electricrail

Electricrail refers to a transportation system that uses electric locomotives or multiple units to pull or propel trains along a railway track. The electricity is typically supplied through an overhead catenary system or a third rail. This method of propulsion offers several advantages over steam or diesel engines, including reduced air pollution at the point of use and often lower operating costs due to the efficiency of electric motors. Electric rail systems are a common feature in urban commuter networks, high-speed rail lines, and some heavy freight operations.

The development of electric rail began in the late 19th century, with early experiments and commercial applications emerging around the 1880s. Early systems were often powered by direct current (DC) electricity. Over time, advancements in technology led to the widespread adoption of alternating current (AC) power, which allows for more efficient transmission of electricity over longer distances. Modern electric trains can achieve very high speeds, making them a cornerstone of intercity and international travel in many parts of the world. The infrastructure required, such as substations and power lines, represents a significant initial investment, but the operational benefits are substantial.
