I agree with Tinplate.. Hope you find one, it does have perhaps the best sounding whistle of any of my RS engines. Not just my opinion, I have had many comments by club members and others about how great it sounds. It is a great puller, also. I have added approx. 20, or more, cars to the 4 boxcars that came with the set. Also, glad to have in my roster of Hudson type engines.
