What's great about them is that it works with magnetraction engines, when I put my
EP-5 on the tracks it really sticks, with the atlas it's a no go no stick. I just wanted
to get some track that would work great with my Hudson and my other engines and
I got it at a great price.

The Atlas O 21st Century nickel-silver track won't work with Magnetraction for sure, although their steel track will.
Nickel-silver is a non-ferrous material, which means it has very low to virtually non-existant traces of iron in it, and that's what makes it non-magnetic. The upside to nickel-silver is that it's much more corrosion-resistant than regular steel. Instead of rusting like steel, the surface actually oxidizes, and that oxidization remains electrically conductive.
