{S-Scale List} Help needed with OMI USRA 462 electrical shorting problem

[Edward Sauers]

Group,
 
I am having a problem with the rear pony truck wheel shorting out against the 
inside of the steam cylinders (front inside edge of the cylinders) on my 42" 
curves. If anyone has run into this problem and has come up with a solution, 
please share with me what it takes to eliminate this problem. I could remove a 
small amount of brass on the inside of the cylinder but would like this to be a 
last resort solution only. This engine really runs very well otherwise!.
 
Thanks
