Abstract: Complicated and difficult mountain railways have many difficulties such as complex topography, strong geological structure activities, and frequent geological disasters. This poses a huge challenge to emergency communication guarantee. It is urgent to explore an emergency communication system solution suitable for complex and difficult mountain railways. Based on the current situation and the existing problems of railway emergency communication, combined with the complex and difficult characteristics of mountain railways, the paper proposes to build a railway emergency communication system of unifying interconnectedness, multi-network integration, global coverage, rapid deployment, and accurate positioning according to local conditions, and puts forward the implementation strategy of emergency communication center platform, emergency field equipment, emergency communication site access network, especially emergency communication coverage in tunnels is proposed, which provides reference for the construction of railway emergency communication system in complex and difficult mountainous areas.

Key words: complicated and difficult mountain railway, emergency communication center platform, emergency field equipment, broadband satellite, emergency communication coverage in tunnels
