11th Infantry Regiment is BTS Sukhumvit Line station N16 on Phahonyothin Road in Bang Khen, north of Bang Bua and south of Wat Phra Sri Mahathat. OSM and official BTS route and timetable material confirm it as an operational Green Line station. Commons and transit references place the station in front of the Royal Thai Army's 11th Infantry Regiment headquarters, opened with the northern extension in June 2020.

The catchment is institutional and commuter-led, with a large military compound shaping the station identity. Recognized anchors include the 11th Infantry Regiment entrance, Phahonyothin Road, Bang Bua and Wat Phra Sri Mahathat stations, the nearby Bang Bua/Sripatum University education zone, Anusawari and Bang Khen residential areas, bus corridors and pedestrian links. Commons provides licensed station, platform and regiment-entrance images, useful for representing the road and access environment.

For real estate, this is a practical north Bangkok Green Line station, not a luxury or nightlife node. Nearby condos and apartments can suit public-sector workers, university users, local office staff, military-related households and commuters heading to Kasetsart, Chatuchak, Mo Chit, Lat Phrao and central Sukhumvit. Check actual walkability, road noise, restricted-access edges near the regiment, availability of daily retail, parking, flood/drainage resilience, safety perception at night and competition from older apartments in Bang Khen.
