dreadnaught ends

[NW Modeling List]

Mike:
 
Count the ribs (the "peaks", not the "valleys") bottom up*; put a "/" (or  
"-" if you prefer) when you cross a rivet or weld seam.
 
*Some people like to count down, some to count up.  For example,
 

 
Is that a 5/4 or a 4/5?  The answer is "yes."
 
Is this end a 4/3/1 or a 1/3/4?
 

"Yes".
 
For some reason (maybe because in most cases the larger number of ribs was  
on the bottom, and we like to "count down", that's more common, it would  
seem.
 
Anyway, I hope this helps.

Can anyone explain dreadnaught ends on  boxcars?  I think I understand the 
reason---corrugation makes it stronger  without taking up much space, but 
how are they named?  I have seen 4/4  but I have no idea what that refers to.  
Other information appreciated as  well.
Thank you,
