Before the merger of CNR and CSR, the major locomotive and rolling stock manufacturers in China were the manufacturing companies under these two groups. The two major manufacturers of locomotives are CRRC SIFANG and CRRC CHANGCHUN Railway Vehicles Co.,ltd. In 2004, in the China Harmony technology introduction negotiation, because foreign technology manufacturers could not be bidders, they had to participate in the bidding by joint venture or technology transfer with domestic manufacturers. In this process, Bombardier was the first to set up Qingdao Sifang Bombardier Railway Transportation Equipment Co. After that, Sifang Locomotive and Kawasaki Heavy Industries joined hands to focus on the CRH2 series. Changchun Railway Vehicle, which initially wanted to cooperate with Siemens, turned to Alstom because the negotiations did not go well; Siemens made a compromise in 2005 and joined hands with Tangshan Railway Bus to produce CRH3C. In 2004 and 2005, China's rolling stock manufacturers formed a four-company pattern through two technology introductions. The former China North Railway Group's CRRC changhun railway and CRRC tangshan and China South Railway Group's Sifang Locomotive and BST. Later, China South Railway and North Railway merged to form the China Railway Group, but these four companies manufacture most of China's rolling stock. In the era of "Fuxing"locomotives, Puzhen vehicles joined the production team again.

The pantograph monitoring system is an integral part of modern railway surveillance, designed to ensure the continuous and efficient operation of trains by providing real-time monitoring of the pantograph's performance and status. The pantograph, a critical component of electric trains, is responsible for maintaining contact with the overhead lines to draw power for the train's propulsion and systems.

Abstract: The paper briefly introduces the principle and application status of the video monitoring system for the EMU coaches by introducing the video monitoring server, coach camera, pantograph monitoring camera, monitoring screen, and other significant equipment configuration and parameters, describing The current status of the video CCTV system of EMU coaches, combined with the current development status of the EMU and the application prospect.

With the continuous development of railroad informatization in recent years, the locomotive onboard safety and protection system data has become an essential source of operational information for locomotive operation, maintenance, preparation, etc. However, in the dumping of inspection data, it is necessary to manually use the dumping device in the preparation workshop, which is time-consuming, labor-intensive, and prone to errors and omissions. When locomotives are put into storage at night, the energy and physical strength of the preparation personnel decreases, which inevitably causes a decline in operating standards and even labor safety problems. There are cases when the cause of an accident cannot be confirmed due to analog video during the ground analysis of video data. Unable to ensure the proper locomotive operation

The system uses a 60GHz high-frequency millimetre wave, which has the advantages of mature technology, large bandwidth, no spectrum application, and low interference far away from common civilian frequency points. In traditional wireless communication, its oxygen-degradation transmission characteristics make it difficult to transmit over long distances, and its application is limited. At the same time, this feature fits the needs of short-range communication and signal leakage prevention in vehicle-to-ground backhaul scenarios.

Locomotive automatic video monitoring and recording subsystem, as an essential part of the railroad security system, can maximize the prevention of various crises and protect the safety of railroad operations. However, the existing system's onboard video is analog, and the video resolution and picture quality can no longer meet the high requirements of the scene. To solve this problem, Shandong Tienuo Intelligent Co.,ltd Achieve a systematic upgrade from analog video to digital HD video for this problem.

Mobile video surveillance cameras have been an indispensable tool in ensuring safety and security on trains. These cameras provide real-time surveillance of train compartments and help in investigations. Mobile video surveillance cameras have become smaller, more reliable and cheaper, making them easier to use for train operators of all sizes. It is crucial to protect the privacy rights and ensure the responsible use of data. Mobile video surveillance cameras are an important addition to train security and safety measures. They should be promoted.

The CRH series has been the basis for continuous innovation in high-speed trains in china. Pantograph as a crucial electrical connection component have also evolved in this process.The pantographs play a important role in receiving high power from the contact network for the single-phase AC 25kV high voltage power required by the rolling stock. The total traction power required by high-speed trains is much greater than that of ordinary trains. At higher speeds, the air resistance also increases. Considering the requirements of reducing air resistance and noise, the number of pantographs on high-speed trains should not be too many. For 8-car trains, China adopts the single-arch pantograph method, i.e., only one pantograph is used during the operation of the trains and considering the requirements of reliability and redundancy, two pantographs are installed on each train. When the rolling stock is in process, one of the pantographs can be selected to be raised and the other pantograph folded.

The system carries out intelligent automatic analysis of locomotive video, realizing the whole process of traceability of crew standardization operation and driving safety and escorting the production of safe railroad transportation.

The intensity of the war between Russia and Ukraine is expanding beyond the battlefield. Following the financial sanctions marked by SWIFT, the IT, automotive, chemical, media, sports, education, and entertainment sectors have also been sanctioned one after another, up to the "cut-off" sanctions in the energy sector. Recently, the rail sector has joined the ranks of these sanctions. The International Union of Railways UIC has kicked former Russian Railways RZD, Belarusian railroad company BCh kicked out of the UIC membership list. The war between Russia and Ukraine is expected to significantly impact the rail industry in the coming years, not only in Europe, and Azure Track Rail brings you a complete analysis.
