Where can I find information regarding coupler adapters for WABCO and standard railroad knuckle couplers? i.e coupling an NYC subway car to an Amtrak diesel locomotive?
I presume you mean the N-2 to AAR adapter as seen here
which is basically just a 200lb casting providing the mechanical connection for buff and draft, and has no trainline, air, or other connections that you would need.
Note that the adapter pictured is intended for the N-2 coupler on MU cars that share trackage with Amtrak trains in Penn Station. Subway car adapters might be different in mutual height or other characteristics.
Some information on these is available from suppliers or on specialized transit forums, and these would be the logical places to find specific information if you have a particular practical use in mind.
An alternative that sometimes gets used is to have a pair of buffer cars, with a standard railroad knuckle at one end and the special coupler at the other. One buffer car goes in front, the other behind the non-standard equipment.
It is much like modelers in the past (maybe still do) would have a car with a KD at one end and an X2F at the other.

Yes I meant something like that. Thanks for tho photo too.
LIRR had one or two SW1001's with a specialized coupler at one end to pull M-1 cars out of the East River tunnels in an emergency.
In N scale, that is KD/Rapido combination. I use it often—call them "transition cars."
