High speed rail for passenger transport and “10000 tons” for freight transport. The coal carrying capacity of the “10000 ton train” is two to three times that of ordinary trains, which greatly improves the capacity and efficiency of railway coal transportation. How can the “top students” in this freight train ensure the coal supply?
In January 2022, Haoji railway, the longest north-south coal transportation corridor in China, ushered in an important moment. The “10000 ton train” helped “Wujin” go south for the first time.
With a total length of 1831 kilometers, Haoji railway crosses the Yangtze River once and the Yellow River twice, is not only the longest coal transportation railway in China, but also the longest heavy haul railway built and operated at one time in the world.
Ulan Tolgoi gathering and transportation station is a coal logistics enterprise near haole Baoji Station. Recently, the gathering and transportation station is in full swing every day.
However, until 2021, the terminal has been in a state of loss. But in 2021, they realized a profit of 15 million yuan. This is mainly due to their joining the Haoji railway line, a major channel for coal transportation, in 2021.
Every day, more than 5000 tons of coal are sent to Haoji railway through haole Baoji Station. With the help of the advantages of Haoji railway, more than 30 coal enterprises, large and small, around the station are doing more and more business. Liu Guoquan, deputy general manager of Ulan Tolgoi container transportation station of Inner Mongolia Shilin group, is one of them.
in the past, if the sea entered the river, it took about 20 days to reach the inland power plant. Now the Haoji line is connected, and the time is basically within 48 hours. coal can be delivered to customers in 48 hours, which is directly related to the informatization and intelligence of coal transportation. Through 95306, a large comprehensive e-commerce platform, the coal transportation of Haoji railway has become fast and convenient. From loading, transportation to unloading in the power plant, dynamic tracking can be carried out through the online platform.
In order to ship the coal at the first time, it is very important to race against time and load the coal efficiently. The silo loading line is 3260 meters long, 950 meters in diameter and looks like an egg. In the process of coal loading, the train runs as usual, and the staff only need to press the button to fill quantitatively.
The automatic metering equipment can set the coal loading tonnage according to the load capacity of different models, calculated by the train with a single load of 70 tons, the loading time of each carriage is about 50 seconds.
In order to make better use of the railway trunk line of Haoji railway to realize the outward transportation of Mongolian coal, China Railway Hohhot Bureau has built and opened more than 20 special railway branches in the past two years, helping more than 30 enterprises in the coal producing area solve the transportation problems.
Jingbian east railway station is nearly 200 kilometers away from haole Baoji Station, the starting station of Haoji railway. It is the busiest station of Haoji railway. This is the largest marshalling station for 10000 ton trains of Haoji railway. After the coal from Inner Mongolia and Northern Shaanxi is transported here, it will be assembled into a “10000 ton train” and roar all the way south.
In Jingbian east railway station, there is a “flying tiger team” who is extremely busy every day. This team is composed of 9 shunters. Its main task is to be responsible for the marshalling, disassembly and adaptation of all trains on 18 tracks in the station, and about 30 coal transportation trains should be disassembled every day.
They either climb on the running vehicles, or run quickly under the vehicles, pick up and jump off, so they are also known as the “Flying Tigers” in the electric coal marshalling yard. In January this year, an additional 10000 tons of trains were opened on the Haoji railway, making their shunting operations even busier.
The “10000 ton train” operated by Haoji railway is currently composed of 105 special gondolas for coal. The total length of the train is 1350 meters. The maximum total traction weight of single trip is 10500 tons, twice that of the past.
“Before the first pass, after the second pass, three air ducts and four hooks” to complete such shunting operation process, they have to repeat 40 times a day, walk about 25 kilometers and climb up and down hundreds of times.
Hang yourself on the train for operation, which is not only for long-distance observation and signal confirmation in the process of shunting, but also for timely notifying the driver to control the speed and connect safely. Each train has to be hung at the same position for 30 minutes. The “Flying Tigers” have to be hung on the body for nearly 6 hours.
It is this flying tiger team that organizes vehicles filled with coal to form a 10000 ton “dragon”, so that the coal from Inner Mongolia and Northern Shaanxi can be transported more and faster to the South thousands of miles away.
The “10000 ton train” opened by Haoji railway has not only brought new challenges to the marshalling and maintenance personnel, but also brought a new driving experience to the drivers driving 10000 ton trains.
Haoji railway runs from the Loess Plateau with an altitude of more than 1400 meters to the plain in the middle and lower reaches of the Yangtze River with an altitude of only a few tens of meters. The North-South height difference is nearly 1400 meters. It is a major coal transportation railway transportation channel with the most ramps. The 10000 ton train has great impact and inertia, and it is more difficult to operate.
Li Yong is an electric locomotive driver in Yan’an locomotive depot of Xi’an Bureau of state railway. He has six years of driving experience in electric locomotives. He told reporters that 10000 ton trains have very strict requirements for start-up and shift afterforce. All operations should be accurate to seconds to ensure the accurate operation of 10000 ton trains.
Generally, Fuxing EMU has a total length of 208.95 meters and a total weight of 485 tons. The parking error cannot exceed plus or minus 10 cm. The length of 10000 ton train is 1350 meters, the total weight is 10500 tons, and the parking error is controlled within 20 meters.
From the coal bases in Inner Mongolia and Northern Shaanxi to the economically developed areas in the middle and lower reaches of the Yangtze River with two lakes and one river, the “10000 ton train” running on the Haoji railway is constantly refreshing the speed of coal supply.
half an hour observation: guard the lights of thousands of homes and forge hard power to ensure supply
The central economic work conference in 2021 highlighted the need to do a good job in the “six guarantees”, of which “ensuring energy security and ensuring the stability of industrial chain supply chain” is an important part of the “six guarantees”. Energy supply guarantee is not only related to economic operation, but also closely related to the lives of thousands of households. Whether it is Daqin Railway Co.Ltd(601006) with large traffic volume and high efficiency, or the Haoji railway that has just opened the “10000 ton train”, it is the hard strength to ensure energy supply. Thank those shunters, drivers, freight forwarders and maintenance workers who silently stick to the front line of guarantee and supply in the severe cold. I praise you
