This model is a Pennsylvania Railway black reskin of the H21a Hopper included in the Horseshoe Curve route produced by Dovetail Games. You must purchase and install the HSC route for this model to work.
Between 1911 and 1917 70 ton H21a "quad" hoppers were introduced for coal service. During 1922 and 1923 all early H21 hoppers were converted to H21a's by replacing the 50 ton trucks with 70 ton trucks equipping them for coal service and bringing the total to 36,000 H21a hopper cars. The original 1909 thru 1930 quad hoppers were built with the "old style" double door hopper. During the 1930's and early 1940's all old style double-door hoppers were replaced with the "saw tooth" hopper, increasing capacity by 39 to 40 cubic feet making them easier to maintain.
Run the RW_AssetSetup file to install the models. In the scenario editor it is listed as: “HSC Hopper H21a Black.” In order for this model to work properly, you must go to Assets\RSC\HorseshoeCurve\RailVehicles\Freight\Hopper_H21a\Default and copy the GeoPcDx file. Paste the Geo file into Assets\RSC\HorseshoeCurve\RailVehicles\ Freight\Hopper_H21a\Black.
This package is released as freeware. You can do whatever you wish with it EXCEPT make money with its use.
