I saw this engine on eBay, so I bought it, thinking it might look nice on a bookshelf.
This is my first "modern" Lionel, and as I've mentioned elsewhere, it's terrific.
Although running it wasn't my initial intention, I then purchased a batch of "FasTrack", so I could see it in action. It (the track) too is very nice.
I have a small fleet of 2-rail, and I thought I'd have to convert some of the freight cars to run with this loco; imagine my surprise (and delight) when I discovered that, for whatever reason, the existing 2-rail wheels are compatible with Fastrack. Must be in the design of the rails themselves...plus, the "claw"-type coupler on the tender I'm using (#2466) does indeed mate with the KDs, something I've read before, but never actually tried.
This just keeps getting better and better!
Anyway, I thought I'd share this happy story with you all...as I mentioned before, the whole "3 Rail Scale/ Hi Rail" thing was lost on me, but given the vast amount and selection of motive power (and rolling stock) that's available in this field, it now makes sense!
