[HM181]

The coldest one I've bin on was a class 31 used on the Leeds Electrification Trains in the winter of 1993/4.
The windows and doors fitted where they touched, and the windows slid down in you did not sprag them with some card board. If you were in the back cab, you got gassed, and the hand brake skinned your fingers when applying this brake.
Peaks were nice warm locos even going at a fast speed, with simple seats which were very sleepable.
Class 56's heater was either on or off, it worked well in summer and blew out cold air in the winter.
DMU cabs were ice boxes.
The best cab I've been in was the one we came back from Immingham on one Friday night for a 4 hour shift. Always good to get back home ASP.
One thing with BR was they issued you with a thick black overcoat, which could fend of a howitzer shell, wear that on any loco with the wollen scarfe yer mam knitted for your Christmas Box, and a German Army Coldweather hat it was as warm as toast.
