弥蒙高铁全线轨通

Mimeng High-Speed Rail Line

2022年1月19日弥勒-蒙自高速铁路的最后一对钢轨平稳就位，标志着由中铁三局承建的弥蒙铁路正线铺轨完成。

On January 19, 2022, the last pair of rails of the Maitreya-Mengzi high-speed railway was smoothly put into place, marking the completion of the track laying of the main line of the Mi-Meng Railway constructed by the China Railway Third Bureau.

新建弥勒至蒙自铁路位于云南省东南部，总体呈南北走向，正线长度106.826km，桥隧比45.26%，全线共设弥勒（既有）、竹园、朋普、开远南、红河等5个车站，其中弥勒为既有云桂线接轨站，其余均为新设中间车站。建成后将替代昆玉铁路和玉蒙铁路，接轨南昆客运专线昆明至弥勒段，成为连接云南省省会昆明、弥勒、开远以及红河州首府蒙自的重要客运通道。

The newly built Maitreya-Mengzi Railway is located in the southeastern part of Yunnan Province, with a north-south direction as a whole. The main line is 106.826km long, and the bridge-tunnel ratio is 45.26%. There are Maitreya (existing), Zhuyuan, Pengpu, Kaiyuannan, Honghe, etc. There are 5 stations, of which Maitreya is the existing Yungui Line connecting station, and the rest are new intermediate stations. After completion, it will replace the Kunming-Yujiang Railway and the Yumeng-Mongolian Railway and connect the Kunming to Maitreya section of the Nanning-Kunming Passenger Dedicated Line.

弥蒙铁路地处高原地带，长大坡道多，运输安全隐患大，尤其是全长近4公里的白沙坡隧道，30‰的连续下坡极具代表性。由于坡道大，连挂机车多，机车和铺轨机的尾气排放相应也多，在有限空间内会对呼吸系统造成很大影响，如果防护措施不到位，甚至可能造成窒息的风险。

The Mi-Mongolia Railway is located in the plateau area, with many long slopes and great hidden dangers to transportation safety. Especially the Baishapo Tunnel with a total length of nearly 4 kilometers has a continuous downhill of 30‰, which is very representative. Due to the large ramp and many locomotives, the exhaust emissions from locomotives and track-laying machines are correspondingly large, which will have a great impact on the respiratory system in a limited space. If protective measures are not in place, it may even cause the risk of suffocation.
