You definitely know it's a movie because their laws of logic do not apply to air brakes. Or the idea that they could just evacuate and disconnect the lead locomotives pulling the train to destruction.
Here’s 2 ways they could have stopped it. After absolutely demolishing the caboose 4920 could couple up with the car behind and bring it to a stop while it’s still going slow. Or they could have not coupled 4920 earlier and couple it up around Jackson summit stopping it
Damn… poor Tucker… also wow I’ve never seen a knuckle coupler break like that. I honestly expected it to rip the cabooses knuckle straight off, not for the knuckle’s clasp to just snap off like that.
