Well looks like I have several choices. I like the fact that the bachman's are any easy switch...might go that way for now. Aristo's seem to operate nicely on my Sierra cars, could go that way too. In regards to the Kadee's what's a height guage & how does that work? Oh, and Brian nice tip on possible freebe's. Thanks for the help everyone,best wishes... Oz

I just purchased an Aristocraft Sierra passenger car set & hooked them to my Bachman 4-6-0 "Annie" and was surprised  that the couplers did not match up. Not only was there a differance in height,[bachman's are lower] but the locking mechanism was slightly different. It seems like they would not click together properly to stay coupled. I think the easiest fix would be to change the bachman coupler to match the aristo's. My question is what brand coupler should I use . I want to stay with the knuckle style coupler. I see some folks use Kadee couplers, is that the way to go? If so what style or number are they? Or any other suggestions, I'm a newbe so I apppeciate the help. Thanks Oz

Well sounds like I should be ok to interchange the rolling stock. As I said I'm just starting out so, my layout will not be that big to start. I plan to run the " Annie" & an Aristo Classic 2-8-0....but not at the same time. I'll probably go with track power to start, & battery power later. There will definitely be more ?s when I attempt that. So for now all I can do is wait out this Wisconsin winter....come on spring!!! Thanks again everybody, take care. Oz

Thanks everyone for the helpful tips. Wow what a great forum this is. Like I said,  I'm sure there will be more questions to come. Thanks again, Oz

Hi, I'm a first generation "baby boomer" & electronically challenged so bear with me please. I'm new to the G-scale hobby,& had a few questions about rolling stock. First, do Aristo & Bachman cars look ok hooked together ? Just wondering cause the scales are different. Also, can the top of the stock cars be removed on the Bachman cars to make a trailing battery car, easily I hope ? One more thing I just purchased a "10 Wheeler" "Annie" D&RGW, what a beauty!!!! With no owners manuel, I was wondering how to take the tender & loco apart for future battery r/c install?  Thanks, many more questions comming later I'm sure.
