The Union Pacific rarely assigns manned helpers to shove trains from Ogden to Wahsatch on the Evanston Sub. On February 16, 2013 an SD40-2/SD70M combo team up to push a 188 car West Colton, CA to North Platte, NE freight east through Echo Canyon at Emory. The MWCNP 14 has two motors on the point and a single DPU placed 125 cars behind the head end power. Now THAT my friends is a drag freight!
Coal and steel don't go bad. This album features long, slow, heavy freight trains; drag freights, slop freights, dead freights, etc. Trains with lots of power, and lots of different cargo slogging along behind.
