It might be a stretch since Lionel is of course doing their A class and they probably don't wanna detract from it as well as the fact they did them in Scale a few years back, but I would absolutely love to see a Lionchief J class.
If for some reason this is a repost, then I would also like to see some Lionchief versions of the 41 Army turbine switcher or any of it's repaints or snowplow variants. I know they have the tmcc versions of these but if we're all just throwing ideas here I figured this would be a cool one to suggest.
