FWIW, I recently purchased 12 (twelve) 072 turnouts and don’t have any issues with derailing. I haven’t heard of a widespread problem with the 072 turnouts other than the Fastrack switches in general can be hit or miss with electronic components. Actually, I have 2 which work fine with the wired remote and the trains roll thru with no issues but the 2 problem units have a bad board and won’t go into program mode.
I would exchange for another 072 seeing as you have one that works.
@Steims My switches are running off track power but I didn’t install a jumper. Are they in there standard and need to be removed if wiring a separate power source? I removed the wired remotes and don’t recall seeing a jumper.
