Steam dominated the rails for a century, but the promise of improved efficiencies through the use of internal combustion engines encouraged builders to experiment with the technology. Early designs often involved gasoline or kerosene-powered engines, but diesel ultimately became the favored fuel. Most locomotives use the diesel engine or “prime-mover” to drive an electrical generator which then powers electric traction motors that turn the axles. This configuration is called a diesel-electric locomotive and it is the most common type in the United States; however, numerous other designs exist as well. Diesel locomotives were widely adopted after World War II and can be seen at the front of most trains in the United States today.
