you must mean "Green & White Paintscheme"?
a "consist" means a multiple unit diesel lashup.
yes..they all wore B&N Green & White..
some were built for Great Northern, and were then repainted in B&N green..
the rest were built new as BN units, and arrived new in B&N green..
actually..I dont think they ever wore anything BUT green & white while with B&N!
(except maybe before the GN units got repainted..but they all only wore the one B&N scheme)
(and they were F45's..not F40's)
