Pretty much like every year, I did a nice clean-up of the layout, the tracks, and the train room. I cleaned the tracks with the rubber and ran the Roco cleaner afterwards.
You can clearly see the difference: clean on the right and not so clean on the left with cat hair ...
While cleaning the tracks, I have to be careful not damaging the ballast. Unrelated, but it just so happens that some of the ballast didn't hold well to the vacuum. I'm not sure if it wasn't glued properly or if it got damaged through the winter because of temperature differences and UV light ...
But, at least, trains are running again!!
