Caltta Supports Launch of World's First Panoramic Mountain Tourist Train for Initial Operations

On February 12, 2025, during the Lantern Festival, the Lijiang Snow Mountain Sightseeing Train commenced its initial operation amidst the magnificent scenery of Yulong Snow Mountain. This marked an important step forward in the innovative practice of Lijiang's "rail + tourism" model.

The first phase of the Lijiang Sightseeing Train project spans 20.713 kilometers, with five ground stations along the route: Tourist Center Station, Baisha Ancient Town Station, Yushui Village Station, Dongba Valley Station, and Yulong Snow Mountain Station. The train features a modular articulated high-floor design, accommodating 210 passengers, and reaching a maximum speed of 70 kilometers per hour. With an elevation difference of 700 meters, this route not only carries the innovative mission of Lijiang's "rail + tourism" but also represents a significant breakthrough in China's core technology for high-altitude sightseeing rail transit.

Caltta provides advanced wireless communication solutions for this project, based on LTE technology and the B-TrunC standard, constructing a unified dedicated wireless communication platform. This platform supports comprehensive transmission of various train-to-ground wireless business data, including train operation control, passenger information system (PIS), video surveillance (CCTV), and trunking communication. Reliable QoS assurance is provided based on the priority of different services, along with a variety of wireless coverage solutions for different scenarios and business models, ensuring network stability and reliability.

During the project implementation, the Caltta team overcame technical challenges posed by the harsh ecological environment of the plateau, complex mountainous icy and snowy climates, long steep slopes, and sharp curves. They successfully built a tram wireless communication network that meets the high demands of tourist rail transit. Especially under long steep slope conditions, the team optimized the base station placement scheme and specially designed the transmission medium, ensuring high safety and reliability of the system while maintaining energy efficiency and environmental benefits.

The Lijiang Snow Mountain Tram is not only a pioneering project of green construction technology for plateau tourist rail transit but also an important part of the Great Western Yunnan Tourism Rail Transit Loop. The station buildings combine the surrounding architectural forms, cultural background, and regional characteristics, achieving "one station, one scene" and creating landmark buildings rich in regional features. The customized outdoor beautification covers provided by Caltta integrate rail transit with the natural landscape of the scenic area, significantly enhancing the quality of tourism in the area.

Caltta has always aimed to serve the high-quality development of transportation infrastructure with advanced technology. With profound expertise and an innovative spirit, Caltta has undertaken wireless communication network construction for over 80 rail transit lines nationwide, including multiple trams in Yunnan and Kunming Rail Transit Line 5. In the future, Caltta will continue to promote the innovation and development of wireless communication technology for rail transit, contributing to the intelligent construction of global transportation infrastructure.
