In terms of details and correctness, I'd give the Atlas Chessie SD40 an "A" and the Lionel an "A-". Overall I'd rate both engines an "A". The Atlas model has slightly better detail but the LEGACY sounds and lighting make up the difference in that category.
Thanks to Gunrunner John and the late Boxcar Bill all 3 of my Atlas SD40's run and sound amazing with their ERR Cruise Commander and Railsounds Commander upgrades.
Here is a picture of all 3...
Catnap! I think I'm in heaven!!
