I have been using a home made tool using Bill Kronenbergers idea.
Take a small cheap screw driver. Cut a slot ine end and solder a small piece of zscale rail in the slot at an angle.
Now slide a rail joiner onto that piece of rail and ues the toon to slide the rail joiner onto toe end of track.
Saves on fingers, nails, and the many unattractive phrases used when the rail joiner jams onto tender fingers.
