752 1 jiajing railway, crossing the deep valley of Gobi, looks desolate and magnificent.

1954 10, northwest geologists went deep into Huashugou, Qilian Mountain and discovered this large iron mine with industrial value, which caused a sensation throughout the country. In order to develop Jingtieshan Iron Mine, the state decided to build Jiajing Railway.

After many stoppages, the railway was laid to Jingtieshan Station at the end of 1966. 1969101On October 20th, Jiajing Railway was handed over to lanzhou railway administration for management and officially opened for operation.

Later, on July 6th, 20 10, the electrification transformation of Jiajing Line started, and it was put into operation on October 20th, 20 165438/KLOC-0.

On July 20 19, we came to Jiayuguan, and came here to experience this extraordinary railway, starting from this railway station called "Greening". We don't know where the name of this station came from, but we know that great achievements have been made in afforestation in the northwest, which is obvious to all.

It is getting closer and closer to the departure time, and the small waiting room is soon crowded with Jiuquan workers in blue uniforms who are going to work in Jingtieshan Mine.

You need to take this green leather train -752 1 to enter Jingtieshan. It is one of the two pairs of passenger cars on Jiajing Railway at present. It starts from Jiayuguan and changes direction at the greening station. As the train doesn't stop at the platform line, everyone needs to cross the line.

Since March 20 16, the locomotive of our department has been changed from SS3 to HXD1C. The green leather car is not very eye-catching, but it is the "factory car" for Jingtieshan miners to go to work. Now SS7E of Lanzhou Bureau is in charge of this train, and the bottom of the train has been replaced by a 25G air-conditioned car.

In the past summer, in addition to factory workers, a large number of tourists will take this train to Qiyi Glacier. However, in 20 19, due to the closure of the July 1st Glacier, except for the two of us, there were only JISCO employees and railway commuters on board.

14:03, the train started slowly, drove out of Jiayuguan and galloped south at a speed of 50 to 60 kilometers per hour.

This train starts from Jiayuguan, changes direction in greening, stops at Qiaoxi, Binggou, Langwei Mountain and Shuanggou Bridge, and finally reaches the terminal Jingtieshan Station. Running more than 70 kilometers for more than two hours, the whole fare is only 4 yuan. (Redeemable 12306 membership points in some time periods)

When the train passed Lianhuo Expressway, a khaki ruin suddenly appeared on the left, which is the first pier of the Great Wall.

According to the staff on the bus, there used to be a station called Feng Chun, but it was abandoned and demolished, leaving only a trace.

Looking around, Fiona Fang is a vast Gobi stretching for dozens of miles, and the Qilian Mountains are rolling in the distance.

14:24, the train stopped at a station called "Qiaoxi". As its name implies, Qiaoxi Station is a station on the west side of the bridge, which is the No.1 Bridge of Beidahe River.

When the Jiajing Line was designed in the 1950s, a visiting Soviet expert was stunned by the bottomless Beidahe Gorge and asserted that "the bridge could not be built at all!" The Beidahe No.1 Bridge has just overcome this natural barrier, and we have to admire the cleverness of our engineers.

Today, Beidahe Canyon and No.1 Bridge have become one of the landmark buildings of Jiajing Railway. This breathtaking and magnificent landscape has attracted countless fans and photographers.

The train continued to move forward, and the Qilian Mountain in the distance was getting closer and closer. We were amazed by the sudden change of scenery from Gobi Desert to gully canyon, but it only took 65,438+00 minutes.

Jiajing railway goes deep along the edge of the canyon, and the peaks on both sides stretch for thousands of miles. Looking down, there is a huge gully under the iron shop, which is covered with rugged rocks. Steep and steep, it really makes people gasp.

14:50, the ice ditch station is here. When you come to the ice ditch in summer, you can only see the steep valley. In winter, it is really an ice ditch! The names of stations along Jiajing Railway are so straightforward.

Parked opposite are the dump trucks of JISCO, commonly known as "Old K Cars", almost all of which are K 16 models. It uses a three-axle bogie that is rare on freight cars, and the impact sound of wheels and rails is very unique. According to the conductor, the traffic volume of Jiajing Railway is not small, about 30 wagons a day.

The train slowly drove out of Binggou Station and meandered along the canyon washed out by Beida River parallel to Jinshan Highway.

Jiajing Railway is known as "nine bridges and eighteen holes". However, I saw my colleagues taking notes on the train. There are 20 tunnels (bridges are not recorded) along the whole line, of which the section from Binggou Station to Langweishan Station is the steepest section of Jiajing Railway.

The longest tunnel of Jiajing Railway is this Daluohaizi tunnel, with a total length of 3408.8 meters.

The mountains are too high, the valleys are too deep, and the terrain is dangerous and chilling. It is no wonder that when the chief designer of Jiajing Railway recalled the construction of the railway many years later, he could not help but sigh: "We have given ourselves a difficult problem."

After the Daluohaizi Tunnel came out, it was followed by the Second Bridge, which, together with the First Bridge, is one of the famous landmark buildings of Jiajing Railway.

Two kilometers later, the train arrived at Langweishan Station, which is a small station where the train will go. There are only a few small bungalows in the station. Fiona Fang, which is dozens of miles around the station, is deserted, and only two or three people are on duty at each station. Fortunately, there are many trains passing by every day, so it's not too lonely.

After leaving the Wolf Tail Mountain, the train moved forward close to the canyon, and the North River outside the window ran endlessly. The whistle of the locomotive sounded from time to time, drifting across the mountain canyon and echoing in the valley for a long time.

In order to overcome the height difference of nearly 1000 meters between Jingtieshan and Jiayuguan, the maximum slope of Jiajing Railway, which is only over 70 kilometers long, exceeds 20‰.

The weather in Qilian Mountains is changeable, sometimes cloudy and sometimes sunny. The temperature in Jiayuguan is over 30 degrees, and it drops 10 degrees after entering Dashan Canyon. Now the train is upgraded from a green leather car with windows to an air-conditioned car, which is good for passengers.

Beida River is like a knife. It took tens of thousands or even hundreds of millions of years to cut a grand canyon in the Qilian Mountains before such an amazing scene was seen.

However, the small shrub vegetation on the bank of Peking University has left a little vitality for this desolate Grand Canyon, as if it brought a little spiritual comfort to those who were shocked by the steep mountain in front of them.

After running for 2 hours 10 minute, the train arrives at the terminal-Jingtieshan Station on 16: 13. There is still a certain distance from the center of the mining area, and the scale of the station is not small.

Jingtieshan was originally named Huashugou, but the iron mine was discovered by the geological team. 1955, 15 In February, Gansu Province decided to name this place "Jingtieshan".

The station is surrounded by mountains, and there are several two-story office buildings, but the waiting room is a small board room next to it. Because the passengers who come to the car come and go at a time, there is no canteen nearby.

The Little Square in front of the station is full of buses carrying JISCO workers. It is 50 kilometers away from the July 1st Glacier Tourist Area, and now the tourist area has been closed.

In addition to the unified HXD 1C locomotive, the station also has DF7G switch machine. However, SS3 has gone offline and disappeared.

This majestic mountain in the distance is called "Phoenix Mountain".

In the early 1950s, a female technician from Team 645 of Northwest Geological Bureau fell off a cliff during an exploration work and was killed. She is only 25 years old. In memory of this female technician, the mountain where she died was later named "Phoenix Mountain".

But before he conquered, he was dead and buried in Xuefeng, leaving a good name.

Finally, we stopped at Jingtieshan Station for about 40 minutes, followed the employees of Jiugang who had left work to board the green leather car and took the turn-back train 7530 to return to the greening station.

After this round trip of green leather cars, we enjoyed the magnificent scenery of Jiajing Railway going deep into Qilian Mountain, and also felt that it was not easy for workers in the factory to commute by train. It's so cold in summer, not to mention winter. ...

Today, the staff trains of Jiajing Railway have been upgraded to air-conditioned cars. For train fans, it may not be as interesting as the experience of opening a window in a real green leather car. However, for the workers who often commute between the factory and Jiayuguan, upgrading the air-conditioned car by train can at least protect them from the cold wind and greatly improve their comfort. In short, it is an excellent thing.
