I did not mention Kadees because I do not think the OP wants to go in that direction. I sure agree switching with the highrail KC's, regardless of brand takes a lot of manual intervention, the Kadees solve that. The most irritating thing to me with the KC's is that even on a 30"R curve the couplers will still completely miss each other when backing up to couple.
I briefly considered Kadees. They work fine on my layout body mounted on freight cars. Not so much on the passenger cars, but then I do not switch passenger cars, I run them in preconfigured trainsets. I have a number of the older AM full 80' length lightweight passenger cars. They will not run with body mounted couplers on my layout.
