In 2023, we leaped over the milestone of 100 CBTC lines in China! In 2024, let’s strengthen our faith and march towards the future together on the new journey of creating a world-class professional leading demonstration enterprise!
Demonstrating responsibility on the front line
The signaling system renovation team of Shenzhen Metro Line 3 overcame difficulties to forge ahead with determination and make further progress, demonstrating the responsibility of CASCO people.
The signaling system of Shenzhen Metro Line 3 has been renovated. With a total length of 43.06km, the existing line is designed with 31 stations, Henggang Depot and Central Park Stabling Yard. The fourth phase of Line 3 is a route about 9.28km long, with 7 stations and a new Pingdi Stabling Yard. A total of 76 trains are now running in the existing line, 12 new trains were purchased for the fourth phase of the project, and 10 new trains were purchased for the line network. The project contract was signed in June 2023. As the CASCO’s 100th CBTC project in China, it is scheduled to be open on December 28, 2024, and the construction period is shortened by more than half compared with normal renovation.
Looking back on 2023, we completed the high-quality delivery and commissioning of the fully automatic signal control system for the ZHENGXU Line, while looking forward to 2024, we will continue to support the safe and stable operation of this railway.
The ZHENGXU Line is the backbone of the intercity rail transit network in the Central Plains urban agglomeration, linking up Xinzheng Airport, Zhengzhou Airport Economy Zone, Changge, and Xuchang. After the line opened for operation, through the "high-density, short-marshaling" bus-like operation, it has provided a convenient and fast option for people to travel between Zhengzhou and Xuchang, playing a very important role in promoting the "Zhengzhou-Xuchang Integration". In addition, this line is also the first GOA4 fully automated inter-city railway line using CASCO’s independent CBTC system.
The party member commandos of the Jinan project team have always kept their original aspirations and mission in mind, taken root on the front line and devoted themselves to construction. Their tenacious working style enables them to win each tough battle.
In 2023, the Jinan project team of the National Railway System Department completed the CTC3.0 projects for Laixi-Rongcheng High-speed Railway, Ji’nan–Zhengzhou High-speed Railway, Rizhao Lanshan Shugang Railway, as well as for Yanzhoubei Railway Station, Rizhao Railway Station, Hutian Railway Station, and Heze Railway Station. Throughout the year 2023, the project team completed 233 TDCS/CTC construction projects, including 3 Class I, 11 Class II and 219 Class III construction projects, contributing endlessly to the company's high-quality development and the construction of China into a transportation power.
In 2023, the project team of Chengdu Metro Line 19 overcame numerous difficulties and completed multiple difficult splitting and access tasks. In 2024, we will contribute to the development of Chengdu metro network with fuller enthusiasm and more solid work style.
The Chengdu Metro Line 19 project team used more than 90 night construction possessions to complete the installation and commissioning of 370 beacons on the existing line, the renovation of platform doors at 13 stations, the system upgrade of the existing line, the splitting and reverse upgrade of systems, the expansion of the control center and the commissioning of the EMU trains.Zero violations and accidents happened during the entire construction period, and no conditions that affected normal operations of the next day occurred. The high-level implementation of the project has been highly recognized by the owner at all levels and unanimously praised by the evaluation experts.
In 2023, we bravely shouldered heavy responsibilities, overcame difficulties such as tight construction schedules and scheme changes, carefully planned and completed project delivery with high quality.
Wuhan Metro Line 19 is the suburban express line in Wuhan's rail transit network and is the 7th metro line which uses CASCO's technology in Wuhan. During the implementation of the project, the party member commando team of the project bravely shouldered the heavy responsibility, overcame difficulties, kept a close eye on the nodes, organized scientifically, and actively coordinated internal and external resources. The team completed the EMU commissioning of the signaling system in only 25 days, and obtained the third-party safety certificate of test run in September 12, creating the record of the shortest EMU commissioning in Wuhan, and demonstrating CASCO’s powerful operational delivery capabilities. On December 5, the project obtained the third-party safety certificate for initial operation with passengers, and was officially opened on December 30. The delivery was completed with high quality, winning the recognition and praise from the owner.
Despite the cold winter, CASCO people fearlessly built up the Lanzhou-Zhangye line like a long dragon passing through the Wushaoling Mountains to form a new Silk Road at the foot of the Qilian Mountains. Looking back on 2023, we have cooperated sincerely, braved the severe cold, and tackled difficulties to ensure the orderly progress of the on-site commissioning work of the Lanzhou-Zhangye High-speed Railway.
The giant dragon extends far along the Silk Road. The newly built line of the Lanzhou-Wuwei Section of the Lanzhou-Zhangye High-speed Railway is 194 km long, with a design speed of 250 km per hour. It leads from Zhongchuan Airport Station, passes through Yongdengbei, Tianzhuxi, Heisongyi, Gulangbei, and ends at Wuweidong. The entire line is designed with 5 stations. Looking forward to 2024, we will work hard to fulfill our promise of "Fully Protected and Fully Assured" with full spirit and high morale, and deliver satisfactory results on schedule with high quality.
Braving the summer heat and the winter cold, CASCO delivered the Nanning-Kunming Railway with notable details. The impeccable quality demonstrates our craftsman's aspiration.
The first and second batch of overhauls of computer interlocking (some stations), TDCS and monitoring systems of the Nanning-Kunming Railway in 2023 were the annual key project of China Railway Nanning Group Co., Ltd. (a total of 15 stations). The project needed to be completed within 3 months. The entire Nanning-Kunming Railway is built on undulating terrain, with stations located in steep, sparsely populated areas with poor traffic infrastructure. In the face of the tight schedule, CASCO attached great importance to unified coordination and command. The Nanning project team braved the difficulties with a high sense of responsibility and successfully completed the 2023 overhaul project of Nanning-Kunming Railway in accordance with user requirements, and presented satisfactory answers to the owner with excellent results, winning the owner's praise and recognition.
After writing this new chapter, we keep the mission in mind and march forward.
Based on the Chongqing-Kunming High-Speed Railway, the construction of Kunming EMU Depot project was started in November. During the process, despite many user requirements and design changes, the software and on-site construction were successfully delivered, and the project was successfully opened as scheduled. The project has laid a solid foundation for the subsequent extension of the Chongqing-Kunming High-speed Railway into Kunming.
CASCO leads up in smart travel and create convenient services.
The Kunming Smart Station Pilot Project is the first commercial contract for smart station, which includes a smart passenger guidance system, a smart customer service system, a remote video seat system, a 3D dynamic display system for station operation, an AR panoramic station patrol system, and an alarm system for abnormal events with smart video analysis. Since the project was approved in early 2023, it has gone through several rounds of user demand mining, scheme design, and on-site construction, and has now entered the late stage of software debugging. The passenger service of the system was officially launched on January 2, 2024. Once fully functional in March, the system will see great improvement in terms of passenger transportation service, passenger guidance, station management, and operational safety.
