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).
Jeez, solar freaking railways.
Railways are dirty, brake dust, oil and lube leaking, human waste (from a car toilet if there is no tank).
There are “defect detectors” on railways to warn engineers when their train has a chain, air hose, etc dangling and dragging along the ground - which is a potential for accidents of many varieties.
I guess now you can replace that with trains that automatically stop when the Katamari of dislodged solar panels eventually builds enough mass to force a car off the rails.
They make a better roof over the tracks that the train passes under than being on the ground. They could even be tilted to better face the sun.
This is Switzerland, not India. Also, it’s a test. It’s designed to find out exactly how serious those problems are and if they prevent the system from being effective.
Is this the same bunch of people that wanted to make solar roads/bike lanes too?
I could see a solar road working with some kind of passive heating medium circulated underneath but even then, the maintenance on that would be a nightmare. We can barely maintain all the roads we have already, and that’s just goopy rocks and grading.
Next test: solar panels on the bottom of the ocean.

Cause those things are similar!!
Putting solar panels between rails is as stupid as solar roadways. There is nothing to be gained and just lots of hurdles to overcome to make it (almost) as good as a normal solar panel on a roof or on a stick or on a wall.
Tell me, why on earth would you put solar panels between rails?
Edit: lot of anger here, but no answers why the panels should go between the rails, shaken daily by heavy trains. You invested in it or what?
were just trying to find some efficiency in the space wasted by rail not-in-use. thats a lot of land. im not saying its possible, but i dont think thought experiments about these kinds of things is a bad idea
That’s like 0.00000001% of land.
There is so much unused land, why bother trains and their schedules with a maintenance nightmare between their rails?
It is just a stupid idea with no upside except the oily greasy dirty solar panels up-side that can’t get cleaned because, … wait for it …, there are Trains running over it!
I can’t fathom how such a stupid idea got more that 1 meter away from the bar counter.
Because none of that unused land is set up to allow a machine to easily roll over it and automatically place/replace/clean the panels. Putting panels between the tracks means you get that for free, as the tracks are there anyway, and are already have electrical infrastructure all along their length.
The point of the experiment is to see if those benefits end up outweighing the presumably higher chance of panels getting damaged. In the worst case it ends up not being worth while and there isn’t a huge loss, in the best case we end up being able to add a bunch of additional solar capacity without having to build much new infrastructure or cover any previously unused land.
And it would be trivially easy to have a train run over the tracks to clean the panels, there are already trains which use compressed air/sandblasters/lasers to remove leaves and stuff from the rails. Just add a few more compressed air nozzles in between and boom, all your panels are now clean.
I agree, there’s so much land elsewhere. Even just beside the tracks would be better than between the tracks
That could actualy have real world benefits, like when there are few trains, a special small train could go by and let maintenance people off/on there for example.
ha, ok. youll be ok. its alright. everything will be just fine.
why dont you have some nice warm milk and this cookie. youll feel right as rain.
Everything will be fine, except this extraordinarily stupid idea.
Did you invest in it or something? I mean you have no answers just other than “here take a cookie” lol
Surely the maintenance of such problems would be very easy though, given it’s already on rails you could run a carriage with washing machinery underneath to clean these occasionally. Interested to see how serious the deterioration over time is due to the grime.
