【新春走基层】-30℃，他们在月光下守护高铁平安

Core Insights - The article highlights the critical role of contact network workers in ensuring the safe and efficient operation of high-speed trains during extreme winter conditions in China [1][10]. Group 1: Work Environment and Conditions - Contact network workers operate in harsh conditions, often at temperatures as low as -30°C, requiring them to perform inspections and repairs during the night when trains are not in operation [2][3]. - The work involves managing a contact network that carries 27,500 volts of electricity, which is essential for powering high-speed trains [2]. Group 2: Operational Procedures - The time when trains are not running is referred to as "window time," during which maintenance work is conducted. This is a critical period for ensuring the reliability of the contact network [3][4]. - Workers must meticulously check and account for all tools before and after their shifts, similar to a surgeon ensuring all instruments are accounted for after an operation [4]. Group 3: Team Coordination and Safety - The team is divided into groups for specific tasks, and safety is a paramount concern, especially when working at heights in freezing temperatures [3][9]. - Communication and vigilance are essential, with team members constantly monitoring each other to prevent accidents during high-altitude work [9][10]. Group 4: Impact on Transportation - The successful operation of the contact network has enabled the development of four high-speed rail lines in the Harbin Railway Bureau's jurisdiction, significantly enhancing regional connectivity and economic activity [10]. - The high-speed rail system has become a vital part of the local economy, facilitating tourism and travel across the region [10].
