A Standard Gauge Railway refers to a railway system that uses a track width of 1,435 millimeters (4 feet 8.5 inches). This gauge is the most widely used globally, facilitating interoperability between different railway networks. It allows trains to travel smoothly and efficiently across various regions without the need for changing tracks. The adoption of standard gauge has played a significant role in the development of rail transport, influencing the design of trains and infrastructure. Many countries, including the United States and those in Europe, have implemented this gauge to enhance connectivity and improve transportation services, benefiting both passengers and freight movement.
