You could get the blue and red on Mark 1s as well. The story goes there was this derailment up Ebbw Vale steel works. Some 100ton bogie oil tanks broke loose and went out of the end of the siding. They were loaded with 3500’ oil which was being warmed up for discharge, and one of the pipes underneath got knocked off, and all the b***** oil ran out and set. When it’s cold it’s thicker than tar, very black and very sticky. There was a blizzard going on, so it got covered in snow. The breakdown gang got the tanks back on the line, by which time oilskins, boots, were completely f*****, and the inside of the two coaches (old bow ends) ruined.
so we got two mark ones in the wagon shop, strip out, mess, riding, tool, and packing store conversion. No drawings, you just wing it. To finish off we just painted out the grey upper panels, and did them red, as an arty hand book “the corporate image of BR” said that was the scheme for service vehicles. Once they were seen out and about at Canton the people at Derby Tech centre complained we had taken their livery, and we should have done them plain red, but red and blue was how they stayed.
