What reforms have my country’s railways made to adapt to the tourism situation?

Railway transportation is the main mode of tourism transportation in my country. Since the 1990s, my country's railways have carried out a series of reforms and developments in order to adapt to the needs of the tourism situation and market economy development. The speed of trains has been increased many times, speeding up the operation of trains; railway double tracks have been built, electrification has been carried out, and various tourist trains have been opened. Especially in recent years, the great development of high-speed railways has not only increased the speed of trains, but also made the equipment in the carriages more complete, comfortable and clean, greatly meeting the needs of tourists. By the end of 2015, the country's total railway mileage was 12x104km, ranking second in the world, forming a dense spider-web-like railway transportation system centered on Beijing and composed of "five vertical and three horizontal" trunk lines.
