 What purpose does wrapping wire around the axle have? I just recieved this wagon and it had wire on the axle of the wheels. Never saw this before. |

I’m guessing the wheels are isolated. A dc set. And the wire is connecting them and basically making them able to conduct current, making them an ac set able to trigger contact tracks. Just my guess.

Would this be to add some weight to the wagon.

Looks like someone lost their Spaghetti, I think there are better methods to add weight to a carriage. |

I have seen this in an old magazine from 1965. Supper idea.  |
I love the smell of smoke fluid in the morning . |

The other thing such 'weighting' would do is to add drag to the wheels so they not so free rolling. maybe the original owner had problems with his train rolling away after uncoupling on a slight slope. But, yeah, weird ...

I don’t think so Alan. If the weight is added in the wagon itself it would result in increased friction in the bearings and therefore increased rolling resistance, but when added around the axle it it increases the mass without loading the bearings. When the wagon moves the wheels roll over the rails not slide, so any change as a result of weight on the axle would be negligible.

But the solder would around the axle would create some drag on the axle. On your photo it looks like one end of the solder is poked into a hole in the chassis, so it won't rotate with the axle. I may be wrong, but that is what it looked like to me.

Maybe GaryTrooper can report back if the wire is rotating with the wheels or if it's stuck?
I have sometimes struggled with adding weight to cars so new tricks and tips are always welcome.
(Even though I've found that adjusting wheel spacing is often more important than adjusting weight).

I did that 50 years ago and on wagons with plastic wheels. It is desirable if you need to add weight to a light wagon that it is as low as possible and another plus is that by turning the heavier axles you get the effect of a flywheel!
