You have a Williams Masterpiece Dreyfuss. They came out right after Lionel's Smithsonian Hudson. I have not seen the Lionel engine in person but from the pics they appear identical. Electronics differ though. Williams also made a Masterpiece unstreamlined J3a. These are both fine engines.

I have both the Smithsonian version and the later version made by Lionel again. They are pictured here on my layout.
AMCDave, what I can tell you about the Smithsonian model is that it is very, very impatient with curves anything less than a full O-72, and that it simply will not traverse Lionel O-72 switches, esp. not backing through, as I tried to have mine do um-teen irritating times.
Eventually, I observed that what was preventing the derailments was not the engine's wheels but the trucks on the tender. The trucks swivel only the slightest amount (a 1/2" [?] swing, left or right) due to the shrouding.
So, when I bought the newer, also-scale version, I made sure I moved the trucks back-n-forth. They moved far more. Thus, this engine (whose horn/whistle/bell feature is fabulous!) and its 10 car consist are my favorite on the layout, having not been off for a decade.
If yours is related to the Smithsonian model, I'm offering you my experience so you can be aware of those trucks if you get derailments and wonder why.
Both models at the station...
The non-Smithsonian scale Lionel version zipping through town...
