China's bullet trains are famous for their lightning-fast speeds, whisking passengers across vast distances in record time. But behind the scenes, there's a dedicated team ensuring that every journey is not only swift but also safe and healthy. During the pandemic, the importance of ventilation systems became paramount, especially in the train's relatively closed cabins.
Enter Liu Chuanhui and Liang Jun, mechanics at the Zhengzhou East Railway Institute, affectionately known as the \\"lung doctors\\" of the high-speed rail network. Their daily routine goes beyond typical maintenance tasks. At the end of each journey, they meticulously check the ventilation rates, replace filter screens, and thoroughly clean and disinfect the air conditioning systems. \\"It's like taking care of the train's lungs,\\" Liu says, highlighting the critical role they play in maintaining optimal air quality.
Thanks to their efforts, passengers can enjoy a comfortable and safe ride, confident that the air they breathe is clean and well-circulated. These 'lung doctors' embody the spirit of dedication and innovation, ensuring that China's high-speed trains remain a model of efficiency and public health.
