Core Viewpoint - The article highlights the challenges faced by railway workers in the Zhejiang Quzhou region due to extreme heat, emphasizing their dedication and the increasing demand for freight transport during high-temperature seasons [1][2]. Group 1: Working Conditions - The temperature at the railway freight yard has reached as high as 50°C, creating a hazardous working environment for the railway workers [1]. - Workers are required to wear two pairs of gloves to prevent burns from the hot train bodies [2]. - The team is busy with operations, completing five to six dozen coupling tasks in a single shift, indicating a high workload [2]. Group 2: Operational Demands - The freight yard is crucial for transporting coal, industrial salt, and containers, with an increase in operational volume during the high-temperature season due to rising demand for these materials [1]. - Daily operations involve multiple steps, including vehicle inspection, ventilation preparation, and route confirmation, all performed efficiently despite the heat [1]. Group 3: Team Dynamics - Workers take short breaks to hydrate and rest, demonstrating the importance of maintaining energy levels in extreme conditions [2]. - The camaraderie among workers is evident as they support each other through challenging tasks and share moments of relief during breaks [2].

Group 1 - High temperatures in Hubei province, particularly in Wuhan, have led to a surge in electricity demand, prompting maintenance personnel to conduct urgent repairs to ensure power safety for residents [1][3] - Maintenance workers on the 220 kV Yuesun No. 1 high-voltage transmission line are addressing overheating issues at connection points, which serve over 100,000 residents [3] - The protective clothing worn by maintenance personnel is made of tightly woven metal wires, providing safety against high voltage but also creating extreme heat conditions, with temperatures exceeding 55°C at work sites [5] Group 2 - Summer is a critical period for highway maintenance, with workers in Jiangxi province actively repairing road surface defects under high temperatures [7] - In the Jiangxi Quannan Expressway, the use of geothermal regeneration technology involves heating and recycling old pavement, with surface temperatures exceeding 200°C to enhance asphalt viscosity for better repair quality [9][11] - The geothermal regeneration process allows for 100% recycling of waste materials, ensuring high-quality repairs for minor road damages less than 5 cm deep, with strict control over asphalt temperature and surface smoothness [11]
