I’m all for putting solar panels all over the place, but won’t these get dusty and oily and need loads of cleaning after trains pass over?
Also, costing €623,000 over three years sounds rather expensive for just 100m (although that roughly equates to 11KW).
Hopper cars lose coal and ore all the time
This is Switzerland, outside of a small number of corridors the majority of tracks see virtually nothing but passenger trains.
Trains with hoppers are not present on all railways though.
But these solar panels will be present on those with hoppers.
i’d be more worried about about smudgy stuff. they get dusty, then it rains and the panel is covered in a film of dirt. bird shit on solar panels is already plaguing home users
