TEAMING SWITCHERS AND MAINLINERS FOR ECONOMIC UNIT TRAIN HAULAGE

Railroads are economically transporting coal through the use of modern and efficient high capacity cars, high-horsepower mainline electric & diesel electric locomotives, and modern heavy-duty, diesel electric switchers. Each has a specific function to perform: the electric locomotive is on an automated railroad totally dedicated to loading, hauling and dumping unit trains; the mainline diesel locomotive is used in similar service but manually controlled; and the switcher locomotive's task is to load the cars while the mainline diesel is hauling the loads to the generating plant and returning again with empties. Investment in these efficient equipments and machines has proven to be the economical answer to low coal haulage cost today and promises to be the right answer for many years in the future. It remains for the coal companies, utilities, railroads, and equipment suppliers working together to optimize this transportation opportunity. Proper selection of the system and the equipment will make the system operate efficiently and at lowest cost. But, it must be kept in mind that the right answer for one mine/utility/railroad combination may not be the best answer for another. Each must analyze its own set of needs and conditions to achieve its right answer. The payoff for the analysis can be savings in the hundreds of thousands of dollars per year for all participants.
