    This isn’t nearly that dumb, because the train isn’t actually riding directly on top of the solar cells.

      But still, what is the point of this? What problem does this solve? It’s not like solar power deployment is bottlenecked by a lack of space to put the panels.

      This just makes it more expensive and more difficult to maintain for no reason.

        Honestly if they’re using the power lines for the train and a cleaning attachment on the train I can see it.

      It’s close though, random shit gets dragged, kicked, dropped, etc all the time by trains.

      A chain , cable, or wire comes loose on a car and goodbye panels and like all of them …

        They could pair that with sensors / cameras for hanging things. These are already being produced and installed on tracks.

        If a chain, cable, or wire comes loose on a car then the panels are the least of anyone’s worries. Also expect emergency brakes to kick in automatically. This is a train, not a bicycle.

        I don’t why they don’t overhang them on frames. It’d cost more upfront, but hell alot cheaper than replacing the broken panels all the time.
