At times I feel they are not fit for purpose when it comes to British Outline wagons.
The wagons are too easily drawn along out of an uncoupling position by 'magnetic creep'
Many of us have spent ages getting our stock to run VERY freely with thoughts of long goods
trains. This is the path to absolute failure, mass has little influence, the pressure needed to open
the knuckles is not reached before your wagon rolls along !!
Well the only answer to my mind is adding brakes to one axle on every wagon intended to be run
on a layout that relies on Kadees for a slick hands free session. Yes, I've now developed two sets
of wagons that are dedicated to particular layouts. They can interchange as this video shows.
You will need to do a Kadee shuffle quite often as when a wagon has disengaged it will be sitting
over the magnet which will pull the knuckles into a 'free shunting' mode where they will not re-couple.
To re-connect it's necessary to push the wagon off the magnetic zone, draw away to allow the knuckle
to return to the normal position for coupling.
I 'aint no expert and believe me the language has been ripe at times, but this video shows what can be
achieved with wagons. Note NO comments about coaches as these do not usually suffer magnet creep.
Also a train of just two coaches creates enough resistance to couple up as wanted. ..... Usually !!
