Don,
Any idea what era that was introduced ? I became an ex GE in December 94, no doubt news gratefully received by many of the operating crews. I have no memory of the black "ice indicator" during my time as a GE. My last trip with XV212 was on 26 Oct 94, a Banner A, and the black indicator was not there, in fact I'm pretty sure that 212 was finished in what some described as "lizard" but others as "wraparound". I suspect that the grey paint scheme, and ice indicators were nearer to 2000, and after I had left the mob, let alone GEing. Nice to see someone thought about the consequences of changing the paint scheme though.
