I have a WBB O27 B&O Hudson pulling a 4-pack of WBB O27 streamlined passenger cars. All blue, nice looking train, but it's a short train. WBB did not make any add-ons for this 4-pack to my knowledge, so I'm looking to add one piece to it.
I don't mind the idea of a mixed train with a freight car, but was thinking an REA car would be more appropriate. The problem is that they're green and don't look good with this all blue train.
I know it's my layout and I can run what I want, but running "the right things" provides some educational topics for guests.
Any suggestions on a blue, gray, silver, or complementary-colored car that would look good? I was thinking maybe something like the red, white, and blue US Mail car that Lionel sold with the O27 Santa Fe streamliners.
Thanks.
