In this how-to video from Model Railroader magazine, Managing Editor David Popp shows you some easy techniques for laying derailment-free N scale track on your model train layout. David shows how to cut flex track, work with Peco rail joiners, solder rail joiners, file the joints until they’re smooth, and add feeder wires. Using these techniques on your N scale layout will keep your trains running smoothly and on the track. Most of David’s techniques will work on HO or O scale model railroads also. Then he shows some trains in operation on his N scale Naugatuck Valley New Haven layout.
