What is this one from again?

[Super]

Those are neat coal cars. I am not exactly sure and I know we discussed them before but for some reason the light in my head says they were in one of those Fisher Price 3 Packs of freight cars but don't quote what I see in my head. I do know that for some reason they decided to glue the blue shells to the black chassis when they already held it together with a screw. It took some finagling and time to persuade them apart so I could swap out the white couplers with black.
