Hopper car for the transportation of bulk cargo. To protect against atmospheric precipitation, indoor hoppers with loading hatches on the roof are used. The model is presented in the logo of Seaboard System

nstallation:
To install, use IMGTool. Opening gta3.img with it (located in the 'models' folder in the game directory), use the FIND command to find and delete the freiflat.dff and freiflat.txd files and use the ADD command to paste the files from this archive.

It is also possible to install this car instead of the standard covered freibox car, after renaming the files freiflat.dff and freiflat.txd to freibox.dff and freibox.txd, respectively. By default, the freibox car does not appear in railway traffic; to display it correctly, it must be registered with the SA Train Limiter utility in one of the trains.
