Have you ever taken a high-speed train with a four-digit number starting with 4 or 9?

During the Spring Festival travel rush, we often hear

News reports on "additional trains"

In the already dense train schedule

How to “take advantage of every opportunity”

Let more passengers buy train tickets

There is a mysterious team behind this

They are called

The "actuary" who optimizes train operations

As soon as the Spring Festival holiday ends, the passenger flow at the station will increase significantly.

Most of the additional EMUs have four-digit train numbers starting with 4 or 9, for example, G9691 and G4591 are temporary trains.

In order to maximize the travel needs of passengers, a group of staff are specifically responsible for monitoring train ticket sales and making train allocation suggestions. They are the "actuaries" of the railway system.

Of course, adding more trains cannot be a wild idea. It is the result of sufficient market research, clear overall planning, and precise comprehensive cost and capacity calculations.

During the Spring Festival travel rush every year, the workload of the station planning office increases exponentially. From adding a train to a passenger seat, the "actuaries" have to take care of everything. If there is a change in the model, they have to rush to the platform to check the train number and model information in advance to ensure that the information is correct. They work hard to "decode" the direction of passenger flow, continuously optimize train routes, and implement the "one map per day" plan to provide convenience for passengers.
