This is a re-release of one of my older models. It's a Hawker-Siddeley cylindrical hopper that I originally built for Railworks 2. This download includes a set of standalone cars with custom sounds, updated shape files and textures.
Uninstallation of the old version is recommended before installing this new version, but probably not strictly necessary (I did not test this).
Older repaints should in theory remain unchanged when installing this new version. However, this too was not tested by me.
The GN and ATSF packs are freelanced with my HS model standing in for other manufacturers' cylindrical hoppers. Neither railroad company owned Hawker-Siddeley built cars in reality.
