You will probably see the Class A with Legacy sooner or later. They have the tooling, but it's not like a J3 Hudson or a Challenger that you can rerun every couple of years and expect it to sell.
Hopefully if they run it again with Legacy they will get the paint and the horn/whistle right. It's a very nice engine and the clamshell doors on the nose are kind of a cool feature to show off. Mine is the first Lionel engine I ever owned that smoked decently.
