After bringing up limestone from Proctor to the Minntac plant, CN 2039 backhauls a 50-car train of crushed taconite rock (blast furnace trim) as they head back to Proctor.
The southbound MRF rolls through Saginaw, bound for Proctor. A CN standard cab Dash 8, a CN SD60, a DMIR/CN tunnel motor and a CN GEVO provide the power for the short train.
