Hopefully a simple question - what are these couplings called?

They are on a few Farish Mk1 coaches that I bought online without checking the pictures closely enough and so I will probably look to sell on but wanted to be clear in my descriptions as to what they are. From what I can see they are knuckle couplings but are there different sub-types, or would that be a sufficient description when selling?

Thanks in advance for the group advice 

Look like Kaydees to me

I believe nowadays KayDee tends to refer to the HO buckeyes, whereas the N scale version are Microtrains.     Similar to (but not identical) to other buckeyes such as Bachmanns, Kato, Dapol Easy-Shunt.  That example does look like a Microtrains.

Should be easy enough to replace with a standard Rapido T-shank coupling and spring, readily available from Graham Farish.   Post a clear photo of the underside of the bogie to confirm the type of coupling pocket fitted?

Thanks for the info.

This is the underside of one of them - and does look like the original coupling was removed and a new small pocket fitted inside. It does seem to be tightly wedged in (which I guess it has to be to stop it coming out) and just hoping it hasn't been held in with glue. I have tried to gently push it out but it isn't moving. I guess just use more force and cross fingers?

OK so that is a T-shank pocket on the bogie.  You could try twisting the coupling 90 degrees to see if the shaft will then pull forward out of the front of the pocket.

You'll need T-shank Rapido couplings and springs to fit in place of the buckeyes.  It's a simple job.

Hi

To remove the draft pocket (piece where the t shank fits) you need to press down on the top of it probably with the bogie removed.

This then releases the t shank of the Microtains coupling. Be careful not to lose the very tiny spring. The actual coupling can then be rotated through 90 degrees to remove.

This may help

Thanks Everyone

Managed to pop out the coupling (having taken the bogie off of the coach to make access easier) - fortunately there didn't seem to have been any glue used, just a tight squeeze. Just had to take the plunge and press with some pressure! I can now fit standard couplings and use the coaches.
