The bullet train D106 from Changsha to Shanghai has a short stop in Quzhou for only one minute．

Named after the letter D, the new trains run at speeds of 200 to 250 kilometers one hour．This is much faster than Z—type and T—type trains．For example, it used to take people l2 hours to travel from Shanghai to Beijing．But now it only takes l0 hours．The most interesting part of the bullet trains is the revolving(旋轉(zhuǎn))seats．People can adjust(調(diào)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 cites．They make the long trips much faster and more comfortable．

However, many passengers still won’t choose the bullet trains for some reasons．The ticket prices of the bullet trains are much higher．For example, a hard seat ticket from Beijing to Jinan is only 90 yuan for T—type trains．But on the bullet trains all the seats are soft．And they cost 153 to184 yuan．On the other hand, the bullet trains don’t stop at small stations．
