China Trains

Yes, of course. Right now the country puts a lot of money into improving the existing railway system and expanding its high-speed network, and it wouldn't have been done if this project had no potential to bring even bigger profit. The Chinese railway system is not only the biggest network but also the most extensively used one, so train travel in China is going to have a very bright future. 

"Progress" and "China" are pretty much synonyms, but what they did with the railway system during recent years is almost a miracle. Only in 2018 alone, the country built over 4 100 km (2 548 mi) of high-speed railways and raised the total length to 29 000 km (18 000 mi). By February 2020, the country plans to have over 36 000 km (22 350 mi) of high-speed railway in operation. 

You can either get your tickets at the station before departure or book them online in advance, an option that saves a lot of time and allows avoiding the unpleasant surprise of already sold-out tickets. If you decide to purchase your tickets with Rail Ninja, you can not only do it in several minutes but also book them for up to 2 years before your trip.
