Thanks Peter, I think you misunderstood me. I'm talking about when you're running on ambers and looking out for a faint hint of yellow or red in the distance. I'm well versed on working practice, I may have joined later in 1989 but the training was still very thorough. Like your good self, I've been lucky enough to be in the cab of many long-extinct classes of units and locos. I've driven under instruction, my career took me towards safety and investigating crashes though.
