This simple open freight wagon was mostly used in long consists to move harvested sugar beets. The model is build approx. in 1:45 scale and uses no custom pieces.
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.
