Is it an official China Railway propaganda thread?
What happened to 90 locomotives which China exported to Pakistan which never worked, three years back? Did China made a third rate machinery or Pakistanis did not know how to operate them.
Yes, China has a few showcase high speed rail lines, but all for propaganda purposes in the west. Chinese do not need a huge rail network because much of industry is close to the coast along South and North China Sea, hence other than coastal network, much of the hinterland has thinner rail network except for one I.e. rail line going north to south to Tibet. That has no commercial or even strategic value because it is built on permafrost. The latter is open to military interdiction and melting away in a conflict.
