The title of the tread does not say scale in it, only Legacy Big Boys. And Lionel did make Legacy Big Boys that weren't scale, hence my point of your sweeping comment about big articulated locomotives when someone talked about O-27.
True, but if you noticed, the original poster did mention in his first post a length of approximately 32". As the Lionmaster BigBoys are listed in the catalog at least 29" ( 3 inches smaller and quite a difference actually), and not to mention also the new Vision Line Big Boy being featured prominently in recent discussions, it is a foregone conclusion he was, in fact, referring to the scale versions.
