on january 1, 1975, the entire hunan-guizhou railway was opened to traffic.

on that day, wang jianguo was on duty at the xiaolongdong work area near liuji station in kaili city, qiandongnan prefecture, guizhou province to ensure the successful trial operation of the hunan-guizhou railway. "according to what my colleagues later described to me: kaili station presented a lively scene that day. , the queue waiting for the bus is as far as the eye can see, and the event is unprecedented. "

the completion of the hunan-guizhou railway has opened up a main road from the southwest to the eastern coastal areas, shortened the distance from the three provinces of yunnan, guizhou, and sichuan to some provinces and cities in central south, south china, and east china. it has played an important role in improving guizhou's transportation conditions and promoting guizhou's economy. social development is of far-reaching significance.

"it can be said that i personally experienced the opening and operation of the hunan-guizhou railway. i am very happy and excited." wang jianguo feels that he is lucky.

from that day on, 26-year-old wang jianguo plunged into kaili, a city surrounded by mountains. he was accompanied by the sound of sirens all day and night, and witnessed the crowds of people and goods carried by rolling wheels.

on october 1, 1949, wang jianguo was born in dong'e county, shandong province.

"because i was born on the day of the founding of the people's republic of china, my father had high expectations for me. he hoped that i would build the country and serve the motherland when i grew up, so he and his comrade fu xiufeng named me 'jianguo'." unfortunately, wang jianguo has never met. his own father.

in september 1951, wang jianguo's father unfortunately died in the war against bandits.

influenced by his father's deeds, wang jianguo determined to be a soldier when he grew up. according to his recollection: the title of his first composition after school was "i want to be a soldier".

when he grew up, wang jianguo lived up to his father's expectations and realized his ideals: in october 1969, wang jianguo enlisted in the army and served in the army for 5 years.

in april 1974, after retiring from the army, wang jianguo took the initiative to work in guizhou. "at first, he worked as a road maintenance worker in the guiyang works section of the chengdu railway bureau, and then worked in the security section of the works section for a period of time."

on new year's day in 1975, wang jianguo was transferred to the kaili works section of the chengdu railway bureau to take over the hunan-guizhou railway to ensure the successful trial operation of the hunan-guizhou railway. according to wang jianguo's recollection, at that time, he and more than 20 colleagues who were transferred from various public works sections across the province were on duty at the xiaolongdong work area next to the six chicken stations.

talking about his feelings on duty, wang jianguo said that he had only one idea at the time: to do a solid job and ensure the success of the hunan-guizhou railway trial operation. "everyone was very cautious at that time, and everyone was thinking about the same thing: we must ensure that the width is 1,435 mm." the rails are exactly the same in terms of width, height and level.”

after the hunan-guizhou railway was opened, it greatly facilitated people's travel.

"the car ride from kaili to guiyang originally took 5-7 hours, but it only takes more than 4 hours by train." wang jianguo said.

as a descendant of martyrs, wang jianguo was raised by his fellow villagers and taught reading and literacy by the party and government. the kindness of his upbringing is deeply rooted in his heart and he will never forget it in his life. after the hunan-guizhou railway was opened, wang jianguo followed the organizational arrangements and continued to work in the kaili public works section, and served as the first youth league committee secretary of the works section.

in the years that followed, wang jianguo witnessed many historical changes in the hunan-guizhou railway.

"when the hunan-guizhou railway was first opened, the vehicle equipment was basically coal-burning steam locomotives to pull passenger trains and freight trains. later, it was upgraded to diesel-burning diesel locomotives." wang jianguo told reporters that this upgrade is improving the running speed of the vehicles. at the same time, the transportation capacity of the railway has also been significantly improved.

by the 1990s, the economic development along the hunan-guizhou railway had become relatively mature. at this time, the hunan-guizhou railway began to implement the electrification upgrade project. the first implementation was the guiyang-yuping section in guizhou, which was completed in december 1988. this electrification upgrade has increased the annual throughput capacity of the section from yuping to guiding from the original 10.5 million tons to 17.8 million tons, an increase of 1.7 times; the annual throughput capacity of the section from guiding to guiyang south has increased from the original 9.7 million tons to 22.1 million tons, an increase of 2.28 times. "the implementation of the hunan-guizhou railway electrification upgrade project not only improves the railway's transportation capacity, but is also of great significance in promoting economic exchanges between the southwest region and the eastern coastal areas." wang jianguo said.

in 1999, the electrification upgrade of the entire hunan-guizhou railway was completed.

since then, shaoshan series electric locomotives have also begun to operate on the hunan-guizhou line, further increasing the transport capacity of the hunan-guizhou railway. at the same time, the former ministry of railways began planning to double-track the zhuzhou-liupanshui railway (including the entire section of the hunan-guizhou railway and parts of the guizhou-guizhou railway and guizhou-kunming railway). the project was finally completed on december 30, 2001. . during this period, wang jianguo also resolutely took on the important task of party secretary of the kaili works section of the chengdu railway bureau.

"before the late 1990s, the railway station buildings along the hunan-guizhou railway were basically very small and had outdated facilities." wang jianguo said that by the beginning of the 21st century, under the influence of the double-track reconstruction of the zhuzhou-liuzhou railway and other projects, hunan the train stations along the guizhou railway have been upgraded and renovated. some stations were directly demolished and rebuilt, while the remaining stations also had their appearance upgraded. "since then, trains have gradually become the preferred means of transportation for locals."

in order to meet the needs of china's sixth major railway speed increase, accelerating the development of the western region and the leapfrog development of railways, the hunan-guizhou railway carried out a comprehensive seamless long-track reconstruction in october 2005. construction began at zhuzhou tianxin station, the starting point of the hunan-guizhou line.

the content of the comprehensive seamless long rail transformation is to weld the original 25-meter-long rails into seamless long rails of more than 800 meters. "the use of seamless long rails can reduce line rail joints, reduce train vibration coefficients, and improve passenger comfort." reduce the labor intensity of railway maintenance personnel; reduce the friction coefficient between rolling stock and track surface, and extend the service life of locomotives and rails," wang jianguo told reporters.

in addition, wang jianguo has also witnessed the upgrading and transformation of the signaling system and catenary suspension methods of the hunan-guizhou railway. “the upgrade of the catenary suspension method is to transform the simple suspension into a chain suspension. simple suspension is prone to power outage and parking, while chain suspension is easy to stop.” the suspension can ensure uninterrupted power supply and safe and smooth operation of the locomotive.”

the wheel of the times is rolling forward, and the emergence of a new era is bound to replace or eliminate an old era.

from 18:00 on december 31, 2006, the hunan-guizhou railway merged with the shanghai-hangzhou railway, zhejiang-jiangxi railway, guizhou-guizhou railway (guiding to guiyang section), and guiyang-kunming railway to form the shanghai-kunming railway. the shanghai-kunming railway starts from shanghai station and ends at kunming station, with a total length of 2,633 kilometers. at this point, the names hunan-guizhou railway and guizhou-guizhou railway (guiding-guiyang section) no longer exist within the railway system and have officially become history.

on december 26, 2014, guizhou’s first high-speed railway, guizhou-guangzhou high-speed railway, was opened to traffic. since then, the gui-nan high-speed railway, the shanghai-kunming high-speed railway, the chongqing-guizhou railway, and the chengdu-guizhou high-speed railway have been put into operation.

the "green trains" that people have loved for more than half a century are slowly fading out of this era due to the emergence of high-speed rail. nowadays, most of the trains running on the railway tracks are high-speed rails that fly as freely as the wind.

however, between hunan and guizhou, the hunan-guizhou railway, which has long been "upgraded" to the shanghai-kunming railway, still plays an irreplaceable and important role.
