An entire DCC system in the palm of your hand! This 1.5 Amp system can operate 2 or 3 HO/OO sized trains, or 4 N scale trains. This cab provides all of the capability and ease of use that youve heard about in NCEs Power Pro system, at an entry level price. Installation is a snap. Hook two wires to your track and plug in the cab. Youre off and running trains!
