Creates GTFS file for the biggest Polish railway operator (by passenger numbers), PolRegio.

Schedule data comes from their ticketing system API. It falls under Article 5.1 of the public sector data re-use act. The agency has not expressed any requirements as described by Article 11 of that law (as of 2021-07-07), thus, following Article 11.4, this data is available without any license-like requirements.

Stop positions are downloaded from my other project, PLRailMap, which is also released into the public domain (under CC0-1.0 license).

This means that the produced GTFS file can also be considered as if it was released into the public domain, or under the CC0-1.0 license.

PolRegioGTFS is written in TypeScript for the Deno runtime. Additionally, in order to create a zip file, Info-Zip is required - on most Linux distribution the required package is named zip.

After installing the following requirements run ./polregiogtfs.sh - which sets up required permissions for the Deno runtime and simply calls PolRegioGTFS.main().

As it is necessary to make a lot of calls to the API in order to get all of the schedules it might take a dozen or so minutes for the script to complete.

PolRegioGTFS is provided under the MIT license, included in the LICENSE file.
