Do You Recognize This Wagon?

[Super]

This question didn't fit the Trackmaster or the Plarail Forum since this wagon was made by the HiT Toy Company.

There are lots of these tipping carts in various colors but I haven't seen very much of these dark grey ones. Anyone recognize this dark grey one and maybe know what set it was included in or if not a set, what train it may have come with? I am not having any luck in my search.
