Listed & described below are RailCar|RollingStock Couplers as typically used on historic & modern Industrial+Mainline+Mining+NarrowGauge+Plantation+Transit railways. Couplers are often known by more than one name. Compromise couplers or cars are used to transition between coupler types.

AARD+AARE+AARF+AARH Couplers

Also known as Janney, Alliance, American, APTA, ARA, BuckEye, Knuckle, National, MCB, Sharon couplers
SubType AARD used on Historic 1893~1900 Stock to mate with LINKpin couplers via a SlottedKnuckle
SubType AARE used on General Freight Locos & Wagons
SubType AARF used on HazMat & Rotary Wagons to avoid AccidentalDecoupling, AKA InterLock couplers
SubType AARH used on Passenger Locos & Wagons to avoid SlackAction, AKA TightLock couplers
All AAR SubTypes will mate to any other AAR coupler
