Design of a network map for the Intercity Train services operated by the SNCB/NMBS in Belgium.
I could not find a complete map for this purpose; the SNCB doesn't seem to provide any official map showing the actual lines. The information is sourced from the official SNCB website.
Note that in the Flemish-Speaking parts, names are in Flemish, and in Wallonia, in French.
This is one of my first projects, I am a beginner in this domain.
Through the whole map, lines following the same route are displayed with the same colour, as long as possible; light blue for the path Halle-Brussels, light green for Antwerp-Brussels...
