I like to re-inforce my rail at the ends of my modules, because I have had people in a hurry to tear down after shows, peel up rails off the flextrack in their rush to get their modules disconnected. So I used .03" brass EDM tube soldered to the rails. I drill a .8mm hole through the roadbed and plywood right next to the rails about 1/2" from the modules edge for all tracks. I cut a 1" length of tube, and bend the end 90 degrees. then flush cut it. I press it through the hole, so the flush cut 90 degree contacts the rails, then solder it to the rails, and bend over the wires that stick through the bottom. They act as both rail feeders and rail stiffeners, preventing over anxious people from peeling up my rails. After you have been on the show circut for several years you will know what having peeled rails is all about. Does it work? Heck yeah! I had a module next to a guy who was so eager to get his module, and get outta town, that he forgot to remove the splice track, then unclamped the modules and zipppp! He peeled up a 15 inch strip of rail from 2 tracks off HIS module. I had a slightly bent piece of rail on the last 1/2" of my module, which I was able to straighten without fuss. This poor 'some-itch had to re-lay the track on the front of his module and replace a turnout! Happy Happy, Joy Joy!
