Nothing new in the tooling, however, (for those who think Lionel doesn't listen to some extent. Lionel blackened the running gear on this model.
The last F12e had a great whistle, IMO this one may top it, similar in tone but this is one of Lionels best efforts in the realistic quilling dept. The whistle is as real sounding as it gets. The first crack of the whistle is incredible as you can hear the steam begin to "crack a note".
Nice job Rudy!
