how to stop troublesome wagons uncoupling?

i have a vba and a ferry van that are always uncoupling, no matter what wagons go either side of them...

any solutions to this? (i don't really want to glue them to other wagons...)

Hi Tim,

What kind of couplers are you using? Have you tried replacing the couplers on the offending wagons?

Fit knuckle couplers Tim, never had decoupling issues with them.

Also look at when they decouple, it could be a weighting problem with the wagons or sticking axles / wheelsets.

Whatever the reason I'd still fit knuckles, they look better too  ;)

Sometimes it can just be what height the couplings hang at and what angle/height they go to when pulled, so a little bit of bluetak can hold them in a better position.

Some people put retarders on the wheels to take up the slack.

If this is a Dapol Ferrywagon then it's a prblem with that - the couplers on them are low compared to other N gauge stock. I've not looked at rectifying this on mine as I usually run a fixed rake of all Ferrywagons so they are all low and match!

Cheers,
Alan

I  think we've all got a few temperamental wagons that always part ways at the drop of a hat.
Ok i've got a stretch of bumpy track and the board joints can be a bit of jolt too until I level the whole layout. (see my other threads)

I've just got hold of some stuff called tacky wax to stick pits of removable scenary down with, will try a dab of this on the inside face of the rapidos to see if this removes the unwanted uncouplings.

What are retarders?

There are several types, basically they just add drag to one or more axles. this is so that the whole train is under tension which should in thoery keep it all coupled
