So, how did the story end? )

We drove back. Some days later, the fire brigade cleared the tree.
This is one of their official duties in Belgium but of course no urgency could be invoked here. The tree might have been there for quite a long time and for a tourist tram they are not going to come urgently: these are tasks they have to do, but certainly not with urgency. This would be completely different should it be a public road or a regular tram line: the tree would be cleared immediately.

In May 2024 I found this equipment carried on the train, perhaps due to this very incident:
