In their 2006 Volume 2 catalog, Lionel officially unveiled the new TMCCII "Legacy" system. TMCCII promises to revolutionize the way people control and play with their model trains, by adding more features that mimic prototypical operations of a real railroad, and subsequently, a real locomotive. TMCCII is backwards-compatible with existing TMCC modules, and can work simultaneously with CAB-1 controller.
Like TMCCI, the core of the "Legacy" system is the handheld remote. The CAB-2 remote features, among other new functions, a back-lit LCD screen, back-lit LCD touchscreen keypad (which can toggle between numbers and control icons), a Feedback mode (the controller rumbles reflecting the struggling engine), and rechargeable batteries.
The first locomotive to feature TMCCII is the Union Pacific Big Boy. At the moment, only the CAB-2 remote and command base are available, with additional modules being released in due course. The second locomotive that was released was the American Flyer New York Central which arrived back in April 2007.
