MORE CARS ARE AVAILABLE!
Have you ever noticed that the default Hopper car in RRT3, which gets used to carry bauxite, coal, and iron, has a stencil on the side which clearly forbids such loads? "Ballast Loading Only" it says, or something to that effect. Isn't that irritating?
Well, the remedy is here!

Three new cars, one each for bauxite, coal, and iron, for you to download and install. These cars have some extra transitional models introduced, so that your train sets evolve more gradually. And of course, they are based on authentic North American prototypes, at least as far as possible. As a die-hard Norfolk & Western fan, I've made all the coal hoppers to resemble N&W cars, but the other cars represent a variety of roads.
I've got more to come later, so keep checking back to my site. I'll beg Hawk to host them here, as well; Hawk has yet to add the Passenger car sets to his page, but you can get that at my site too.
Enjoy!
