so this topic made me really want to sign up for the forums. after being sent to IJ:ST several times last year and actually being part of the crew this year, believe me, those trains are hopeless. Every night we either wax or lime-away those trains, it doesn't matter how hard you scrub, the trains are still going to look just as dirty after one cycle as they did before we cleaned them. so we are putting the effort in to clean them, its just the water they use so nasty its pointless to attempt to clean them
