Back at work now after the Beer Festival and attention turns to the cabs once more. The hardboard inner roof is a silly idea - it burns well and provides no sound insulating quality at all. This was OK in the 1960s but it's not really fit for purpose now. We will replace it with perforated aluminium and a foam insulation as is commonly used on modern locos and some life-extension locos of a similar generation to this. The MCB arrangement is for the lighting circuits and is excellent at catching the top of your head, they will be moved to somewhere more convenient when the cabs are rebuilt. the switch panel will also go, to be replaced by one more accurate (like on the early Class 40s) for a Baby Deltic.
