HGV (High-speed rail)

High-speed rail (HGV) refers to a network of trains designed for rapid travel between cities, typically reaching speeds of 250 km/h (about 155 mph) or more. These trains run on specially constructed tracks with smooth, straight routes to minimize delays. HGV offers a faster, more sustainable alternative to car and air travel for medium to long distances, reducing congestion and emissions. They often operate in dedicated corridors, providing reliable, comfortable transportation, and are integrated into regional transit systems to enhance connectivity and economic growth.
