I had a stubborn section on a curve that looked perfect—gaps checked, joints soldered, feeders in place—but trains kept stalling or shorting randomly. Turns out one of the rail joiners had just enough oxidation to mess with conductivity, but not enough to be obvious. A quick clean and snug push fixed it.
Also had a turnout issue where cars derailed only in one direction. The culprit? A slightly warped plastic tie strip under the frog that lifted the flange ever so slightly.
It’s amazing how small things can throw off the whole flow. Curious to see what tricky problems others have overcome!
