Core Viewpoint - The phenomenon of "immediate waitlisting" for train tickets during peak travel times is not solely due to slow purchasing speed, but rather a result of limited ticket availability for specific routes [4][12][27]. Ticket Availability and Distribution - The ticketing system differentiates between full journey tickets and segment tickets, with the former generally having more availability [4][6]. - Historical data and demand forecasts are used to allocate tickets among different segments, leading to uneven distribution based on travel demand [8][14]. - For example, tickets from Beijing to Shanghai (full journey) are more plentiful compared to tickets for segments that only cover part of the journey [6][10]. Waitlisting Mechanism - The waitlisting system was introduced to better match passenger demand with available tickets, allowing for automatic ticket purchases when cancellations occur [15][17]. - This system aims to minimize opportunities for scalpers and ensure that tickets go to genuine travelers [15][19]. Seasonal Demand and Capacity - During peak travel seasons, such as holidays, the demand for tickets can exceed supply significantly, leading to intense competition among travelers [25][26]. - For instance, during the 2025 Spring Festival, the railway system is expected to handle over 5.13 billion passenger trips, with certain regions experiencing disproportionately high demand [26][27]. Conclusion on Ticket Purchasing Strategy - To increase the chances of securing tickets, travelers are advised to opt for full journey tickets whenever possible, as they provide access to a larger pool of available seats [27].
