RichD1 Posted February 14, 2021 Share Posted February 14, 2021 I’ve inherited a whole stack of goods wagons, mostly kit built and they all have a strange coupler fitted. Can anyone identify them and were they any good? They appear to be magnetic type couplers. Is it worth trying to get them all up together? Are they still made as several are missing parts. From looking at them I can’t see them being as good as Kadees for the ability to push the wagons around the yard without coupling again.

RexAshton Posted February 14, 2021 Share Posted February 14, 2021 They are Sprat and Winkle couplers and work like an inverted tension lock. They and the magnets to uncoujpkle them are still readily available from Model Signal Engineering. Their continued use on many exhibition layouts is a testament to their ease of use and reliability. They can be uncoupled either magnetically or manually. The photo shows two different version, the ones with the small curved tag on the top allow for advanced uncoupling. The ones without don't but can be easily modified by soldering a wire 'tag' in place. 1 1 1 Link to comment Share on other sites More sharing options...
Michael Hodgson Posted February 14, 2021 Share Posted February 14, 2021 It is quite common for the bar these couplings engage with to be fitted to the buffers rather than as a loop as seen here. That does look rather odd Link to comment Share on other sites More sharing options...

That does look rather odd I've always thought that Spratt & Winkle couplers with that savage great hook are every bit as obtrusive as the tension lock ones they often replace. They may have been acceptable when first produced but I think that there are much less obtrusive alternatives available now.

RichD1 Posted February 14, 2021 Author Share Posted February 14, 2021 Thanks for the advice. The trucks have had any sign of standard coupling fitting lugs removed. How easy would it be to fit Kadee couplings? Richard Link to comment Share on other sites More sharing options...
RMweb Gold D9020 Nimbus Posted February 14, 2021 RMweb Gold Share Posted February 14, 2021 You would need to fit a "standard" (non-NEM) Kadee and its pocket. These are usually screw-fitted so you would probably need to fabricate something. Alternatively, I believe the pocket can be glued in place, though this is less secure. However you might want to fit them, the height of the wagon base will determine what needs to be done. If you don’t have one already, you will need a height gauge—correct height is vital for correct operation. 1 Link to comment Share on other sites More sharing options...
Derekl Posted February 14, 2021 Share Posted February 14, 2021 Search RMWeb for "Kadee" and you will find myriad pages of advice on fitting Kadees to all sorts of stock. Fitting to wagons is not difficult in my experience. Link to comment Share on other sites More sharing options...

DT You miss the point, these S&W couplers can be easily and quickly adjusted to be a standard height above rail level and operate reliably. Standard Tension locks don't and can't, Spratt and Winkle have the tension locks disadvantage that you can't lift a single vehicle clear, which Peco H/D and Kadees allow. Kadees can be adjusted for height but not as quickly and easily as S&W and are generally superior but they are a lot more expensive... Obviously if you have 100 locos 3 coaches and 21 wagons it makes no sense to change the rest of your fleet to S&W couplers but for a shunting layout they make an awful lot of sense. 1 Link to comment Share on other sites More sharing options...

Actually, no, I haven't missed the point. S&W couplers may indeed work well. The point I was making is that they are visually very obtrusive. They may well be ideal for a shunting layout provided you don't mind all your wagons having a great big hook sticking out under the bufferbeam at each end not to mention the large loop. I personally would find it unacceptable. Kadees I'm sure work well for vehicles that use buckeye couplers and don't have buffers, but they too look pretty awful on most UK steam-age freight stock. Having said all that, couplers in 4mm scale are invariably a compromise. DT Edited February 14, 2021 by Torper 1 Link to comment Share on other sites More sharing options...
brossard Posted February 14, 2021 Share Posted February 14, 2021 Agree with Torper. Kadees do look awful on UK stock but then most other couplings, apart from prototypical, look pretty terrible too, not least the tension lock. Kadee have the advantage of at least looking like railway equipment. They also are generally fairly easy to install, are reliable in service and can be uncoupled using a magnet or manually.
