I enjoy seeing grassy tram tracks, but is there something even better we could grow between rails?

Skinny solar panels, feeding back into the grid?
Unlike solar roadways, this actually makes sense. Lots of tram systems also use DC, eliminating the need for inverters. And yes, panels are so cheap it's not too bad that they're horizontal; vandalism is a greater issue.
I saw a post recently about a proof-of-concept solar railway in Switzerland
