@Big Jim and @3rail my post has been edited to be more clear. I had thought that a male and/or female articulated coupler that connect to the common truck would be included with any maxi stack. When I read the most recent manual associated with my CSX maxi stack, it led me to assume it had the components, with the exception of the common truck, allowing it to connect to another maxi stack to form a unit upon disassembly. the NW I bought was part of a set,as 3rail alluded to. I figured if they’re being offered as single units then they must have the items, again exception common truck, that would allow you to make them into a unit. Considering the place where I bought the CSX one, I thought it possible as well someone could’ve opened the box and taken those components.
im sorry the original post was so unclear, I was rather frustrated and not thinking clearly or expressing myself as clearly. I’m not an idiot, I guess I was in denial Ha. I’ve only gotten into freight in the last 2 months and intermodal a month ago. When I bought the CSX maxi stack- I didn’t even know they had the ability to become units with the common truck- I just thought they couple normally.
