Adding Weight

[jerryl]

I have some wooden & resin box cars that I purchased, that are underweight.There is no way to take them apart & was wondering if you know of a way to add weight. In the past I tried adding buckshot & white glue with not much success. Any bright ideas. Thanks. Jerry

Assuming you don't have a bunch of truss rods in the way, flat lead fishing weights held in place with super glue should do the trick
