This is another borderline case here.

Indeed, there is one PDF somewhere where they put that name, but just like any source it is difficult to ascertain whether the name they wrote can be trusted.

Having secondary sources would help but I couldn’t find any; only self-referenced sources, namely the wikidata entry you created or websites linking to OSM data.

Maybe we should leave a fixme tag on the way, to mention there is some uncertainty about the real name, so that we can close the note.

Also, a friend who is knowledgeable about rail transport told me there was never any train or tram under the current railway line here → railway=abandoned can be removed.
