Beijing Subway Line 7 (Phase II): complete signal commissioning in 60 days

Beijing Subway Line 7 (Phase II) opened on the same day of Guiyang Rail Transit Line 1, is the eastern extension line of Line 7 (important backbone line in the east-west direction of south Beijing), with the full length of 16.6km and radiating Chaoyang District and Tongzhou District.

The signal commissioning period for Line 7 (Phase II) is only 60 days. TCT has to complete the commissioning of all single-vehicle, multi-vehicle and multi-vehicle running chart of the whole line within 60 days, and there are 115 commissioning points. At last, TCT completed all commissioning tasks successfully.

The above achievement not only due to the hardworking of all site commissioning staff, but also owe to the “integrated, high-demand-fitness, modular, standard and replicable” CBTC signal system of Line 7, all interfaces are transparent and open, which provides favorable conditions for the system transformation, upgrading and commissioning.

Hohhot Metro Line 1: the first clouding metro in China

On December 29, Hohhot Metro Line 1 was formally put into operation, becoming the first ATS clouding metro line in China and starting the clouding times of urban rail transit.

It is reported that ATS clouding means ATS stored in cloud, which can greatly save the calculation, storage and processing resources and effectively solve the problem that each station should be equipped with station-level server and terminal under the traditional system architecture.

According to the estimation of experts, “Urban rail cloud” project will achieve considerable benefits in Hohhot, increasing the resource utilization ratio by more than 50%, saving the preliminary investment by about 40%, saving the labor cost by more than 30%, increasing the whole platform safety by more than 80% through the safety system of “inter-net isolation and intra-net protection”, and improving the service reliability by more than 50% through the three-level guarantee mechanism of primary center, disaster recovery center and station cloud node.

However, ATS clouding of Hohhot Metro Line 1 is only the first step of urban rail cloud. TCT is making effort to create the line into national urban rail demonstration and excellent project and accelerate the coming of smart urban rail era.

In the future, TCT will take urban rail cloud as the basis, data analysis and management as the core and digital service as the interface, creating the smart urban rail era with new technologies such as 5G, IOT, big data and AI.

Chongqing Rail Transit Loop Line: Tackling with the world-class difficult problem of signal system interconnectivity

On December 30, Chongqing Rail Transit Loop Line (Southwest Loop) was opened. With the full length of 9.5km, the line has 5 stations: Xiejiawan Station, Olympic Sports Center Station, Chenjiaping Station, Caiyunhu Station and Erlang Station. After operation, the line will provide convenience for the travel of residents along the line and promote the social and economic development of surrounding area.
