Internal User Series
Internal User vehicles are those that are not allowed to run on the mainline, but are only for use within depot complexes. They are often stationary, though not always. Two former locomotives that were heavily stripped, leaving just the frames, to carry power units within Toton depot were allocated IU numbers.
