From 1876 to 1917, Northwest Railway operated the Bull Train on the 200 mile trip from Ft. Pierre to Deadwood, a journey that took 15 days. Twenty oxen pulled three wagons carrying 20,000 pounds of freight, or 1000 pounds for each ox. They traveled from 4 am until 10 am, then rested and grazed the oxen until 4 pm before continuing until dark. The complete Bull Train consisted of 30 wagons and 200 oxen, plus an extra 50 head used as replacements.
