The Hornby catalogue has a list of symbols at the front, one of which means (in Hornby's own words) "has NEM coupling pockets". To be an accurate description, therefore, the pockets would have to meet some NEM coupling pocket standard, though not necessarily NEM 362: there is NEM 363 as well (plus NEM 355 (N) and NEM 358 (TT) — these are actually identical). Bachmann have a similar symbol which is said to mean "has NEM couplings" which is actually untrue for any OO model it appears against (I assume the Arnold-type N gauge coupling is a standard, but don't know). There are NEM standards for couplings — 359 for TT and 360 — the hook-loop design — for HO. Indeed and if Hornby really are describing coupling pockets at a different height as "NEM coupling pockets" they (or the retailer) probably are violating consumer protection legislation. The NEM itself has no legal force (and applies specifically to H0 and S scale) but it is a published standard and does specify height above rail so, if you say you're conforming to it and you're not, then your product description is misleading. FWIW The actual N gauge coupler head specified in NEM 356 is indeed the Arnold Rapido type but the TT coupler specified in NEM 359 is not one I've ever come across . When I modelled in H0e I did use Microtrains couplers (same principle as Kadees and used to be Kadee until the two brothers split the business between them) but just bought them with their draft bozes and fitted them accordingly.

I mentioned above that Kadees were frustrating because of the fore and aft slop. Not so bad for goods stock maybe but terrible if you are trying to get your coaches to have a reasonable gap.

I couldn't agree more. I came to the conclusion many years ago that the only virtue of the NEM 360 hinged loop coupler (referred to by Australian modellers as the "dunny seat" coupler) is to make tension lock couplers look good in comparison. They don't want to couple, when they are they don't want to be separated and have a nasty habit of jamming in a way that threatens every detail at the ends of vehicles when you try to twist them apart. Also, every manufacturer seemed to have their own "interpretation" of the NEM standard with (pre HJ) Jouef's being about the crudest Having previously modelled N. American Railways, in the form of a switching layout, and being very amused by the standard "horn-hook" couplers that were always instantly replaced. I went over to Keith and Dale Edwards' patent couplers for my French layout and, though they're not perfect, I have never regretted it. You really do need to get the heights right though When I was a child I lived about a mile away from a railway yard and the weird bouncing back and forth of loose coupled goods wagons , mostly coal, meant that at night I often heard "the sound of shunting trains, ringing and rumbling, softened almost into melody by the distance" in H.G.

The NMRA did specify a standard for dummy knuckle couplers in RP-21.1 issued in 1957. It was though about 25% larger than an actual scaled down version of the prototype as were the original Kadees. Specifying a standard "draft box" was possible and more useful. The NMRA did that at the same height (to scale) as the real equivalent. Given that the NEM box is designed to sit under the buffer beam of a UIC standard buffer and drawbar to take non-prototypical couplers, the height has to be different (which is why the Kadee NEM couplers are cranked) so I don't think a global universal solution would be possible, any more than it is on the big railway.

AFAIK All Bachmann wagons from the "Blue Riband" range were wrong, (this was when Bachmann re-tooled the old Mainline range with a finer chassis and other improvements) many have since been re-tooled with a lower mounting but some may be still on the market with the original position (confirm?) Again AFAIK Any Bachmann wagon still in the 33-XXX series, China Clay, Salt, Toad etc. will have either screwed on Mainline fit T/L on 4-wheelers, or moulded in T/L on bogie vehicles. (unless this has changed recently. The photos on the website suggest otherwise.) The Bachmann 45XX is wrong, both too high.

Mantua was like a reversed tension-lock but the hook was very far inside the loop. It was one of several designs from an NMRA committee led by Paul Mallory charged with developing a standard coupler in the 1950s when every manufacturer had their own mainly incompatible types. The version with an integral plastic spring (which I believe was the X21 though commonly known as the X2F) was easy to manufacture so taken up by most manufacturers. It was though never accepted by the Association's members (I don't blame them!) so was never an NMRA standard leaving plenty of scope for manufacturers to adopt their own specs . Most RTR and shake-the-box "kits" were supplied with them but fortunately mainly in a draft-gear pocket, which is standard, into which a Kadee no. 5 shank could be fitted instead. Fitting Kadee's own draft-gear pockets to "craftsman" kits was straightfoward with the height gauge. The problem I do recall was the manufacturers' habit of fitting either a purely cosmetic dummy coupler, or nothing at all, to the front of steam locos. For a switching layout that was not helpful and filing out the mazak to fit a Kadee pocket was not my favourite task mainly because I've always been fundamentally incapable of filing a flat. 1 Link to post Share on other sites More sharing options...

In this particular case I smell a strong possibility that some thing included in the patent as new art was actually pre-existing. If so, the patent holder wont risk a legal challenge. Kadee's patent was for the method of coupling and uncoupling which, though it resembles it in appearance, is very different from how a real AAR coupler works and relies on a horizontal hooking and unhooking system. A standard that covered centre height and the shape of the coupler head and knuckle was already established. The profile was defined by the NMRA's RP-21.1 issued in 1957 though it was about 25% overscale and this was followed by Kadee (their couplers will couple to dummies) . But, while that was fine for dummy couplers - where the head is a single casting so the knuckle doesn't hinge open. a working coupler needed a way of geting the knuckles to mate, to stay locked in tension, and to be released for uncoupling. A 1/87 coupling pin that dropped into position when the knuckles closed as they came togather, together with a working lifting lever to uncouple wasn't a practical proposition for a mass produced item (I wonder if anyone made their own)* Kadee came up with a practical way of doing that could be completely automatic and that was what they patented. It's worth remebering that Peco was partly, possibly largely, developed on the back of the royalties that they got from Hornby who adopted Sydney Pritchard's patented Simplex coupler. That is actually far simpler than Kadee but was still patentable and Pritchard did mount a successful legal challenge against Trix who made their own coupler working on the same principle. * Sergent Engineering's couplers do work in the same way as the real thing so, if they are patented, it would be their use of a steel ball to replace the coupling pin that drops into a hole to lock the knuckles closed when they mate and the magnetic method of "liftng the pin" to allow the knucle to hinge open and so uncouple. Their development probably relied on the arrival of Neomydium magnets to enable the uncoupling "wand" to lift the steel ball. However, just like AAR couplers, Sergent couplers are not automatic, as they make clear in their website. They will couple with scale dummy couplers (only one of the knuckles has to be open for an AAR coupler to work) but not with Kadees and their clones.

Jeff Smith Posted April 4, 2021 Share Posted April 4, 2021 The plastic version from Bachmann works identically to Kadees, the later versions have a wound metal spring for the jaw instead of a plastic leaf spring.

Pacific231G Posted April 6, 2021 Share Posted April 6, 2021 Hi Jeff Are you referring to the Bachmann Ezmate 'clones' for use on N. American cars in a standard draft gear box or the type designed for use in NEM coupler boxes. My own experience with the latter has not been positive. I picked up a load of unused ones for next to nowt at a show and tried them on several vehicles but they've all since been replaced by proper Kadees. Because the heads are rigid they do rely on the coupler pocket being able to move from side to side. but that movement seems less conducive to magnetic uncoupling than the swing of a coupler shank within an American type draft gear box. While sorting out some MRNs from the 1950s and 60s I found an article from Feb 1965 about Kadee Couplers. What I hadn't realised is that at that stage they were making two types of coupler- Magne-Matic, which is the sort we're now all used to, and Magne-Action which was a magnetic version of the X2F, described in the article as "similar to the couplings on Airfix OO freight trucks" . This used the same uncoupling magnet as the Magne-Matic. Basically, a fairly heavy looking steel pin- much heavier than that on Magnematic couplers was mounted beneath and to one side of the coupler head. This also offered delayed uncoupling but looks even more ungainly than the normal X2F. I assume that Kadee dropped this type of coupler when the more realistic looking Magnematics became a de facto standard amongst "serious" American modellers.

The first standard might be drawbar height, by which the coupling drawbar hook is either effective, or not. It happens on the Big Railway as well, with headstock height all over the place. Haha yes. I recall a certain member of this parish taking a 1:1 scale Virgin class 57/3 from New St up to Soho to trial coupling to a Central Trains class 323. They didn't match and that was when we operators discovered that Virgin dellner couplers on 220 221 and 390 were designed to be at a different height to other operator's dellners. I am assuming "Supaned" remembers this. 1 1 Link to post Share on other sites More sharing options...
RMweb Premium BR60103 Posted April 8, 2021 RMweb Premium Share Posted April 8, 2021 We toured the GM (EMD) works in London, Ont when they were building locos for EWS. To be tested with North American loads or be hauled (I forget which) they took off the buffers and mounted (in the same boltholes) a \_/ shaped beam with a knuckle coupling at the bottom. So even in the same scale, N.A. couplers come out below the bufferbeam. Pictures were forbidden on the tour. 1 Link to post Share on other sites More sharing options...
roythebus1 Posted April 10, 2021 Share Posted April 10, 2021 I use Roco/Hornby close couplers on bogie stock with Kadees on the outer ends. On some of the Bachmann stock I've replaced their KK mountings with the Kean systems units which brings the NEm box out at nearly the right height, more nearly than the Bachy offering. I've just been online to stock up on Kadees and it seems they're in very short supply in the UK at the moment. Hattons no stock, Gaugemaster no stock...Express Trains had a few in stock and I've probably wiped out their stock! Another vicrim of the B word that we shouldn't mention on here.

Since Kadee is a U.S. company I doubt that "the B word" has anything to do with it directly. More likely a combination of: a) A step increase in railway modelling activity as a result of lockdown. A lot of items are in short/no supply. Many Peco products are especially hard to come by, and they're made in the UK (though I believe that Peco themselves have also said that they've been affected by restrictions on their production capacity due to "the C word"). b) A change in the rules/processes around collection/payment of VAT and customs duty*, instituted by HMRC in the latter part of 2020. This may have been peripherally due to "B" but it was affecting shipments of all sorts of goods from U.S. and Canadian suppliers amongst others before 31/12/2020, which was when the transition period with the EU ended. Some have stated that they will no longer ship retail orders to the U.K as a result. The issues have been widely reported in the press since 01/01/2021 (e.g. here and here) although, as I say, the problem had existed for shipments from non-EU countries prior to that date. There is some discussion about the impact on Kadee prices in the UK of the new process for ordering from overseas on this thread. It wouldn't surprise me if this is also affecting supply levels, at least while suppliers and importers (and maybe even HMRC) get properly to grips with the new process. * Although model railway items should be zero-rated for import duties (but note also Charlie's reference to being charged import duties on his last Kadee order). 1 Link to post Share on other sites More sharing options...

I also have some Hachette Mk1s (remarkably similar in some respects to the Bachmann offerings). The pockets on these are too low, but a paper or very thin card shim seems to have sorted that. They certainly remain coupled on my flat (and, if I say so myself) reasonably smooth track. Locos: the Bachmann Crab is correct height front and rear. 1 Link to post Share on other sites More sharing options...
