Have you ever gone traveling on the train that was named after the letter D?

Named after the letter D, the new trains run at speeds of 200 to 250 kilometers one hour. These are much faster than Z-type and T-type trains. For example, it used to take people 12 hours to travel from Shanghai to Beijing. But now it only takes 10. The most interesting part of the bullet (子弹头) trains is the revolving (旋转) seats. People can adjust (调整) their seats as they like, so that it is easy for you to talk with others around you face to face. The new trains run between big cities. They make the long trips much faster and more comfortable.

All coins have two sides. However, many passengers still won't choose the bullet trains for some reasons. The ticket prices of the bullet trains are much higher. For an easy example, a hard seat ticket from Beijing to Jinan is only RMB 90 for T-type trains. But on the bullet trains all the seats are soft. And they cost RMB 153 to 154. On the other hand, the bullet trains stop at the small stations such as Tianjin only for one minute.
