There’s only one ZW. No single product has come to symbolize the legend of Lionel more than the Lionel ZW. Molded to original dimensions in classic phenolic resin, the ZW can run up to four trains at the same time on different layouts, plus accessories. The two engineer-type handles provide independent control of two variable voltage circuits, each with built-in whistle, direction, and bell controls. Two additional accessory circuits can be set by means of dial-type controls to any desired voltage. Or if you prefer, you can control all four outputs with a single handle!
ZW controller can be powered by any combination of one to four 135-Watt or 180-Watt Lionel PowerHouse Power Supplies
And if you use the TrainMaster Command Control system, you can adjust each output using your walk-around remote control up to the level pre-set by its corresponding ZW handle
