In the past few days, China National Railway Group Co., Ltd. has taken effective measures to ensure the transportation of electric coal in winter. How can coal be loaded on a train? How many tons of coal can be transported by a train, and how many carriages are there in a 10,000-ton train? Let's go to the Tangbao Railway, an important channel for the transportation of coal from the West to the East, to find out!

The Tangbao Railway has a total length of 852.419 kilometers. It is jointly operated by China Railway Hohhot Bureau Group Co., Ltd. and China Railway Beijing Bureau Group Co., Ltd. It mainly transports coal and other white goods from Inner Mongolia and northern Shaanxi to Caofeidian Port.

How long does it take to fill a 10,000-ton train

At a coal loading station on the Tangbao Railway, a large train composed of 105 C80 empty gondola cars was pushed to the loading bay. With the opening of the upper silo, the black coal was dumped down. In less than 2 minutes, one car of coal completed the loading, topping, and dust suppression operations. In this way, it takes about 2 to 3 hours to fill 105 gondola cars.

This operation is repeated more than 500 times a day, and 5 trains full of tons of coal will depart from here and go to various places.

In order to alleviate the shortage of electricity in various regions and fully guarantee the coal demand for power generation in thermal power plants in various regions, Hohhot Bureau Group Corporation implements a priority transportation policy for thermal coal, taps the capacity potential of the Tangbao Railway’s special coal transportation channel, and realizes East China, Central China, and South China. Efficient interconnection in the Northwest region.

The Hohhot Freight Center reasonably arranges the loading plan at the stage, communicates with the coal loading station in a timely manner, grasps the demand of customers and the dynamics of the vehicle flow, ensures the efficient operation and seamless connection of all links, and improves the efficiency of transportation organization.

The lines along the coal transportation channel of the Tangbao Railway are beautiful, as evidenced by pictures!

In order to protect the ecological environment along the Tangbao Railway, the railway department has set up spraying devices and other dust suppression equipment on the coal loading line to evenly spray dust suppression agents on the newly loaded coal to form a protective film on the surface to prevent the coal from being Dust is raised during the operation of the train to achieve dust suppression and environmental protection.

Moreover, in order to implement the central government’s deployment requirements for carbon peaking and carbon neutrality, the railway department has vigorously promoted containerized transportation, guided coal, iron ore and other cargoes to be "bulk-to-collected" into containers, and coordinated logistics distribution and loading time. Efforts are made to pull and install, reduce dust pollution caused by storage, and jointly win the blue sky defense battle.

As of the end of September, the Hohhot Bureau Group Corporation had shipped 27 10,000-ton coal trains to Hong Kong every day, effectively ensuring the supply of winter coal in Inner Mongolia, Beijing-Tianjin-Hebei and other regions.

There is more than coal on the Tangbao Railway

As an important channel for the transportation of coal from west to east, Tangbao Railway also undertakes the important tasks of transportation of civilian resources and serving the Beijing-Tianjin-Hebei region.

On September 23, in the Shaliang Logistics Park of the Hohhot Freight Center, two reach stackers were shuttled back and forth, hoisting white tank containers and loading them on special flat cars. Four hours later, a container train full of bulk cement will rush to the Beijing-Tianjin-Hebei area along the Tangbao Railway to help local construction.

The marketing staff of Hohhot Freight Center actively help companies contact tank container manufacturers to develop detailed logistics plans for customers based on the small particles and easy dust of bulk cement. Through the method of inflatable filling, the cement loss can be effectively reduced, and the transportation process is clean and environmentally friendly. .

After transferring to railway transportation, the company has shipped 1.412 million tons of cement through Tangbao Railway, forming a stable industrial chain radiating the Beijing-Tianjin-Hebei region, serving the construction of key projects such as the Xiongan New District and Daxing Airport.

Hohhot Freight Center takes advantage of the location advantage of Shaliang Logistics Park to connect with Shaliang Station of Tangbao Railway to strengthen in-depth cooperation with enterprises. Since the beginning of this year, the throughput of the park has reached 2.205 million tons, a year-on-year increase of 51.6%.

Where the brakes of the coal heavy-duty train with 10,000 tons are all regulated.

The coal heavy-load 10,000-ton train has a single-trip transportation capacity more than three times that of ordinary freight trains. It is the freight method with the strongest carrying capacity, the most advanced equipment and the highest working standards in the bulk cargo transportation.

The total length of the 10,000-ton train is nearly 1,300 meters, and the towing weight is 10,000 tons. The handling difficulty is much higher than that of the ordinary cargo train.

The Jining Locomotive Depot is responsible for the 605-kilometer traction task on the Tangbao Railway, passing 174 bridges and 84 tunnels, including 9 long ramps above 12‰, with a maximum slope of 13‰, making it difficult to maneuver.

From an ordinary freight driver to a heavy-duty driver, a training period of no less than 2 years is required, and the mileage used for internship is about 160,000 kilometers.

Manipulating a 10,000-ton train on a growing downhill is like riding a slide with a bag of rice on his back. The train driver needs to adjust the brake at all times.

In order to ensure the safety of traction in special sections and meet the requirements of "careful control, precise control, and fine control", Jining Locomotive Depot summarized the "Tangbao Railway 24 brake curing operation method", and the operation details such as the location and speed of the brake are clearly defined. And the detailed requirements transform the individualized manipulation techniques into standardization, and realize the standardization and unification of manipulation.

The first perspective of a heavy-duty driver

There are more than 60 large and small tunnels in the crew traction section of Jining Locomotive Depot, and the longest Yanshan Tunnel is 21,155 meters long.

One tunnel after another will cause the flight attendants to have symptoms of dizziness and tinnitus. This group of heavy-duty drivers often maintain a "strange" posture when maneuvering the train through the tunnel: the tongue is on the upper jaw, the body is slightly forward, and the body is not allowed to sit firmly on the chair, and sitting on the chair is almost a horse step. It can effectively avoid the problems of visual fatigue and lack of concentration in the dark environment for a long time.

Tunnels one after another, travel during the day and arrive at night, and the flight attendants can't even feel the changes in sunlight during the journey. Sometimes the train goes down and sometimes turns, and they are accompanied by the lights passing through the tunnel. Being in a monotonous environment for a long time is a big test for the flight attendants.

It is also the traction train, the heavy-duty driver's tricks, revealing decades of knowledge everywhere, it is a realm of "man-machine integration", showing their precise control of the car and the line. Editor/Tian Zengpeng
