Additional information

[Please modify this part]

SNCB deprecated their HAFAS endpoint and switched to an Azure-hosted HAFAS OpenAPI endpoint with custom arrival/departure boards.

[schildbach]

What's "HAFAS OpenAPI"? Do you have some link?

[Muspah]

There's not much public documentation, especially not with the more recent version that SNCB runs.

The only public implementation for SNCB that I'm aware of is https://github.com/irail/irail

I'm mainly working on creating NeTEx/SIRI, I don't know all the implementation details around the API endpoints.

[Muspah]

An older version of the API spec can be found in: https://projects.shift2rail.org/download.aspx?id=4f1ad68b-0e62-4183-98ae-7232a5c519bd

SNCB only offers JSON endpoints and only specific endpoints are available. TrainSearch is missing for example, looking up a specific journey requires multiple calls and/or caching JourneyRef's.

[schildbach]

Just for reference, the highest version the endpoint knows about is 1.51 – yields CLIENTVERSION. Any higher version yields VERSION Invalid version.

I decided to remove SncbProvider, as there so no chance it will ever work again.
