In the vast land of the motherland

There is a dancing steel dragon

West of Datong, the coal capital, across the Sanggan Gorge

Cross the Yanshan Mountains and reach the coast of Bohai Sea

This is known as China's No. 1 heavy-duty road.

Daqin Railway

The Daqin Railway is 653 kilometers long.

It is the transportation of coal from west to east and from north to south in my country.

One of the main passages

20,000-ton heavy-load trains running one after another

Amaze the world

Today I will show you the Daqin Railway

To the end, there are so many cows!

The first heavy-load unit train

Only transport coal! Nothing else!

The Daqin Railway is the first railway in my country to operate heavy-load unit trains, the first double-track electrified heavy-load coal-transportation line in my country, and one of the most modernized freight railways in China.

What is a "heavy-load unit"? Heavy-load means that this railway can run heavy-load trains of 10,000 tons; unit means that this railway only transports a single type of goods, does not transport other goods, and does not run passenger trains.

Therefore, the trains running on the Datong-Qinhuangdao Railway are of fixed formation. The heavy trains depart from Datong, are unloaded at the Qinhuangdao wharf, and the empty trains return on the original train, forming a cycle of transportation.

The highest transport capacity of a single railway

Breaking multiple world records

On the Daqin Railway, a heavy-load train departs every 12 minutes on average, with an annual transport volume exceeding 450 million tons, setting many world records including the highest density of heavy-load trains on a single railway, the largest transport volume, the fastest increase in transport volume, and the highest transport efficiency.

The longest train in China

The locomotive is sandwiched between the carriages

The heavy-load train running on the Daqin Railway consists of 210 C80 vehicles and two Harmony 1 electric locomotives, with a total length of about 2,614.3 meters and can carry 16,800 tons of coal.

Heavy-loaded trains with a distance of more than 2.6 kilometers sometimes have to cross three or four bridges and tunnels at the same time, and even swing out of an S-bend. During operation, the driver needs to point his finger and call for help every time he encounters a signal, more than 600 times per trip.

The Harmony 1 electric locomotive is composed of two identical single-end cab four-axle locomotives connected by an internal reconnection link to form an eight-axle locomotive, forming a complete system. In layman's terms, the locomotive is composed of a pair of "twins" back to back, divided into two sections, A and B. The train driver can control the two locomotives from the cab at either end. There is an intermediate corridor connecting the two locomotives, which can be passed through in a flash.

The station line is longer than other stations.

Can accommodate 32 10,000-ton trains

Station track refers to the general term for other railway lines within the scope of railway stations, except for the main line. In my country, the length of station tracks of general I and II level lines is 1050 meters, and the longest is 1250 meters. However, at Yuanshulin Station, the loading station of Daqin Railway, the station track is as long as 6432 meters.

The 6 tracks in the station can accommodate 24 10,000-ton trains, the 3 dedicated lines can accommodate 8 10,000-ton trains, and the entire station can accommodate 32 10,000-ton trains.

The first double-track heavy-duty railway tunnel

The only way to transport coal from west to east

Jundushan Tunnel is China's first double-track heavy-duty railway tunnel and the longest tunnel on the Daqin Railway, with a total length of 8,460 meters.

As the only way for the Daqin Railway to transport coal from west to east, the Jundushan Tunnel was officially started in January 1985 and opened to traffic in 1989. The project won the Luban Award for Chinese Construction Projects.

China's largest dumper

It only takes 3 minutes to unload 320 tons of coal

Caofeidian West Station, located on the shore of the Bohai Sea in Tangshan, Hebei Province, is known as the largest cargo delivery center on the Daqin Railway. It has 20 tracks for loaded vehicles, 16 tracks for empty vehicles and 12 advanced car dumpers.

The 36 tracks can ensure the arrival and departure of 780,000-ton trains in a single day, and the 12 car dumpers can unload 8,388 cars in a single day, with a maximum daily coal unloading capacity of more than 670,000 tons.

A car tipper is a large-scale mechanical equipment specially used for unloading bulk materials from railway open cars. According to the structural form, it can be divided into rotor type, tilting type, end unloading type, compound type, etc. Among them, the most widely used is the rotor type car tipper.

Isn’t it more magical when the picture is accelerated?

The large dumper at Caofeidian West Station can dump four C80 special coal open cars at the same time, and it only takes three minutes to unload 320 tons of coal. It is definitely a "model worker" for unloading on the Daqin Line.

The control building with the most trains received and dispatched on the entire line

Daqin Railway "Dragon Head Station"

The control building of Hudong Station integrates seven major systems: vehicle, locomotive, engineering, electricity, vehicle, power supply and communication. It is the only centralized operation place for train dispatching and command named "centralized control" on Daqin Railway.

It is equipped with my country's most advanced centralized train control system, dispatching command system, train communication system and vehicle fault inspection system. It handles an average of 232 trains per day, with the peak daily coal transport reaching 1.38 million tons.

What does 1.38 million tons of coal mean? Assuming that 318 grams of thermal coal can generate one kilowatt-hour of electricity, the amount of coal shipped here every day can generate more than 4 billion kilowatt-hours of electricity.

The largest marshaling yard on the entire line

Heavy-duty transport “processing plant”

The marshaling yard of Hudong Station is located in the western section of Datong-Qinhuangdao Railway. It is connected to the Yungang, Kouquan branch lines and Datong hub via Beitongpu in the west, and to the Dazhun and Jingbao lines via Jiejiazhuang Station in the north. It connects to Qinhuangdao direction via Datong County in the east, and is responsible for the reception, combination, decomposition and through-train services of heavy and empty trains in various directions.

Almost all trains traveling to and from the Daqin Railway must be assembled at the Hudong marshaling yard, where marshaling operations such as locomotive replacement, train technical inspection, train crew transfer, and tail-end device inspection and installation for 20,000-ton, 15,000-ton, and 10,000-ton combination trains and unit 10,000-ton trains can be completed.

The first person to enjoy the special government allowance of the State Council

Heavy-load train driver

Around the Earth 40 times

Jing Shengqi is a 20,000-ton heavy-load train driver at the Hudong Electric Power Locomotive Depot of China Railway Taiyuan Bureau Group Co., Ltd. In the 28 years since he took office, he has driven heavy-load trains on the Daqin Railway for more than 1,400 round trips, with a total mileage of 18.5 billion ton-kilometers, which is equivalent to driving a 10,000-ton train around the earth 40 times.

He has completed 12 major research projects, among which the "Precision Operation Method of 21,000-ton Heavy-load Train" filled the technical gap in the world's heavy-load field and became the first heavy-load train driver in the national railway to enjoy special subsidies from the State Council.

The Daqin Railway carries nearly one-fifth of the country's coal transportation volume, and is responsible for transporting production coal, civilian coal, and export coal for the country's six major power grids, five major power generation groups, more than 380 major power plants, ten major steel companies, and nearly 10,000 enterprises.
