Transportation networks have experienced major growth and expansion since 1949 and especially since the early 1980s.
Railroads, which are the primary mode of transportation, have doubled in length since the mid-twentieth century, and an extensive network provides sufficient service to the entire nation.
Even Tibet with its remote location and seemingly insurmountable terrain has newly opened railroad service. The larger cities have subway systems in operation, under construction, or in the planning stage.
The highway and road system also has gone through rapid expansion, resulting in a rapid increase of motor vehicle use throughout China.
