First, trains without letters are generally green leather cars. With the transformation of electrified lines in China, the most primitive green leather cars are gradually eliminated, but they will still be used on some short-term roads. There are many small stations, and sometimes you have to make way for other cars and stop halfway. The running speed is 80 to 100KM/H, such as1125/1128 Luoyang-Guangzhou train.
