I doubt the users of these lasers thought they were doing any damage. Most of these devices have the ability to turn them down. My guess is this is something which has gone unnoticed.

The fact that 9 coaches have been found in a casual walk around the Newell plant leads me to believe this is a common practice. Not including the past repairs of similar nature the factory has reported to me.

That is why I am asking the question in open forum. Saying it ain't so, doesn't make it so.
