Assume a 220 ton engine is pulling 18 cars that weigh 110 tons each at 55 mph for 2000 miles. The average rolling resistance coefficient is 0.005 for the train. The diesel locomotive is 34% efficient in converting the energy in the diesel fuel into useful energy to power the train. Neglect aerodynamic drag. How much horsepower is required to pull the train at 55 mph? How much fuel is required to make the 2000 mile journey?
