Metal rail joiners are a poor conductor of electricity. As shown in this video, soldering the rail joints improves electrical conductivity and provides more reliable locomotive operation.

  1. I have some “Solder-it” silver bearing solder paste that can be used with
    a butane hobby torch. Are they, (the torch and paste), ok for track and wiring soldering on a layout?

  2. Using a hobby knife will remove the projections above the surface of replacement ties just fine. However, because the rail joiner extends BELOW the rail level, it is often difficult to slide full-height replacement ties underneath without creating a lump. That's probably why sectional track doesn't have ties beneath the rail joiners in the first place.

    I keep a piece of coarse sandpaper handy, and use that to thin the entire thickness of the replacement ties. It doesn't matter if you sand off the top or the bottom of the replacement ties, it works just as well.

  3. Caution! Sometimes you can induce a vertical curve into your track if you're not careful when you solder the rail joiners. Same is true when you shove in the filler ties where the joints are. I know you alluded to that but it can't be over stressed. Vertical curves are as much a problem as miss-aligned joints.
