The hostler has readied the power for the 11-Empire (11 PM run to Empire Mine) on a cold winter's night. The former BN U30C and C30-7 still wear their white heralds and numbers. But what matters tonight is not the logo, but the cab heater and the horses; 4000 tons of iron ore doesn't move itself. The crew is anxious to get going, because the sooner the job gets done, the sooner they can return to their warm homes. Now if only the dispatcher would give permission to depart.
