Car carrier full of luxury autos gets stuck at a railroad crossing and is hit by a train

Florida.

Jesus. The dudes filming it sound like bigger train wrecks than the incident itself.

Another view

The Brightline has been around for a few years and is already known for killing dumb people who can't stay off the tracks. The powers that be want MORE high speed rail in South Florida but its clear that all the cars, dim people and trains just don't mix.

mckenziescarsandadventures2020 seems to make some valid points in OP's link:

Here is a thought. The truck crossed the tracks when there wasn't a train and got stuck at the light. Then the gates went down and the truck couldn't move either because traffic wouldn't let him or because he didn't realize that the gates had dropped on the trailer. Now as someone with a CDL I wouldn't have crossed those tracks and stopped on them to begin with and if the traffic light turned red... tough shit. Run it or get hit by the train. Regardless. That intersection is very poorly set up for trucks.

Convoy!

Why wouldn’t an alert have sounded on the train to warn the engineer that a vehicle was on the track, giving him time to hit the brakes?

By "let anyone drive these things" do you mean the truck driver or the train?

The truck driver. He could have stopped before the tracks. I assume his trailer wouldn't be protruding out into the intersection behind him. But the guy in the comments section / R5 has a point. It is a poorly designed intersection.

Uh oh. Somebody's getting fired.
