Just finished an American Standard 6-3 Pullman kit that I did on ACL purple. I’ve never seen one done in O scale as I don’t think anyone has ever made the purple paint. Finally Tru-color came out with the paint. Yea for Tru-color! The yellow striping was painted on then masked for the purple. Then the purple was masked and the silver applied. The lettering is from 3 different Champ sets. The ACL on the letter board is from a Champ ACL passenger car set, the car name is from a Champ Pullman set & the small Pullman on the ends came from a NYC passenger car set. This one was a lot of fun to do and a challenge.
Below is a T-1 that I weathered. Don’t know who painted the model initially. I wanted that “in-service” look as well as some reddish tint (like GA clay) on the trucks and tender frame. Other colors used were two types of grime, sand, grimy black, rust and dirt.
