Working with rail joiners is difficult for many model railroaders. Rail joiners are the weakest electrical connection on any given model railroad layout. When tightly fit, rail joiners serve as fine electrical conduits. However, over time, rail joiners tend to expand and loosen, which results in worse electrical conductivity. However, better rail joiners are possible.
Trains.com Director David Popp demonstrates how to achieve better rail joiners on your layout through soldering using Peco code 100 track.
