When I was at Kato I was tasked with providing the dimensions for a coupler pocket that would work with a Kadee #5.
The NMRA "Standard" was designed for the Baker, Devoe and Mantua couplers. Now wasn't THAT useful!!!!

Yes, I have seen those pockets before. The problem is that
Kadee's invention made the standard obsolete. Now that Kadee
is the 'standard', the NMRA could update that RP!
