Tech 4 Railpower 350 Programmable Power Pack

Open the throttle, and an impulse circuit delivers a burst of power at the right moment for smooth, jerk-free starts. Set top-end voltage for exact speed control at every position on the throttle. Best of all, you get the same peak performance from every engine. Optional Walkaround Throttle (#500-251, sold separately) with modular plug lets you work at trackside or enjoy the company of another operator.
