I'm starting a new blog because what I've done may be helpful for others making their own unloading track. I took apart and old Lionel UCS track and used the two outer and Center rail to make up my unloading track. I used those because they are were a little higher relative to the gargraves track to make contact with the shoe. In the picture I soldered the two wired rail sections together and added a power lead from one. Please see my picture from bottom. From my Transformer I added an alligator clip to the common and from the power of my new rail I combined that with an alligator clip to the power center rail. When I run a truck with a coil shoe over the track after adding power it uncouples however, when I run a dump car over my new homemade rails I get nothing no coupling or unloading. What the heck am I doing wrong this time.
