Slow trains still serving remote communities

People nowadays are usually impressed with China's high speed trains and rapid development. Older, slower trains, however, are still a lifeline for many rural residents.

China has built more high-speed train tracks than any other country in recent decades, amounting to over 29,000 kilometers as of the end of last year. That's more than two-thirds of the world's total.

Also, the country has been bidding goodbye to most of its old-fashioned trains known for their slow pace and drab interiors, without air conditioning or sleeper beds.
