Back in 2007, this Alma, WI, to Black Thunder Mine, pulls into the siding at Antelope on the Jamestown Sub. The leader is less than a year old, and is leading 2 older MACs. The Dickinson Sub is the old Northern Pacific route thru North Dakota between Mandan and Glendive, MT. Hard to believe trackage thru this area was built back in the 1880's.
