Iowa Interstate Railroad has embarked on an 8-month test of biodiesel use in a locomotive at its Council Bluffs facility. The engine’s performance is being analyzed to determine the effects of biodiesel fuel on horsepower, fuel economy and engine wear. The tests will continue into the winter to determine cold weather performance. According to CEO Dennis Miller, positive results could “open the door for more than 600 railroads to add biodiesel as a fuel source.”
