Mike and all,
We were talking about this very thing at the club a few weeks ago. I was told that Freight Engines got the Green Bolier Jacket while passenger Engines got black.
This would make sense in the 474 case because as Mike pointed out the 474 was the only K-28 NOT set up for passenger service.
This all came about because the Green on my 478 does not match the Scale Coat Green NO.45 must of us use for the San Juan colors. Someone pointed out to me that it shouldn't match Green was for Frieght.
Now we just need someone to confrim that.
