Yep. Never polish a surface you need to stand on; it will bring you crashing down. Plus - unless you're one of those who spend your life watching trains from bridges - you're not going to see it anyway
Too true. My very first task as a cleaner was scraping the build up of slippery muck, sand and whatever off the full length of an Austerity (2-8-0) running plate. All very health and safety conscious long before the phrase was coiled, yet out on the road I was expected to bring coal down from the top of the tender and duck when the driver blew the whistle! What we were expected to do 59 years ago must be no less amazing to today's young generation than the stories the men told us about life when they were young.Yep. Never polish a surface you need to stand on; it will bring you crashing down.
