I was looking around and found a Lionel 6-28044 Hudson for sale. I don't know much about it, but it appears to be a semi-scale Hudson (also referred to as a "baby" Hudson - 21" long) with a can motor and signal sounds and command upgradeable. It looks like it was part of the 2000 6-21956 New York Central Freight set. Interestingly, Lionel had a similar set the same year with the only difference being conventional railsounds, with the set number being 6-21988 and the Hudson 6-28065.
Is anyone familiar with these Hudson locomotives or similar vintage as far as looks, operation, problems, etc.?
