上述线路的全线贯通，是"十四五"以来广西铁路建设实现历史性跨越的生动缩影。五年来，广西铁路网 持续加密、扩容、提质，开工建设黄桶至百色铁路、合浦至湛江铁路等7个项目，建成贵阳至南宁高 铁、南珠高铁南宁至玉林段等8个项目。 在钢铁动脉织密成网的同时，广西高铁的运行标准也实现了同步飞跃。早期广西境内高铁线路运行时速 主要为250公里，"十四五"期间建成通车的贵阳至南宁高铁将设计时速提升至350公里，标志着广西高铁 网络正式迈入350公里时速时代。如今，乘客早上在贵阳吃肠旺面，中午即可在南宁打卡老友粉的便捷 生活已成为现实。 一系列具有里程碑意义的项目相继通车，从不同维度构筑起广西高铁新格局。在速度标准上，贵南高铁 作为首条设计时速350公里的线路，开启了"快车道"新篇章。在路网覆盖上，南珠高铁南玉段正式开通 运营，标志着广西14个设区市全部实现"市市通高铁"，成为中国西部地区、全国少数民族自治区中首个 实现"市市通高铁"的省份。在国际联通上，防东铁路与南凭高铁先后建成，形成对接东盟新的钢铁大动 脉，有力支持边疆民族地区高质量发展。 中新网南宁1月13日电 (杨陈 韦念 孙韦华)广西交通运输厅13日介绍，至"十四五 ...
