Hello Claudius,

Thank you for your contribution in Israel.

I wonder in what aspect is the Carmelit more a funicular than a subway, as it was previously tagged?

According to 
https://wiki.openstreetmap.org/wiki/Tag:route=funicular
a funicular is "A train that operates on a steep gradient by getting pulled by a cable".

IMO, a subway is different than a train and therefore the Carmelit cannot be a funicular.

Best regards,
Zeev
