Hello Harun and Welcome!

What I know about coupler heights comes from the AAR (Association of American Railroads) Rule 16 Item E, 12 which states that:

The center height of the coupler for EMPTY cars is 32-1/2" Minimum and 34-1/2" Maximum

For LOADED cars it is 31-1/2" Minimum and 33-1/2" Maximum

There is some pretty good information here:

Hope this helps you out, Ed
