Sometimes the issue isn’t where we think it is.
Maybe your locomotive was hesitating—but it turned out to be a tiny spiderweb across a sensor. Or a flickering light that only needed the plug rotated 180 degrees. Or the train wouldn’t run… because the cat unplugged the power supply.
Those “it can’t possibly be that” moments are the best… and the most humbling!
I once spent over an hour tracing a power issue across the layout, only to discover the culprit was a slightly loose power brick at the wall. I bumped it with a chair earlier and didn’t even notice.
And yes—pets are repeat offenders. My cat once jumped onto the benchwork and gently unplugged the throttle cable… mid-ops session.
