Eric,
Really enjoyed this review as I am a big Pennsy fan. I have the original TMCC M1a which has been upgraded to 4 chuffs and a GRJ super smoke board. In my opinion the sound board was one of the best Lionel ever put in a stream engine. Glad to see the new Legacy engine sounds as good or even better. On top of that a smoking whistle, maybe I will have to hunt one of these down.
Keep up the great work on the reviews.
