You’ve complicated maintenance of both the railway and the solar. If you used the space literally next to it in the picture, both would be simplified and have current real world cost and deployments. This is just an investor scam so they can take a bunch of money, and say it was all for this test, that will turn out to be worse and more expensive than anything else.
Then they will try to sucker another city into funding a new test.
Or made it easier, since you could do maintenance on the panels with some rail cart directly. I see how solar roadways may not have been convenient, but with rail it’s not as dumb. Placing the panels on the side also means more land use, and not every place in the world is spacious, especially Switzerland
Also, you usually crush and shred the materials in solar panels for recycling, so no one cares if replacing a panel means smashing it to quickly get it out between the tracks. Train tracks move far more than most people would expect, so the panels are already going to have a built-in buffer zone in which you can quickly and easily place a panel. As someone else said, something riding on the rails would likely be leveraged for installation.
Rails have a fairly consistent width when measured on a rough scale, as does the vehicle riding the rails have a fairly consistent center point. As long as the electrical leads are robust enough, and the contacts forgiving enough towards slop, the panels could be designed to just drop in. If curves are too difficult or expensive to accommodate, only install at the flats.
As with any program like this, as long as the overall energy output exceeds the cost of installation, then it’s totally a net positive, even at the lowest levels of efficiency. And if parts break, but you’re still netting positive, then little or no maintenance should be considered over the lifetime of each hardware deployment.
The key thing is ensuring that contracts with suppliers and workers are reasonable and benefit local communities. But that’s just about the biggest difficulty with any transaction these days, isn’t it?
Fair comment, though in real life the space near the tracks is either non-existent either uneven ground filled with rocks and plants, but as other pointed out it could be on roofs, parking lots, etc. Also, apparently the SNCF says they are specifically testing how much it complicates maintenance, so they are aware of this, but even then it’s less direct to test for that, and maybe built it in the future, than to built it in already adapted places.
I mean if it’s hardened against dragging defects, I don’t see why not

It appears dumb, until you think of automated deployment and maintainance, leveraging existing infrastructure.
