Data sources & attribution
TransCAPI is built entirely on open data. This page lists every source, the licence it comes under, what it powers in the API, and the attribution you need to show if you display TransCAPI data in your own product.
Coverage
TransCAPI covers Great Britain (England, Scotland and Wales), since 18 October 2026 the whole island of Ireland, the Netherlands and, since 19 October, Belgium. None of these is in NaPTAN, BODS or the Network Rail timetable, so:
- Northern Ireland comes from Translink's own open data: Metro, Glider, Ulsterbus, Goldline, Foyle Metro and NI Railways. Scheduled times only.
- The Republic of Ireland comes from the National Transport Authority: Dublin Bus, Bus Éireann, Go-Ahead Ireland, Luas, Irish Rail (including DART and the Enterprise to Belfast) and about a hundred private operators, with Ireland's own stop and place registers. Irish Rail trains have live expected times from Irish Rail; buses in the Republic have live times, cancellations and positions from the NTA's GTFS-Realtime feed. Luas trams have live expected times from TII's Luas Forecasting API. Northern Ireland has no live data.
- The Netherlands comes from OVapi's national feed, built
from the NDOV data: NS and the regional trains, every bus, tram and metro
operator (GVB, RET, HTM, Arriva, Connexxion, Qbuzz, Keolis and more) and the
ferries, with live expected times and cancellations for all of them, and
their service alerts in
/v1/disruptions.json. Times are Dutch local time (Europe/Amsterdam). Stations can be shown whole, every platform on one board. There are no Dutch fares. - Belgium comes from its four operators' own timetables,
through the Belgian Mobility Company's open data portal: SNCB/NMBS trains,
De Lijn (Flanders), STIB-MIVB (Brussels) and TEC (Wallonia), buses, trams
and metros. Stops are placed in their municipality, and stations take the
name on their signs (Antwerpen-Centraal, Liège-Guillemins, Bruxelles-Midi /
Brussel-Zuid). SNCB trains, De Lijn and TEC have live expected times and
cancellations, and TEC buses live positions; Brussels' STIB has expected
times from its own waiting times for the next two of each line at each
stop. SNCB, De Lijn and TEC service alerts are in
/v1/disruptions.json. Trains between Belgium and the Netherlands come from the Dutch feed. Times are Belgian local time (Europe/Brussels), and there are no Belgian fares.
| Area | Coverage |
|---|---|
| Stops, stations and places | Great Britain and Ireland. Northern Ireland's towns come from the town names on its stops; the Republic's from its own place register |
| Bus departures, arrivals, routes and services | Great Britain, refreshed daily from the national BODS export. Ireland from Translink's and the NTA's timetables, refreshed daily, including NI Railways, Irish Rail, DART and Luas, each with its own mode |
| Live Irish trains | Irish Rail, DART and Enterprise trains: expected times from Irish Rail on departure and arrival boards and journey legs, within about 90 minutes of now |
| Live Luas | Transport Infrastructure Ireland's forecasts for every stop: expected times on departure and arrival boards (source: "luas_forecasts"), and the line's status in messages |
| Live buses in the Republic of Ireland (not Luas) | The NTA's GTFS-Realtime feed, refreshed every minute: expected times and cancellations on departure and arrival boards and journey legs (source: "nta_gtfsr"), and vehicle positions in /v1/bus/vehicles.json |
| The Netherlands | Stops and towns, every operator's timetable (trains, buses, trams, metros, ferries) refreshed daily, live expected times and cancellations on boards and journey legs (source: "ovapi_gtfsr"), vehicle positions in /v1/bus/vehicles.json, and journey planning. Dutch trains are in the bus endpoints with mode: "rail", not /v1/rail |
| Belgium | Stops and municipalities, the timetables of SNCB, De Lijn, STIB and TEC (trains, buses, trams, metros) refreshed daily, and journey planning, planned together with the Netherlands. Live expected times and cancellations for SNCB, De Lijn and TEC on boards and journey legs (source: "bmc_gtfsr"), TEC vehicle positions in /v1/bus/vehicles.json; STIB is timetable only. Belgian trains are in the bus endpoints with mode: "rail", not /v1/rail |
| Live bus positions | Operators reporting to BODS: England, some of Wales, little of Scotland |
| Live bus delays and expected times | Wherever operators report positions to BODS (most of England, some of Wales, little of Scotland), where TransCAPI tracks buses against the timetable |
| Rail departures and arrivals | Great Britain, with live expected times, platforms, cancellations and delay reasons from Darwin within two hours of now |
| Rail services (one train) | Great Britain, with live expected and actual times at each call for trains running today |

| Rail fares | Great Britain: every fare for one adult, with railcard prices, reloaded nightly. No seat availability for Advance fares |
| Journey planning | Great Britain, the island of Ireland, and the Netherlands with Belgium, as separate areas |
| Bus punctuality | From tracked buses: northern England and West Sussex since 4 August 2026, the rest of Great Britain since 30 September 2026 |
| Reachable areas and travel times | Great Britain, Ireland, the Netherlands and Belgium, every timetabled mode, today and tomorrow |
| Airports | The 50 airports in Great Britain with scheduled flights, and the public transport serving them. No flight data |
