Abstract :
Some rail operators discourage their drivers from using maximum power on the grounds that it has high fuel flow rates or high energy consumption rates. However, optimal control theory indicates that the most efficient driving strategies should use maximum power. Although the rate of energy use is higher while using maximum power, the duration of power phases is shorter and overall energy use is less. We use realistic examples to show how using more power when accelerating can reduce overall energy use.
