"Think how much money we can make if we can run em 150 at a time"

That's a pretty good bend that has to be handled with care.

A broken air line? Maybe the one that keeps the rail wheels down and the highway wheels up? I seem to recall thats the problem CSX had with those trailers, and the main reason CSX quit running them. Its a bitch when those hiway wheels come down on the rail....

Sandusky fire Capt. Brian Cowie said the train was either stopped or moving very slowly when the derailment occurred at about 4 p.m. The engineer tried to start or speed up the train, but it wouldnt move. Looking behind him, he noticed the cars off the tracks.

Kyle Trimarche, a Triple Crown foreman, said a broken air line may have caused the derailment.
He said the train had 150 cars and that getting all the cars back onto the tracks would be a long process

Itll probably be a couple of days until we get everything cleaned up, he said.

The cars that tipped were empty, but others two or three cars away, on the other side of Venice Road, had full loads, some of them hazardous. He would not say exactly what was in the cars.

In September 2009, 11 Triple Crown trailers semi trailers outfitted with track wheels at one end and hitched together to form a train partially tipped over on the same curve. The trailers were empty.

In October 2007, a similar incident involved 17 Triple Crown trailers, carrying toilet paper and paper towels. That was eventually traced to a too-short air line connector between two cars; the line came loose as the cars moved around the curve.

As in the other two incidents, rail cars lay tipped at an angle toward the inside of the curve, though some lay on their side further on. One car knocked over the crossing gate and lights on the east side of the crossing

The highway wheels don't "come down" these days.

They ride on detachable rail bogeys.

Triple Crown RoadRailer® trailers ride on rail bogies
with slack-free coupling, minimizing the risk of cargo
damage that could be caused by shifting freight.
Each RoadRailer® is backed on the rail track where the air-ride system raises the trailer above the bogie. When aligned, the air system lowers the trailer onto the bogie and lifts the tires off the track.

A broken air line?

Causing a stringline derailment possibility when the rail brakes shoot in a tight curve, heavy locomotive loading, light lading situation.

Maybe the one that keeps the rail wheels down and the highway wheels up?

No, there is no rail wheels down/ highway wheels up air line/mechanism like there used to be.  As your picture shows, the rail wheels are independent and always down. The trailer lifts to the bogie with the air lift. No air, no lift.

I seem to recall thats the problem CSX had with those trailers, and the main reason CSX quit running them. Its a bitch when those hiway wheels come down on the rail....

 

The highway wheels  fail up. (Air lifts the trailer off the wheels.) Opposite of what the original all-in-one highway/rail bogies did.

CSX quit running them because they discovered they couldn't compete with superior LAMCO methods. I think.
