Was the first generation all-in-one command station/booster/throttle. Zephyr was designed for beginning, intermediate and advanced model railroaders. It's simplified interface was easy to use and had tons of features. The set contained a DCS50 command station/booster/throttle, a PS315 power supply and an LT1 LocoNet tester. This was the first product with Jump Ports that allowed a smooth DC controller to be used as a throttle to control DCC locomotives. Discontinued in 2010.
