Was the cause of the out of spec. wheel sets, usually due to the migration of, one of the wheels or both of the wheels? Are there brakes on these axles? When in use, is there a temperature difference between the axle and the wheel? When the wheels are pressed onto the axle, are any chemicals used to prevent migration (similar to a bearing retaining compound)?
it took several minutes to determine the narrator was saying "widened wheel set" – every time it sounded like "waadin wheel set" as if it was a brand name or something – slow your speaking cadence and annunciate clearly when you have such a thick regional accent like that
Why are these width checks being ignored? 30/80 total out-of-limits sets before an accident requiring fleet checks is pretty poor, not the worst, but certainly a poor show. Are the engineers being over stretched? Are the bean counters cutting corners? Is the importance of this check being undervalued?
This is interesting!

Very interesting. Will you guys be releasing an investigation into the Ohio derailment?
Tryin' to find something to tide me over til the next USCSB video and…
Those 7000 series Kawasaki cars are really nice to ride in even with all the issues, glad there were no injuries
So, installing some type of laser measuring tool that could confirm the wheel spacing while at the yard daily isn’t possible?
The NTSB needs to get the Chemical Safety Board to animate its videos.
Very straightforward and transparent video.

So did they come from the factory this way or is something causing the wheels to migrate? I have the sense we haven't found the root cause here
Thank you for sharing.

An accident that undid itself thats mathematically nuts.
After pressing on with proper interference , tack weld the wheel to the shaft .
If the wheel migrates the tack weld will break and is easy to spot .
it's litterally the kind of deraillement and rerailing I get with my model trains, but in real life.
That hop when it rerailed was more than my school bus did when it went over a speed bump without slowing down
Maybe at some point i the future they should switch to standard gauge.

This is exactly how the wheels on my HO-scale train cars behave. Derailed and then rerailed by a switch. I had no idea they were that realistic.
