Paul, Yes my favorite railroad, Western Maryland had sharp graphics on the steam locomotives, whether the round herald or the fireball. While I would probably prefer something a bit more colorful on diesels, I do not like the late WM era circus scheme. So, the black with the Fireball will have to do. The B&O had a nice two tone paint scheme, but all the diesels I ever saw before Chessie were dark Navy blue.
It doesn't matter what you said you were going to do next, you found the right thing to do for this given day. The building is looking good!
