The scale PE Berkshire was the highlight for me, such that Lionel delivered the model that looks and sounds like the one from the movie.
Personally, I experienced many defective trains and poor service in 2014, both from brand new trains from dealers and new-old stock items. While a bummer and pain in-the-neck to deal with, this really didn't hamper my enthusiasm for the hobby. If anything, it only reinforced what's best about the hobby, at least for me, that is, building and sharing the layout and running trains.
