I bought it and most definitely will run it when I get it back from Lionel (sent there for repairs).
We go to the Museum of Transportation once or twice a year, and always take a long look at the Big Boy. As was stated above, it is deteriorating. When I moved to the St. Louis area in 1985, the Big Boy was in really bad shape. A few years later, it was 'refurbished' (looks-wise) and was an excellent display. But the weather has slowly but surely rendering it in poor condition again.
