Orin Junction is on the BNSF Mainline in the Powder River Basin in Wyoming .
Every once in awhile, somebody comes up with the most incredible photos.
This one shows what happens when steel wheels on railway cars stop rotating, but the train keeps moving. You will have to scroll down to the bottom photos to see what the wheel looked like while it was still under the car. Incredible!
Apparently found when the dragger went off on the BNSF at Orin Jct about a week ago. Amazingly, there was no derailment. Track speed is 50.
