Core Viewpoint - The article discusses the evolving role of traditional slow trains (referred to as "green trains") in China's railway system, highlighting their continued importance despite the rapid expansion of high-speed rail networks. It emphasizes that these trains serve essential functions for specific demographics and regions, providing affordable transportation options. Group 1: Train Operations and Statistics - As of January 26, the new train operation schedule includes a total of 12,130 scheduled passenger trains, with many conventional trains being reclassified from Z, T, and K to D for high-speed trains [2] - On January 27, 2026, a total of 1,225 trains were scheduled to operate, including 162 direct trains (Z), 132 express trains (T), 680 fast trains (K), and 251 pure number trains [6] - The maximum speeds for different train types are as follows: Z trains at 160 km/h, T trains at 140 km/h, K trains at 120 km/h, and conventional trains ranging from 80 km/h to 120 km/h [7] Group 2: Role and Value of Green Trains - Green trains connect cities with populations over 200,000 and resource-rich areas, serving as a vital link for low-income groups and residents in remote areas [3][4] - The affordability of green trains is a significant draw, often costing half or less than high-speed train tickets, making them a preferred choice for budget-conscious travelers [10] - In remote areas, green trains are crucial for local communities, providing essential transport services and even acting as mobile libraries for students [11] Group 3: Economic and Social Impact - Green trains have lower construction costs and can effectively connect surrounding regions, promoting local economic development, especially in smaller cities [12] - From a freight perspective, green trains are more economical, with railway freight costs being about one-third of road freight costs, and they have a significantly lower environmental impact [13] - Despite their ongoing utility, the overall number of conventional trains is decreasing, with a reduction of 71 trains compared to the previous schedule [13]

1月26日起，全国铁路将实施新版列车运行图。调图后，全国铁路安排图定旅客列车开行总数达12130 列，其中多趟普速列车(俗称"绿皮车")将更换车次标识，由原Z(直达)、T(特快)、K(快速)字头升级为D 字头动车组列车运行。 可以说，我们的铁路越来越快了，全民进入一个快时代。 如今，中国高铁网络已突破5万公里，成为人们出行的主要选择。然而，在追求速度与效率的时代，橄 榄绿色的普速列车依然沿着许多线路稳定运行，是中国铁路系统不可或缺的一部分。这一现象令人思 考：当高铁已成为交通出行的主流，为何这些速度较慢、设施相对陈旧的列车仍然被保留并持续运行？ 绿皮车与高铁并非简单的替代关系。中国物流学会特约研究员解筱文在接受经济观察报采访时表示，根 据《新时代交通强国铁路先行规划纲要》，普速铁路与高速铁路在路网功能和服务定位上各有侧重。 普速列车主要连接20万人口以上城市、资源富集区、货物集散地等重要节点，基本覆盖县级以上行政 区，并兼顾货物运输功能。其服务对象包括偏远地区居民、中低收入群体等，为他们提供经济普惠的出 行选择。而高速列车则是要实现省会城市及50万人口以上城市高铁通达，构建全国主要城市间1、2、3 小时高铁交 ...
