It's more like. "This is significantly more complicated and expensive than the obvious simple solution we already have". The same money that is being spent on this project could instead be spent installing much more solar on rooftops or solar farms. In an ideal world we would try both but in this world we have limited budgets and time.

There are interesting aspects to the project like the idea of the train being able to clean the panels as it goes over them, or having a pre-made track for easier install and maintenance, but these seem quite minor when you consider the number of obstacles (increased mechanical strain, possibility of damage, non-optimal angle, hard to schedule maintenance around train times, maintenance is more dangerous, all the panels are placed linearly so you need extra cable routing, large efficiency losses when you're trying to transport low voltage electricity from remote areas).
