Wagon for transportation of bulk cargo. To protect against atmospheric precipitation, internal funnels with loading hatches on the roof are used. The model is presented in CSX Grain Express.
It is also possible to install this wagon instead of the standard "freibox", after renaming the files freiflat.dff and freiflat.txd to freibox.dff and freibox.txd, respectively. By default, the freibox car is not displayed in the rail message; it must be registered with the SA Train Limiter utility on one of the trains to be displayed correctly.
