1, interval scheduling is difficult.
For a period of time, passengers are relatively concentrated and crowded, so it is difficult for passengers to get on the bus at the station, so this may lead to the delay of passenger train departure; With a large number of passengers running, the railway transportation capacity is in a state of supersaturation, and the difficulty of train operation adjustment is obviously increased.
2. The sudden increase of traffic flow.
The operation of the railway is strictly in accordance with the operation chart, which stipulates the stop time between stations, but the sudden increase of passenger flow will inevitably increase the boarding time, which will lead to delays.
3, railway equipment failure
For example, the speed limit of the line caused by the construction of the line along the railway, accidents and equipment failures, the damage of the line switch caused by the locomotive failure and the operation error of the traction train, etc. Fourth, weather and geological reasons, such as bad weather, heavy rain, heavy snow, fog, road collapse, etc., cause line restrictions and speed limits.
Relevant regulations on train delay:
The newly revised "Quality Standard for Railway Passenger Transport Service" by the Ministry of Railways stipulates that the train must be notified in time if it is late, and the reason for the delay should be explained and an apology should be made if it exceeds 30 minutes. ?
The standard requires safe and orderly ticket purchase, waiting, entering and leaving the station. The entrance security channel is clear, and the daily waiting time is no more than 5 minutes. Railways provide a variety of ticket purchasing channels and payment methods, and open and fair ticket sales.
Open a sufficient number of ticket sales windows, and the number of people queuing for tickets every day shall not exceed 20. The window division of labor, working hours and other written signs are clear, the ticket price is accurate when selling tickets and refunding tickets, and reimbursement vouchers are provided to passengers when refunding tickets.
The standard also requires the station environment to be clean, the air in the waiting room is fresh, there is free drinking water, and the toilet has no odor. The waiting room temperature is 18℃~20℃ in winter and 26℃~28℃ in summer.
