site in West Concord.","narrative":"Union Station is a small railroad depot at 20 Commonwealth Avenue in West Concord, Massachusetts, erected in 1893 where the Fitchburg Railroad met the Lowell and Framingham line of the Old Colony system. Its one-story, L-shaped wood frame sits under a broad slate hipped roof with deep eaves supported by braced posts. Originally the waiting room, baggage room and freight office were separate sections beneath one roof; the freight office was later demolished. Details include a round bay for the station master, eyelid dormers, leaded stained glass transoms, and decorative copper roof trim. The station was listed for its place in local transportation history and its Queen Anne design. The junction brought market gardening to local farms, supported nearby factories, and carried as many as 125 trains a day around 1900. Passenger service declined through the twentieth century. The building is the only intact railroad-related structure left in West Concord, and it was vacant when nominated.","period_of_significance":"1893-1938","architect_builder":null,"architectural_style":"Queen Anne","criteria":["A","C"],"status_note":"Used as a restaurant in recent years, but vacant at the time of nomination, with plans for purchase by the Town of Concord and eventual restoration.","vacant_flag":true,"machine_generated":true,"model":"claude-sonnet-5-5","prompt_version":"v1.0-2026-10-29","generated_at":"2026-10-29 02:13:01.439432-05","source_pdf":"https://s3.amazonaws.com/NARAprodstorage/opastorage/live/80/7961/63796180/content/electronic-records/rg-079/NPS_MA/89000143.pdf"},"photo":{"url_800":"https://nationalhistoricalregister.com/media/89000143/3d827d059c-800.webp","url_1600":"https://nationalhistoricalregister.com/media/89000143/3d827d059c-1600.webp","licence":"CC BY-SA 3.0","author":"Pi.1415926535","credit_html":"<a href=\"https://commons.wikimedia.org/wiki/File:Outbound_train_at_West_Concord_station,_May_2017.JPG\" rel=\"noopener\">Pi.1415926535</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:Outbound_train_at_West_Concord_station,_May_2017.JPG"},"district":null,"sources":{"nps_snapshot_date":"2026-05-22","nara_catalog":"https://catalog.archives.gov/id/63796180","wikipedia":"https://en.wikipedia.org/wiki/West_Concord_station","wikidata":"https://www.wikidata.org/wiki/Q7984863"},"indexable":true,"url":"https://nationalhistoricalregister.com/massachusetts/middlesex-county/union-station-89000143/"}
