1st Radius Curves

[Lofty]

Are… wagons prone to falling off the tracks?

I have a test circle that is even tighter than first radius, I find that more often than not it is the couplings binding that forces wagons to take a hike.

Hi Kebang,

As Dave-00 says couplings can be a cause, particularly if the hooks get
onto the wrong side, overlapping rather than being parallel.
In addition Dapol wagon wheels are not the best. I use them frequently
with no trouble, but they have small flanges, so short that they easily
lift above the track rail head and then just fall off !!
I keep a bag of wheels and when something is troublesome I exchange
the axles with Hornby 3 hole wagon wheels. The Hornby flange is much
deeper and makes allowances for uneven track and direction changes
like pointwork.

I think the problem must be wheels as I had no problem with the couplings on the Genesis coaches, and they are very small. Fortunately I ten Hornby axles arrived with my order so I will try swapping them over

Thanks Bigmet,
I've replaced the wheels on the Dapol Wagons with Hornby wheel/axles R8098 and the 3 wagons are behaving well now, being pushed and pulled continuously for hours around my test oval.

Is a case where ultra scale wheels and track etc is not such a good idea with our models even if one has very large radius curves, as the way gravity and other forces act on smaller scale items is different to how they act on the real railways, so a compromise is needed in order to make things work. (Also the weight of our models is in different places etc.).
