China digs up coal in the west and then sends it east thousands of kilometers away. Every day on just one rail line there are 226 trains. Each train has 20,000 tons of coal. Each coal train is 2 miles long. This is moving about 4,500,000 tons of coal per day. This is 1.7 billion tons of coal per year on one rail line. China used about 3.8 billion tons of coal in 2018. There need to be 2 rail lines moving coal. There would need to be about 500 coal trains moving every day. There are probably fewer trains in that there is also trucking and barging of coal.
The coal train segment starts at about 19 minutes in this video.
