I have a kinda dumb question guys...Is the Lionmaster challenger scale sized?
All the LionMaster line engines are smaller than scale. They occupy a space between full scale engines and the so-called traditional engines as far as size (although some traditional diesels are scale in size), and have more detail than traditional engines. They're designed for folks with modest-sized layouts, who still want all the bells and whistles, so to speak, and detail, but don't have the room to run the full scale stuff (which can be extremely large).
The current LionMaster models have all the top-of-the-line Legacy features, just like the full scale Legacy engines. They are many folks (including me) who wish Lionel would make more of them.
