Livery detail: in pre 1980s times, NIR painted the NCC crane standard maroon. The GNR one at least had been painted red by the UTA. Yellow painted PW and maintenance equipment was unknown, apart from a few Cavan & Leitrim ballast wagons many moons earlier!
Prior to UTA, breakdown cranes tended to be quite dark grey or black, not only with the earlier UTA and predecessors, but GNR and CIE as well. At least one CIE one was lighter (wagon) grey in the 60s / 70s.
The NCC one at Downpatrick ended its days with the original (upright and gold-lined) NIR monogram. The GNR one at Whitehead retained its UTA cost of arms (not the red-hand-roundel) on its arrival at Whitehead in the 70s.
