UK Public Transport Stops by Area: NaPTAN Stop Counts and Localities (DfT)

dftnaptan/area-stop-summary

Summarises the Department for Transport's NaPTAN register of public transport stops for one ATCO area code (the first three digits of a stop code, for example 490 for London or 920 for airports): the total and active stop counts, the count of each stop type (bus, rail, tram, ferry, airport), the 25 localities with the most stops and the first 50 stops in code order with name, street, locality and coordinates. It cannot search by stop name or place. An unknown area code is an error. Open Government Licence v3.0 data, served by Eden Engine; not an official Department for Transport product.
