Why do you use Kadee couplers on British and European cars?
• Multiple answers to this one. Some British coaches, like the Southern Bulleid, were actually fitted with knuckle couplers, and their buffers were locked back out of the way when running as a set. On all the models, the Kadee couplers allow the train to run minimizing the problem of buffer locking, they make it far easier to couple and uncouple, they can be pushed with no problems, and also allow the corridor connectors to be just touching all the time with no big gaps.
