I have 2 LSOL tank cars (with different numbers), An Aristo 4th East Coast show boxcar I haven’t upgraded to my railroad’s standards yet, a Kalamazoo anniversary boxcar, the GR anniversary boxcar, and an MDC anniversary caboose. So I guess a red white and blue, 1776-1976 diesel could work. I know that someone, probably the Shawmutt Shops, made an dismal like that.
I will have to consider my options, and think about it for another year or so.
