Follow-up with details, in case it helps. (Note at the station: note/5556256)

19 steps/escalators have one end within 3 m of a platform at a matching level, but they share no node with it. This list comes from the data only (2D distance and level tags). We did not check it on site.

Platform 6 (level 1, way/1199457846):
- way/1199520086 (steps, level 0;1): node/11125489668 is 1.3 m from the platform

Platform 11;12 (level -1, way/1199457851):
- way/1199520105 (escalator, level -1;0): node/11125545314, 1.4 m

- way/1199520116 (escalator, level -1;0): node/13480358112, 2.4 m

Platform 21;22 (level -2, way/469218448):
- way/1199520134 (steps, level -2;-1.5): node/11125545376, 2.0 m

- way/1199520147 (steps, level -2;-1.5): node/11125545406, 2.9 m

Platform 23 (level -2, way/469218447):
- way/1199520128 (steps, level -2;-1.5): node/11125545362, 0.3 m

- way/1199520144 (escalator, level -2;-1.5): node/11125545397, 1.9 m
- way/1199520146 (steps, level -2;-1.5): node/11125545404, 2.6 m

Platform 24 (level -2, way/508249250):
- way/1199520129 (escalator, level -2;-1.5): node/11125545364, 0.3 m

Note: the other end of these steps/escalators is not connected either. They arrive in the hall, which has no walkable way. So connecting the platforms alone does not fix routing: a path through the hall is also needed.

Hello Waaslander, thank you for the detailed indoor mapping of Antwerpen-Centraal. Most of the steps and escalators from this changeset share no node with the platforms or the halls (e.g. way/1199520097). Pedestrian routers then cannot find a path through the station: they walk 879 m around it to reach platform 24. Can you connect them, or tell us if someone else should do it? I added a note with details at the station. Thank you!
