April 2025 — Boston's MBTA Park Street Red Line train station.

April 2025 — Inside Park Street station, one of the oldest active subway stations in the United States. Opened in 1897 as part of the Tremont Street Subway, the station has long served as a central transfer point beneath Boston Common. The tiled corridors and low ceilings reflect early subway construction techniques, with later renovations layering modern lighting, signage, and safety systems onto the original structure. Directional signage for the Ashmont and Braintree branches marks this passage as part of the MBTA Red Line, which continues to use Park Street as a key junction between downtown Boston and the city’s southern neighborhoods.
