Open Data Desk

Open data, map sources and delay logic

This page summarizes the public and derived datasets used by the rail twin. The layout is optimized for mobile reading and quick scanning.

Data layers

Base maps

OpenStreetMap is used for base geography. CARTO tiles power the standard and dark map views, while Esri World Imagery powers satellite mode.

Timetable data

Passenger timetable structure, stop order and station calling patterns are aligned with publicly available rail schedule information.

Thailand open data

Station names, rail locations and supporting geography are assembled from Thai public datasets and openly available geographic sources.

Delay deviations

Delay and early-running indicators are derived by comparing live train movement against the published timetable and expected stop timing.

Current map sources

Standard map

OpenStreetMap contributors + CARTO Voyager tiles

Night map

OpenStreetMap contributors + CARTO Dark Matter tiles

Satellite map

Esri World Imagery

Notes

  • Map attributions on the main map update automatically when the user changes theme.
  • Some operational fields are inferred from the latest movement frame when no direct public timestamp is available.
  • Coverage may vary by route, train type and station depending on source completeness.
  • If you have questions about data sources, delay logic, would like to suggest improvements or you believe your data has been used and you would like to be credited, please submit a change in the repository at https://github.com/andreybotkin/railtwin; the updated data will appear on this site in the next release.
