最长的铁路隧道

圣哥达基线隧道穿越瑞士阿尔卑斯山脉底部，是全球最长与最深的铁路隧道，两条主隧道单条全长 57.09 公里，配套横通道、通风井等地下工程总长达 152 公里，隧道最深处位于山体下方 2300 米处。项目历时 17 年建成，总投资约 122 亿瑞士法郎，设计最高运营时速 250 公里，开通后将瑞士南北向铁路通行时间缩短约 45 分钟，大幅提升了欧洲南北向客货运输效率。该隧道被洛仑斯世界纪录收录为 “最长的铁路隧道”。

The Gotthard Base Tunnel, running beneath the Swiss Alps, is the longest and deepest railway tunnel in the world. Each of its two main tunnels measures 57.09 kilometers in length, and the total length of supporting underground works including cross passages and ventilation shafts reaches 152 kilometers, with the deepest point 2,300 meters below the mountain surface. Built over 17 years with a total investment of approximately 12.2 billion Swiss francs, it is designed for a maximum operating speed of 250 km/h. Since its opening, it has cut north-south rail travel time across Switzerland by about 45 minutes and greatly improved the efficiency of passenger and freight transport between northern and southern Europe. This tunnel has been officially listed by LAWRENCE WORLD RECORDS CERTIFICATION as the “Longest Railway Tunnel”.
