Group 1 - The naming rules for train numbers are closely related to the running directions of "up" and "down" [2] - Trains heading towards Beijing are classified as "up" and assigned even numbers, while those moving away from Beijing are classified as "down" and assigned odd numbers [2] - For example, a train from Zhengzhou East to Anyang East is an "up" train with the number G6666, while the return train from Anyang East to Zhengzhou East is a "down" train with the number G6665 [2] Group 2 - The letter prefix in train numbers has specific meanings, such as G for high-speed trains, C for intercity trains, D for动车组 trains, Z for direct express trains, T for express trains, and K for fast trains [3] - The numbering system allows dispatchers to quickly identify the type, grade, and task of any train operating on the line [2]

Group 1 - The naming rules for train numbers are significant, with specific letters indicating different types of trains, such as G for high-speed trains, C for intercity trains, D for动车组 trains, Z for direct express trains, T for express trains, and K for fast trains [1] - Train number assignment is closely related to the direction of travel, with even numbers assigned to trains heading towards Beijing (upward direction) and odd numbers for those traveling away from Beijing (downward direction) [3]

Core Insights - The fundamental contradiction between speed, demand, and safety in high-speed rail operations needs to be addressed to enhance service efficiency and safety [1][2]. Group 1: Speed and Demand Management - The China Academy of Railway Sciences has developed a new generation of high-speed trains capable of trial speeds of 450 km/h and operational speeds of 400 km/h, which shortens braking distances while ensuring safety [2]. - Increasing train density through optimized schedules and train configurations, such as doubling the number of carriages during peak times, significantly enhances transport capacity [2]. - Multi-dimensional regulatory measures can balance rising passenger demand across different times, regions, and speed levels, including differentiated pricing strategies [3]. Group 2: Automation and Safety - The implementation of automatic driving technology in high-speed trains, such as the Beijing-Zhangjiakou high-speed railway, allows for automated operations with minimal human intervention, enhancing operational efficiency [3][4]. - The safety of high-speed train automation is emphasized, with future developments focusing on self-awareness of the train's environment, safety assessment, and fault diagnosis capabilities [3][4]. - The transition from traditional manual operations to a data-driven, intelligent collaborative system is essential for improving safety and efficiency in high-speed rail operations [4]. Group 3: Challenges and Innovations - Current challenges in high-speed train automation include environmental perception limitations, compatibility of human-machine collaboration, safety verification, and system integration complexities [4][5]. - Future intelligent high-speed trains are expected to feature smart power supply scheduling, automatic environmental monitoring, and disaster early warning systems, enhancing overall operational efficiency [5]. - The focus on safety remains paramount, with a shift from cost-based safety redundancies to proactive monitoring and intelligent fault tolerance systems [4][5].
