Train hardware has fascinated me since I was a kid (lifelong foamer here), but what really baked my noodle was the realization that these chunks of steel small enough that a single person could carry are strong enough to pull over a hundred 30+ ton cars and the thousands of tons of cargo each car holds for thousands of miles. It's one of those things that I understand, yet still blows my mind.
