Nanning Rail Transit Line 4 is the backbone line on the south bank of Yongjiang, with the full length of 24.6km and 19 stations, the line starts from Hongyunlu Station in the west and runs from east to west, that is, reaching Longgang in the east via Dashatian Maturity Area and the new “City Card” Wuxiang New Region. As the backstage hero for the high-quality and efficient operation of Nanning Rail Transit Line 4, TCT provided the I-CBTC signalling system with the independent intellectual property during metro construction, which effectively improves the utilization ratio of line and equipment and fully meets the user’s specific requirements. By means of on-board equipment and track-side communication equipment, the line realizes information exchange between trains and station or control center and the train operation control, has the advantages of being independent, safe, high-speed, small in interval and flexible in ground-vehicle transmission mode, and guarantees the travel of residents in a high standard.


Promote the three-dimensional development of Nanning Rail Transit and prepare for interoperability


As the “transverse lines” of the “two transverse lines and two longitudinal lines”, the operation of Nanning Rail Transit Line 4 will strengthen the east-west connection on the south bank of Yongjiang, promote the formation of development belt in the area, and create a new pattern of “simultaneous development of four lines and accessibility in all directions” in Nanning. Meanwhile, Line 4 will also promote the industry, commerce, logistics, and people of old business area to radiate toward Wuxiang New Region rapidly, accelerate the development speed of the region, realize the coordinated development of old and new urban areas, provide strong impetus for the new center of Nanning and play a strategic role in strengthening the development of “multi-center” area and all districts.

In particular, the signalling system of Nanning Rail Transit Line 4 realizes interconnectivity of different signalling equipment and common corridor operation according to the interconnectivity specification requirement, the unified ground equipment arrangement principle, vehicle-ground communication protocol, and electronic map-making specification effectively improves the utilization ratio of line and equipment and provides a feasible and mature solution for the future interconnectivity and interoperability of Nanning rail transit network.


Ensure the high-level operation through strict scientific management


Facing the unexpected epidemic in 2020, TCT implemented high-standard epidemic prevention management. TCT carried out a series of effective prevention and control measures for personnel, materials, sites, and commissioning; established a platform for unified deployment of epidemic prevention supplies, monitored the health condition of all relevant personnel, sterilized the staff gathering places frequently; tested and sterilized the personnel and sites during commissioning, ensured the epidemic prevention and control during the epidemic period and safeguarded the initial operation delivery nodes of Nanning Rail Transit Line 4.

By means of constant technological innovation and project practice, TCT provided safe, efficient, high-quality, reliable, and sustainable rail transit signalling products and services for the users and passengers through independent core technologies. In the future, TCT will strive to move forward, grow constantly, and continue to create a rail transit that is more suitable for users’ demands and has more intelligent ecological civilization and local characteristics for more cities.
