经对中国铁路隧道的运营、在建及规划情况进行统计分析，截至2025年底，中国铁路运营里程达到16.5万km，投入运营的铁路隧道共19 438座，总长约25 242 km； 在建铁路隧道共2 663座，总长约7 117 km； 规划铁路隧道共5 426座，总长约13 560 km。中国高速铁路运营里程超5.04万km，投入运营的高速铁路隧道共5 301座，总长约9 148 km。中国建成运营的特长铁路隧道共318座，总长约4 284 km； 在建特长铁路隧道共172座，总长约2 635 km； 规划特长铁路隧道共250座，总长约3 532 km。对在建及运营的特长铁路隧道，按7大地理区域分布情况进行统计分析。最后针对“十四五”期间铁路隧道建设的主要成就进行总结。

According to the statistical analysis conducted on China′s railway tunnels in operation, under construction, and in planning by the end of 2025, China′s operating railway mileage (route-km) reached 165 000 km. A total of 19 438 railway tunnels were in service (~25 242 km), 2 663 under construction (~7 117 km), and 5 426 in planning (~13 560 km). More than 50 400 km of high-speed railway (HSR) was in service in China, with 5 301 operating HSR tunnels, totaling ~9 148 km. Among them, the extra-long railway tunnels included 318 tunnels in service (~4 284 km), 172 tunnels under construction (~2 635 km), and 250 tunnels in planning (~3 532 km). Statistical analysis is conducted on the distribution of under-construction and in-service extra-long railway tunnels across China′s seven geographic regions. A summarization of the major achievements in railway tunnels during the 14th Five-Year Plan period is finally provided.
