Another good question. If it was legit and the truck was stalled out on the tracks, were they outside checking under the hood or what? Sitting three in the cab while truck sat on the tracks seems improbable. Also who cant see or hear a train coming.
Modern garbage trucks are very sophisticated and have robotics. Can you even fit 3 guys in one?
Oh, they are WAY quiet for there size and speed. I got caught on a trestle once, it was on us like stink on excrement. It was a real life Stand By Me scene, the closest I’ve ever been to death.
