Are you confused with the title? as we know, the subway trains run on a dedicate line, they never encounter a traffic jam unless there is an accident or there is an error with the signal system.
Actually everything goes well this morning, but there are TOO MANY people in the HuoYing subway station, it was already 8:30 when I arrived at the subway station, a large troop of people go along the narrow zigzag passageway to get in the station. the subway company use some barriers to limit the passenger flow during the peak period, the peak time last thirty minutes commonly, from 7:30 to 8:00, but today, the passenger flow is still very high till 8:30.
There are more and more people take the subway to go to work since the ticket price reduce to 2 Yuan in last Oct. Yes, you only need to pay 2 Yuan for taking the subway once, wherever you want to go. For this reason the passenger flow volume was doubled since last year. The good news is subway company is planning to add two additonal carriages for each train run on Line 13. it is said this project will complete at the end of this year.
