High-speed rail (HSR) networks are revolutionizing long-distance travel. With trains capable of reaching speeds over 300 km/h (186 mph), HSR offers a faster and more comfortable alternative to air travel for distances up to 1,000 km (620 miles). HSR systems connect major cities, reducing travel times and boosting regional economies. As countries invest in expanding their HSR networks, this mode of transportation is set to play a significant role in the future of intercity travel.
