Solar surfaces could make sense if they prevent unwanted vegetation growth along the rail tracks. Sleeper surfaces would be too small for meaningful solar power production, but modules could be fixed to.
There could be some connection between solar modules, so that they can be lifted easily upon works at the track, and be put back easily. On the other hand, they would have to withstand aerodynamic forces from the trains. The modules would in any case show whether rail traffic is clean.
