Here is everything you need to get started with TrainMaster Command Control. The CAB-1 Remote Controller (6-12868) allows you to walk around your layout while controlling all of your TrainMaster Command Control equipped locomotives and accessories. The TMCC Command Base (6-12911) receives the signals from the CAB-1 and sends your commands across your layout. Only one Command Base is needed per layout, regardless of the number of track power blocks you are controlling. It is the perfect way to start enjoying the benefits of the revolutionary Lionel TrainMaster Command Control system. (Power supply not included.)
