RussellH from this forum (Russ) kindly sent me a few sample couplers he makes for me to test out. These are (I think?) best described as 'short shank rapido couplers'. If that's not the correct term someone let me know please!

The idea is that they can fit into the old fashioned sockets with a spring and will shorten the gap between vehicles to look a bit more prototypical.

I tested the sample couplers in two Graham Farish coaches (a royal mail MK1 BG (Poole made) and an Intercity Mk1 FK (China made) and found them to be successful!  They ran fine on radius 3 and 4 curves on my layout with no buffer locking or derailments. I shall now be ordering some 1.25mm couplings from Russ to convert more of these old coaches.

This pic shows the gap between the converted coaches:  The I/C FK has 1.25mm couplers, the Royal Mail BG has 1.5mm.



The photo below shows the gap between two old coaches (again one Poole made, one China) with the standard farish couplers! You can see it is massive. Ok, it's not quite from the same place / angle as the first photo, but you get the idea about size difference...



This one is a bit blurry, but you can see from above that the gap is much reduced in the converted coaches (both are Mk1s, all B4 bogies)



OK, so the coaches themselves are of course not as good as the very latest Blue Ribband ones with new tooling and NEM couplers, but the gap between the converted coaches was only marginally more than these two Blue Ribband Mk1s with standard length NEM couplers:



Sorry this is a bit blurred, but it shows a 1.25mm coupler on the MK1 FK (bottom) and a 1.5mm coupler on the Mk1 BG (top)



Just a few words, I didn't test these on Radius 2 or 1 curves. I only tested them for a short run round (they went round each loop on my layout about 5 times and a few of the fiddle yard storage loops, i coupled them with Blue Ribband MK1s as well to see if still ran fine, which they did). I also only tested them on B4 bogies. I will try Commonwealth bogies and some wagons once I get more supplies!

I will still probably replace all my coaches with Blue Ribband ones eventually (as they get released in all the liveries i want, and as I save the money!), but these are a very useful and very easy solution to shorten up the gap in the old coaches.
 
I will now send Russ a message to order more couplers!   I'm sure he can let you all know how to order them from him and the cost if you are interested.

N.B. Russ makes them in different lengths. 1.25mm, 1.5mm, 2mm.  They are transparent / off white plastic. You could paint them black / grey if you prefer that.

I prefer the transparent couplings - they seem more realistic!

I am surprised that they are all not made like this!!

ISTR that there is another supplier but ISTF their name!

I'm afraid I don't agree, I think the transparent ones actually look more hideous and noticable than the black ones! At least the black ones blend in a bit with the general buffer-beam/underframe :no:

Like the shortened gap between coaches though :thumbsup:

I like the close coupling idea but what radius is a radius 1,2,3 & 4 as I have limited radius on my layout?

Usually refers to Peco Setrack standard curves:-

R1 = 228mm (9")
R2 = 263.5mm (10+3/8")
R3 = 298.5mm (11+3/4")
R4 = 333.4mm (13.1")

:thumbsup:

Thanks Paul.

I need to test as I use a short shank on one end and a regular on the other in my EMU set ups..

Suppose I need to finish the track laying & wiring first though and not get side tracked...

yes sorry I meant peco radius 3 and 4

not sure if I like transparent or black couplings more, but easy to paint them if prefer black.

I am going to convert about 7 mk2s and 16 mk1s once more couplers arrive. intercity, regional railways and royal mail liveries not available in blue ribband mk1s so this is best option I think. not sure if will buy new mk2s yet as will be expensive.

I do the same with my 4CEP and it takes 9'' radius curves easily. I tried a short coupling on both vehicles but the gangways were too close and caused a derailment.

Definitely going to try these on the loco hauled stock. How do I get hold of them.
