China still has tons of slow trains and they are dirt cheap , but most people will choose HSR if they can afford it . The US essentially doesn ' t have a rail network outside of the East Coast . It is extremely expensive to build , but that hasn ' t stopped China from building the network using government funds . It ' s not a for profit system any more than the interstate highways are in the US . That being said , the idea is that the economic development resulting from the rail lines outweighs the initial costs . In China , that growth has been very large , particularly in hightech and finance sectors . There are 100 trains between Guangzhou and Shenzhen daily for example , and this has led to the two cities becoming integrated in business .
