I don't see many 4-4-2 Atlantic types steam locos around, and even less orange-colored trains. This should fix both problems at the same time, and yes, it's build-able in this color in real life.
I'm thinking about making it Halloween or Harvest themed, with a literal skeleton crew (not too scary, mind you) and number 1031, after the date of Halloween. (Think along the lines of the 1950's-set Polar Express number 1225, with my train being called the Halloween Flyer straight from the 1890's.)
The Atlantic type 4-4-2 (4 leading, 4 driving, 2 trailing) was the top-of-the-line express train hauler in the middle 1890's to early 1910's. Some continued right up until the end of steam, with the Hiawatha's of the Milwaukee Road hitting 100 MPH speeds daily with this wheel arrangement.
The cab of the loco with four printed gauges and the firebox door.
The engine should have "1031" in printed tiles on it's cab and "BRS" on it's tender. I may change the tender at a future date to say something different, like "Halloween Flyer".
Three passenger cars in matching orange paint-scheme are pulled by the Atlantic-type steam locomotive, with the last one having red tail-end marker lights.
