Greater Asia Reachability

An isochrone-based reachability tool for passenger rail across the continent — 4,382 stations and 5,031 services spanning 35 Asian countries. Users select an origin and a 1–48 hour budget to trace exactly how far Asia moves by train, while a disconnectivity layer overlays the missing links — the Korea Strait, the Java–Southeast Asia gap — that still keep the region from being a single rail world.
