Building a dream after the 1980s

On December 16, 2019, Chengdu Guiyang high speed railway was officially opened to traffic. Chengdu and Guiyang, two provincial capitals, can be reached as soon as 2 hours and 58 minutes. The total length of the line is 648 km, and the design speed is 250 km / h. Changning, Xingwen, Weixin, Zhenxiong, Bijie and other Yunnan Guizhou Sichuan junctions are the first high-speed rail in history. (people's daily.cn, December 16) the

0000 peak is the first mountain high-speed railway in the world, known as "the high-speed railway on cloud". Walking through the clouds, passing through the mountains and overlooking the phantom, its landform is like a "funnel". Sichuan Basin is the bottom of the "funnel". It climbs up along the 53 large folds on the side of the "funnel". After 138 kilometers of gas field, coal bearing strata and 197 kilometers of karst landform, it climbs all the way to the top of the "funnel" on the Yunnan Guizhou Plateau. No wonder Li Bai, the poet, also sighs: "EEE, wailing for the sword : I've got a long career in music! A 6031 a 6031 can't escape the word "difficult" when driving high-speed rail in such a mountainous area. The altitude difference of 2000 meters makes the motor car climb 10 floors every kilometer. When climbing the building, it will make the eardrum swell and sometimes tinnitus. The rail surface becomes wet and slippery due to the influence of the mountainous climate conditions, and the motor car set is prone to "sliding". The ratio of bridges and tunnels in the whole line has increased by 81.5% The frequency of entering and leaving the tunnel, especially when the dark light suddenly meets the strong light, people will have a transient conditioned reflex of blurred vision, dizziness and closed eyes. It can be seen that a good "steering wheel" of "high-speed rail on cloud" is an all-round physical and mental test for motor car drivers. A 6031 a 6031 a 6031 a 6031 from Chengdu Locomotive Depot of Chengdu Railway Bureau Group Co., Ltd. learned that the first driver of the day was two "post-80s" young Party members. Whether they could successfully start a good leader and complete their mission with honor attracted the keen attention of the whole family. The spotlights of all major media also focused on him On them, some netizens left a message saying, "are they experienced enough? After 80, is that ok? "

the author believes that when passengers get on the train, the responsibility of the whole EMU will be on the driver's shoulders. Only when they drive steadily, can tens of millions of passengers be safe. For passengers, Chengdu Guiyang high speed railway is a scenic tourism line, but in the driver's eyes, all the scenery may be just the dashboard in front of the narrow cab, no matter how beautiful the scenery is They are not allowed to be nostalgic. The speed of high-speed rail cars is like "flying close to the ground". Maybe people think that the faster the high-speed rail "flies", the more powerful the driver is. In fact, if the high-speed rail train stops at the designated position on time, stably and accurately, it is called high level. The 12.5km yujingshan tunnel of

Chengdu Guiyang high speed railway between Weixin old city station has a 30 ‰ gradient long and large ramp. When going up the slope, it needs to be operated by hand in the whole process to prevent late operation. When going down the slope, it is necessary to observe the changes of instrument display and braking current of EMU at all times. The control is not good and it is easy to overspeed. In order to achieve punctuality, stability and accuracy of the train, it is necessary to keep the EMU running with the best speed value close to the speed line, which is like letting a person draw a straight line of tens of meters without skew by hand. It can be imagined that in this case, a straight line without skew is drawn. Using the popular words of the network, it is really "south up and south up". A 6031 a 6031 "there are no other skills to drive high-speed rail well, only hard work and hard practice." It is understood that in order to ensure the smooth operation of Chengdu Guiyang high-speed railway to the maximum extent, the two first drivers have been put into the technical team composed of 20 people since August this year. Among these 20 people, the post-80s generation are everywhere, all of which are technologies such as "the first driver of Sichuan EMU skill competition", "top 10 young pacesetters", "global technical experts", "May 1st Labor Medal of Sichuan Province" over the years With the help of operation essentials and fault handling experience of multiple EMUs, nendaren Xingyao has carried out a lot of preparatory work, such as various simulation operation, double isolation state experiment, driving test according to the diagram, fault simulation, emergency drill, etc. through continuous exchange and discussion, they have simulated the scene of difficult road section, exercised muscle operation memory, recorded key data and nodes, and checked driving Driving knowledge blind area, such as "where to start braking, which node needs to control how much speed, where to start entering into the split phase section (EMU driving into the split phase section will experience the process of power failure and power supply recovery, and operation failure will make passengers feel the start and stop falter, which will generate shaking)", they are all familiar with it and respond in an orderly manner, making sufficient preparations for the opening of the first line: "this one I have driven countless times, and I believe I can drive well. " A 6031 a 6031 10:53, the first c6041 train successfully arrived at Guiyang station, after 80, the first driver completed the mission! Following the initial opening of Chengdu Guiyang high speed railway, the railway department will adjust the national railway operation chart on December 30, 2019. The number of Chengdu Guiyang EMU trains will increase from 20 to 44 for daily lines and 14 for peak lines! The people's railway loves the people, and Wumeng is singing loudly!

a powerful transportation country, railway first! Today's youth, march forward bravely! Build dream high-speed rail, after 80 already set out! After 80s, it's OK!
