This single engine on the front of a unit coal train here on the Colorado Joint Line is a little unusual. While there’s no actual ‘formula’ for consists on unit coal trains, the typical set up is two engines in the front, 100-120 hoppers, and two engines bringing up the rear.
When this single leading locomotive first appeared, it looked a little weird. But this trio of EMD SD70ACes seemed like a good capture… after about an hour of waiting.
