Ye Gods, yer taste be in yer mouths, laddies. The best FA scheme on the LIRR was the first; platinum with a blue streak and a yellow pilot. Trouble was, they showed the exhaust spatter so terribly. I reported in Extra 2200S, way back then that LIRR FA's were unbelieveably filthy. I have an FA that is currently in NYC livery, but will get the repaint sometime this summer.
This also accentuates why we need a plastic C-420 in powered and dummy versions. Running HO Push-Pull trains is a dog otherwise.
