Atlas switches can throw themselves under certain conditions. Before I had installed their nonderail circut boards with a certain diode Atlas recomended, I was running my new Burlington Zephyr.
Long story short, it went into a unfinished siding and crashed 40" to the concrete floor.
surprisingly, I was able to get it running again, with a few small dings and scratches.
I must say it runs but has had issues ever since.
It should have been destroyed, But it still runs most of the time today. Lionel builds a robust product.
