Caboose Wheel Set Mystery

[NW Mailing List]

Dave:
This could be a U-1 wheel.  In the mid-70's, there were a multitude  of
wheel failures caused, I believe, because the wheel had been made
with too much carbon.  Instructions were sent out to replace  these
wheels.  Most were applied to cars with 70-ton hauling capacity.
With the wheel set removed, carmen would then  burn a hole in  the
wheel to make  it useless.   
 
Once shops had inspected the cars and  found that  cars didn't
have the U-1 wheel, or if wheels were replaced, a yellow ball was 
applied to the car -- either painted on or an adhesive sheet with
the ball on a blackground was attached.
