Digital network deployed on Mongolia’s new coal line

TETRA systemTeltronic has installed the TETRA system for the Tavantolgoi – Gashuunsukhait railway line serving the Tavantolgoi coal mine.

Under the contract, Teltronic has installed a complete communications solution on TETRA digital technology based on its Nebula infrastructure, which includes two control nodes (main and redundant) as well as the indoor and outdoor base stations necessary to cover the 250 km of the track, and which will have to withstand the extreme temperature fluctuation of cold and hot, sandy, windy environmental conditions that occur in such a hostile environment as the Gobi of Mongolia.

In addition, the company has also supplied the on-board radios for each of the 16 locomotives that will serve the line, as well as the portable, mobile – installed in the maintenance vehicles and desktop terminals used by control, security and maintenance personnel. The TETRA system is completed with Teltronic’s control centre and call dispatching solution, CeCoCo, with two operator stations.

“Due to the environmental and operating conditions, we needed a robust and reliable radio system that would guarantee communications along the entire line without a single point of failure. Teltronic’s solution offered us the levels of availability and quality of service necessary to operate the line with total security”, said Bat-Amgalan Tumurbaatar, the director of telecommunication and signalling department of Bodi International, the Mongolian railway infrastructure and mining company responsible for the project.

The Tavantolgoi – Gashuunsukhait railway line will be operated by the state-owned company Tavantolgoi Railway and is expected to be a major boost to the Mongolian economy. The railway will run through the most southern part of the country, along a 250 km route that includes a total of 6 passing sidings and 2 train stations and will shorten travel time and transport costs, attracting road freight volumes to the railway.

In 2021, Progress Rail was awarded a contract to deliver 16 locomotives for the line which is expected to have a capacity of 30 million tonnes per year.
