@fj you're right that this is a "no brainer", in the sense that this idea only makes sense to someone who isn't thinking.

Now you can't inspect the line. The risk of derailment from loose, improperly fitted, or damaged panels poses a danger to on-train staff and the traveling public. An incident with loose RRAP panels in the UK recently comes to mind. Track staff are more likely to slip and fall or to twist their ankle.

Any risk is unacceptable considering the panels have no inherent need to be there.
