Hello
get only Micro Trains couplers.
They are like the advertissement say the "Cadillac" of the N scale couplers.
They just need precise positionning and height but they are really worth the effort.
One more remark, even if they mate with some other brands of knuckle couplers, problems can occur to couple them or uncouple them when mixed, so anyway use only Micro Trains couplers.
