From the readme:
Two Western Fruit Express green cars, derived from photos, with single numbers.
Three CN white cars, including a billboard car (single number), a car with the CN reporting mark, and a car with a BCOL reporting mark (these autonumber).
A Great Northern 'Tater Frater' in yellow - auto numbers.
A Santa Fe SFRC orange with the large logo - auto numbers.
A BNSF 'icicle' car (a fantasy paint, as this was only applied to the Plate F overheight cars) - auto numbers.
Many thanks to Larry for pulling out his hair and making sure the auto numbering schemes worked on these cars.
More to come!
