Hey all. Preparing for the usual group of holiday visitors to the basement. I have the capacity to run two trains at a time on the layout and have two tucked into sidings. I'm contemplating what to run. I have plenty of fancy legacy and TMCC equipped locos that are scale etc. but I wonder if some fun trains such as some TMCC F-3s and passenger cars, AEC and Hot Rod GP-9's etc would be more fun for folks who will be seeing and running the layout for the first time. When attention span is usually limited what would you suggest I run? Any compelling reasons why you feel that way?
Thanks,
Derek
