Lionel did these correct scale B & O F-3s. (Pretty cool and unique feature: the front "115" engine number just below the headlight is illuminated.)
I know those are beautiful! Almost pulled the trigger on a set, but they are much older models with TMCC and only 4 rpm sound levels. If Lionel could just redo those exactly but with Legacy speed control and Legacy sounds, I would be one happy camper!
