One of our Club members has one of the Williams 1218 Models, and installed the new MTH 3.0, installed 2 large speakers in the tender, a new smoke unit with fan!
This is to date, the loudest Model Railroad Engine that I've ever heard anywhere, anytime. He told me that this was the newest issue of the PS 3.0 series. What that means as to the latest edition of PS 3.0, I'm assuming there was a 1st edition, but what ever!
I have one of the MTH PS1 C&O H-8's, and planning on getting him to install the PS 3.0, and new smoker, and sound system, as he did on his, Big articulated engine. When you have a big articulated locomotive, with an exceptional sound system, it makes you for get about the detailing items that's missing, as would be on a 3rd Rail Model, or something of the equivalent!
Oh Yeah D500, you are correct, as I forgot about my Crown Masterpiece J611 that I have. Just got little less than 2 bills in that one....................Brandy!
