This is what they look like.

And the adhesive is very tenacious.  I've used them in a Weaver hopper that was light as a feather.

I'll ask a beginner question - why add weight? Is it for realism in approximating a load? Or to help the cars stay on the tracks while navigating curves, switches, coupling up, etc?

The cars are too light to stay on the track reliably, especially if they're located ahead of heavier cars.
