On the [chat](https://matrix.to/#/!SqvNXrBsvdGHYRyota:matrix.org/$17603452323692MDzkh:matrix.org?via=matrix.org&via=kde.org&via=matrix.domainepublic.net), people tended towards not treating this line differently than other pre-metro systems. I know this has been discussed before. Maybe we can discuss this on the forum for easier archiving, and perhaps update https://wiki.openstreetmap.org/wiki/WikiProject_Belgium/Conventions/Railways with current practices?
