Couplings
« on: January 20, 2020, 11:36:33 AM »
 :worried:
I'm fairly new to N Gauge. I've just bought a Graham Farish Open Wagon (373-630) to use with my Twin Dapol Box Vans (2F-025-002). It is regularly uncoupling. Although the couplers appear the same (Rapido type?), I'm not sure they're at the same exact height, and one seems to rise up and slip away from the other.
Is this a known problem?
Is there a solution?
Thanks, John Astin.

Hi John and welcome.

Well the couplers should be at the same heights, but as you can imagine small discrepancies can creep in sometimes with different manufacturers.  Regular uncoupling as you describe usually indicates there is a problem with one of the couplings being too low/high/loose so check them carefully.

Sometimes if I get a particular pair of wagons misbehaving together I try turning one of them 180 degrees or moving it somewhere else in the train.

Some folk find a tiny drop of CopyDex or Tacky-Wax on the inside faces of the couplings can help.

Many thanks for your swift reply. The other end of the GF wagon never uncouples from the GF loco, but I'll try turning it.
If not, I'll try Copydex or Tacky Wax as you suggest.

I have two types of train, John. One sort is fixed rakes using Rapido couplings and to overcome uncoupling on my 9" radius slopes I use a little scenic glue on each coupling.  The shuntable rakes are fitted with EasiShunts so that pick-up goods are possible.
Perhaps the proof that there is intelligent life in outer space is that they haven't contacted us.

Many of us have random uncoupling (railway wise, I hasten to add!) and I've found Peco wagons susceptible. Tacky Wax is my preferred solution

Problem I have is with C Rail KQA pocket wagons. Couplings appear to be drooping. Fine when coupled to each other but uncouple when coupled to a loco be it GF or Dapol.

Thanks to everyone who responded to my Couplings questions.
In this case, Tacky Wax - a new product to me - seems to have done the trick. It looks a useful product also for placing people on platforms etc. Good news. John Astin.
