Z SCALE POWERED RAILER Proses powered rerailers transfer power from your analog or digital system directly to the locomotive, allowing it to run, align perfectly, and settle smoothly onto the rails — in seconds. Just place the Proses re-railer on the track, drop your locomotive on the re-railer, run your locomotive as usual — and that’s all. Available in gauges from Z to O, for both 2-rail and 3-rail systems. #modelrailway #modeltrains #rerailer #locomotive #dcc #analog #railwaymodeling #hobbyto
