This simple, subtle open freight wagon can be used in all sorts of scenarios and works for both a mixed freight train as well as a full consist of only these wagons. It can also be mixed inbetween some of the open freight wagon for sugar beets, making for a more interesting train overall.
Please be aware that the height of the buffer is 2 plates above the standard height for a more realistic appearance, therefor the magnet is higher as well. Getting the buffer piece to be lower will need a bit of modificiation but should not be difficult. The minimum radius might be smaller than R104 but that was not tested by me.
