From the night of December 12th to the day of the 14th, many citizens took the tram Xijiao Line to check in the snow scene in Beijing. In order to ensure the safe travel of citizens in extreme weather, the front-line workers of the tram braved the wind and snow, were on duty, overhauled and maintained, and patrolled, and worked hard for more than 30 hours.
In Beijing late at night, the cold wind is biting, and the low temperature after the snowfall will cause frost on the catenary and affect the power supply of the train. From 0:00, the staff on duty at the platform of the western suburbs line monitor the temperature and humidity of the environment at any time, run a rolling car every 30 minutes, and drive on the track without interruption. From 1 a.m. to 4 a.m., the track team composed of 6 personnel stuck to the Xiangshan fork area and the Bagou fork area, maintaining an emergency state at all times, and continuously clearing the snow on the turnout.
Vehicle professionals use the window time after the end of operation to focus on the running parts of the on-line train the next day, clean up the mixed ice and snow, check the amount of sand added to the sand scattering system, and test the bogie, wheelset, air conditioning, lighting, wipers and other driving systems that are greatly affected by extreme weather, so as to ensure the safety and reliability of each on-line train.
The catenary is the "lifeline" of the western suburbs line, and the power supply professionals should use the night maintenance period to meet the "test" of snowfall, inspect and measure the catenary, and carry out manual defrosting work at any time to ensure that the pantograph contact state is good and that the train pantograph receives electricity normally.
In the cold night, the maintenance personnel maintained the lights on the line, inspected the pump room in the tunnel, manually drained the water, and inspected the heating pipeline. 8.8 kilometers of flexible catenary, 13 turnout and level crossing signal priority equipment, they continue to clean the road, track, turnout, train entry and exit section line, maintenance warehouse, and use library.
After the heavy snowfall, the whole city is like a beautiful picture wrapped in silver, and in the snowy night, the car does not stop, and people do not sleep. Behind the "most beautiful western suburbs line" is the "most beautiful worker" who sticks to his post.
