Okay, good luck. Don’t forget to report the results.

I found that several of the newest offering by Athearn have these same wheel sets and they have caused trouble on my layout. Like BRAKIE said, it has to do with the wheel flanges, I replaced the entire truck assy and the problem went away.

I didn’t see this posted but one major problem I see many times is how the consist is lined up. I used to have a similar problem when I realized that sometimes when running longer trains that without the proper wieght it of course would derail. I would correct this, check my wheels and make sure everything was free wheeling and that the trucks were lose and had good piviot quality.
Finally as I watched the consist take a turn the cars would still derail, then it hit me. The cars behind the lighter cars were heavier. When I placed the lighter cars at the rear of the consist and the heavier cars were towards the front, guess what! The car wouldn’t derail. It was how I had the cars lined up in the consist; heavier towards the front and lighter cars towards the rear.
It may work.

I’ve noticed something about tyhe way the coupler is set up on the Genesis car. It has an air hose on the left side of the coupler pocket as you’re looking at the car from above. I found that on my layout (all 18" radius curves) this air hose would interfere with the coupler and not allow it to swing to that side. This was causing some issues as the train went through an S curve. While not derailing the car it would cause it to be pulled to one side. I removed the plastic air hose from each end of the car and it tracked better through the S curve. But, I still wasn’;t satisfied. I then used a small jewelers screw driver the break a piece 1/16 of an inch long from each side of both coupler pockets. This improved the situation dramatically because it allows the coupler to swing further to either side. I didn’t have to disassemble the car to do this. The fix was simple and took about 30 seconds.
Sometimes the cause of a derailment can take a lot of study. I just had a Trailer Train flat that derailed at one location and no where else. Looked that car and couldn’t see a thing wrong. Then when I watched it in operation I found that the Kadee actuating wire was riding up on the plow of the trailing unit of the consist pulling it. As the car entered the curve, the wire caught the inside of curve corner of the plow. As the car went through the curve, the wire moved progressively up and toward the center of the plow until the car was lifted off the track.
I’ve had that happen before. Two possible fixes. Remove the plow or remove the pin. I removed the pin.
