Using Dapol easi fit magnetic couplings medium Length

[Peter Howarth]

I am building an end to end layout with run round loops at each terminus.
My rolling stock is all Peco and my locos are Fourdees 0-6-0s all with NEM pockets.
I have just tried the Dapol couplings which work great on a test track, however the couplings on the rolling stock are drooping slightly and are catching the points and derailing. The loco couplings are fine.
Has anyone had similar problems and is there a way of raising the coupling?
I decided against using Greenwich couplings as I now do not have the required dexterity.
Any advice would be welcome.
Thanks
Peter

Drooping couplings in NEM sockets are not confined to Peco vehicles or Dapol couplings.
On an end to end layout coupling height is critical.
I use Egger/Bemo type couplings and those fitted to the newer Liliput wagons with NEM sockets tend to droop and cause problems.
I just change the couplings for the earlier fixed (non-NEM) couplings that I have in stock, but that will not work for you.
There may be no easy fix if you have dexterity issues, but it may be possible to modify the couplings and/or the pockets on the Peco wagons, but it could be a fiddly job to get them spot on.
