Before the 2026 Spring Festival travel rush, a technical team spent one and a half months conducting repeated simulations, optimization and debugging, advancing the departure timing by one step. A breakthrough of just 2 seconds has led to a significant increase in transport capacity, enabling an additional 48 train arrivals and departures per day and transporting more than 30,000 additional passengers. During the 2026 Spring Festival travel rush, the peak daily number of operating trains at Guangzhounan Railway Station can reach up to 1,300, an increase of 97 trains year on year.
