I think this is going to take a long time to be actually be deployed for public use. China's top transportation plans is signaling its taking a more conservative approach to hard infrastructure development in the next 10 years. It is balancing debt and cost. It calls for more local transportation between cities and their satellite cities/towns. These are slower and cheaper to build. It calls for more stringent review of 350km/h HSR lines. In the past, local governments have been rampant in building 350km/h HSR lines, even if the projected ridership is low. These lines cost a lot more to build and operate than lower speed HSR or regular lines, and cannot be used for freight. China currently lacks freight train capacity, and freight is more profitable and its revenue outlook continues to grow. The planning document calls for more commuter and freight duo use lines for middle and western part of the country.
