鉄道 refers to the railway system used for transporting passengers and goods across various distances. It consists of tracks, trains, and stations, allowing for efficient travel and freight movement. Railways are an essential part of public transportation in many countries, providing a reliable alternative to road travel. The history of 鉄道 dates back to the early 19th century, with the first steam-powered trains revolutionizing travel. Today, modern 鉄道 systems include high-speed trains, subways, and light rail, connecting cities and regions while reducing traffic congestion and environmental impact.
