Re: Type "D" vs. Type "E" Coupler Tests

Dave, you asked:
 
"Did the ARA report cite anything about the actual value of the maximum strength for either type?  Essentially is that 40,000 lbs. greater strength a 1% improvement or something like a 20% improvement?"
 
Dave,
 
The value of maximum strength for the Type "D" was 295,000 lbs., while the Type "E" was 335,200.  An 8.8% improvement. 
 
Kindest Regards,
