The route
What the journey actually looks like
Direct or connecting, how far the route really runs, and what happens when a connection is missed.
- How far it really runs
- The route covers 797 km against 774 km in a straight line, a detour of 3 percent. Track and road geometry account for the difference.
- First and last departure
- The first service of the day leaves Brussels at 06:12 and the last at 20:46, across 24 departures. The return direction keeps its own timetable, so the times back are not these times reversed.

Where these numbers come from
Observed service A carrier record shows this named operator serving this named pair, and we carry that through unchanged.
Schedules, seat counts and fares are generated by our own model until the supplier contracts are signed. Places, coordinates, operators, which operator serves which pair, and every distance are real. We would rather say that on every page than let a modeled number pass for a filed one.
