This model is a Family Lines System reskin of the 50ft Boxcar included in the payware DTG PRR FA-1 Loco Add-On pack. I apologize for the static numbering, but the dynamic number-ing is in the wrong place. You can download the payware model here:

Run the RW_AssetSetup file to install the model. Copy the GEOPCX file from Assets\DTM\ ALCo FA1-PRR\RailVehicles\Freight\X50 Boxcar and paste it into Assets\DTM\ALCo FA1-PRR\RailVehicles\Freight\FLS Boxcar. In the scenario editor the model is listed as: “SCL 50ft Boxcar”. This model is installed into: Assets\DTM\ALCo FA1-PRR\RailVehicles\Freight\FLS Boxcar.
This package is released as freeware. You can do whatever you wish with it EXCEPT make money with its use.
