First of all, welcome (a bit late) Don. Val, your comments reminded me of a night early in my membership of a club. I had shyly entered a model railroad club in my area. Shyly, because although I had many years of "modeling" behind me, I had always been a lone wolf type. This was late 70's or early 80's. Atlas had just come out with RS3's, and I brought one to the club this night. Two of the "veterans" started arguing (with each other, not me) about which model Diesel engine was in the prototype, and when it changed to a different engine. After about 5 minutes I was losing interest and thought it strange that they seemed to be getting aggitated. Another 10 minutes and I simply told them mine has a 12 volt motor and left them to find refuge in the company of others, who turned out to be Blake and Mark, also members of the Gauge. Mark was much more amusing, focusing on imitating the sound of the Diesels rather than caring which model it was. A poor mans sound system, if you will. I have no experience with the Atlas forum, landed here first and it is the best I've seen. Thanks to all.
