Solar panels on rail tracks are an interesting experiment, but mind that they complicated maintenance work on tracks and require quite some maintenance themselves. (Think about oil and other dirt dropping from trains; stones and small tree branches etc being thrown around with the force of the train...) But even if they are useable and beneficial: That's not an argument not to use other available space as well.
