I have the 1990 700E. I picked it up on EBay a few years ago. It replaced a Williams scale Hudson which I bought new and was a terrible runner.
Normally Williams engines are great but not the one I had. I sold it and got the Lionel 700E "Made in the USA" version.
It runs great and I have gradually collected the matching semi-scale freight cars to go with it.
The Vision Hudson would be nice to have but we also own a Dreyfuss Hudson so two is enough! Got to be a bit selective as we don't have unlimited space
