For the first time in four decades of dieselization, railroads are encountering real fuel difficulties. As an answer to that problem, electrification has been investigated by quite a few railroads, and soon, the world's first 50,000-volt alternating current electric locomotive will be ready to operate on the continent's newest electrified line in Northeastern Arizona. The 50-kv commercial-frequency AC system, which is being pioneered by GE, could well be a prototype for the system that would be applied to western lines. In the east, railroads would probably be electrified with 25-kv. The new 50-kv technology makes possible fewer substations and utilizes thyristor-controlled electric locomotives. The solid-state control and rectification equipment makes possible high-capacity freight locomotives. The 50-kv also involves a low cost catenary system.
