wireless fire capable of carrying the equivalent of 3 Eiffel Towers at once.
The train utilizes technology that connects locomotives virtually.According to Chinese state television station CCTV, this technology is said to be able to increase the country’s freight transport capacity by 50 percent without the need to build new rail lines.

This technology connects multiple freight trains via a wireless system instead of a physical link.
On Monday (8/12), trials carried out on the Baoshen Railway in Inner Mongolia featured seven freight trains with a combined load capacity of 35,000 tons, equivalent to 3.5 times the weight of the Eiffel Tower.These convoys ran much closer together than would normally be necessary when they operated as a single unit.
This group control system was developed by China’s state-owned coal mining company Shenhua Energy Company and other domestic organizations.

, Tuesday (9/12), China has expanded its rail freight transport capacity for decades and transported more than 3 billion tons of goods in the first three quarters of this year.
The Bamboo Curtain country is also strengthening rail connections to other countries, with services such as the China Railway Express which provides connections to dozens of countries in Europe and Asia and transports goods.
According to a study published two years ago in the journal Mathematics by researchers from Central South University in Changsha, Hunan Province, building new railway lines to meet growing demand for goods is very expensive, so measures such as increasing the length of trains or shortening the time interval between train departures can save costs.
In the latest trials, trains each carrying 5,000 tonnes of goods operated in convoys over dynamically managed distances.The convoy uses a control system that relies on wireless signals and has no mechanical connections.
This allows trains to accelerate and brake without collisions or separations.This also reduces the braking distance required between trains.
In conventional train operations, trains are required to run a certain distance for safety reasons.Heavier and longer trains, especially freight trains, as well as trains moving at high speeds tend to require longer braking distances.
However, a virtual coupling system being tested in China allows this distance to be reduced by helping trains adapt dynamically to changes in speed.
The technology also allows more trains to operate without the need to build new lines or technically challenging single heavy freight trains.
China Shenhua Energy, a subsidiary of state-owned mining and energy company CHN Energy, has been gradually working towards achieving this, testing two light rail convoys earlier this year.
“By utilizing train-to-ground and train-to-train communications, this technology employs a two-dimensional control mode that integrates relative speed and absolute distance, enabling dynamic close formation operations,” CHN Energy said last August.
This technology can also help increase a train station’s throat capacity or the maximum number of trains that can be handled by a station entry and exit area.
CHN Energy said this achievement also made China the first country in the world to “master the group train operation control system.”
