I read in a forum somewhere that using Kadee couplers made for N scale will result in a more prototypical appearance in HO. Has anybody tried this and if so, what are your results?
I’ve heard that too but I can’t tell you whether this is true or not from personal experience. I can tell you that the Micro Trains couplers (they used to be Kadee before they split into two companies) are a bit overscale in N-Scale but they might look great in HO-Scale. They would certainly be an improvement over the horn a hook couplers used to be standard on HO-Scale equipment. You’ld probably need to get longer shanks than the standard ones or the cars could ened up closer coupled than you’ld like.

KD doesn’t make N scale couplers. They probably meant Kadee “Scale” HO couplers. They have a smaller, more prototypical size head. #58, #158.
There are several options for HO in pursuit of better-looking (more accurately scaled) couplers:
-
Getting rid of everything else for standard Kadee couplers (or clones). Kadee #5 (or new whisker version) are the gold standard. Knuckles are over-sized, but have some resemblance to prototype. Automatic coupling requires coupler centering. Trip pins (remotely resemble a prototype air brake hose) required for magnetic uncoupling. Delayed uncoupling possible but requires smooth low-speed engines, reasonable car weights, trucks that are not too free-rolling, and non-sloppy coupler installations.
-
Scale size automatic knuckle couplers available from Kadee and Accumate (and possibly others). Coupler knuckle is approximately scale size for modern couplers. Will mate with Kadee #5 and similar. Part numbers have been given by other posters. Require greater conformance to coupler mounting height and gentler grade transitions to avoid over-/under-rides. Otherwise, they have the same performance as their larger cousins.
-
Kadee #714 and #711 (#714 is for HOn3). These were the original “scale size” knuckle couplers, and use a scissors design similar to their N scale cousins. Approximately scale for modern couplers in knuckle bulk. Disadvantage is the “slinky” effect caused by the centering spring in longer trains with very free-rolling cars. Will mate with larger cousins.
-
Sergent couplers. An almost exact scale replica of modern (non-shelf) prototype couplers. Knuckle opens by pulling internal ball upwards with magnetic wand. No centering spring, will only couple when couplers are lined up and at least one knuckle is open. No remote uncoupling available so far. May or may not (mostly not) couple with Kadee and other magnetic knuckle couplers.

Prototype couplers were not always their present size. When first
My track has some dips and rises in it that cause the couplers to slide up and down against each other. The scale couplers are so small that they slide apart in one of these areas. I find the Kadee #5 to be the best coupler in this situation as they don’t slide apart from each other.
I have both Kadee #5’s and #58’s on my layout. They really do work together interchangeably, with no problems. I’m not terribly fussy about this issue, but I’ll admit that the #58’s look nicer, and that’s what I’m using now for all my replacements as cars pass through the shop.
Kadee used to sell N scale couplers, before they split off MicroTrains as a separate line. In olden days (early '90s…[:-^]) I had a friend who had equipped his HO equipment with Kadee N scale couplers. They looked great and operated really smoothly. During op sessions, we never had an issue with them. But then, his construction was absolutely bulletproof – everything was really tight to spec, with supersolid trackwork (I don’t think we ever had a derailment, come to think of it…)
So I’d say, if you’re willing to take on the challenge of even smaller margins of error, then go for it!
