OMTArchy - NYC Subway MTA
Live NYC subway arrivals for any station, straight from the MTA's GTFS-realtime feeds — no API key needed. Shows next arrivals in the bar and a full detail popup with whole-station multi-line tracking, search or browse by line, service alerts, a trip planner for direct and one-transfer routes, per-train stop-by-stop detail, and a “you are here” context strip for unfamiliar directions.
