The crowded Spring Festival has begun.
The shuttle train rushed to Tiannan and Haibei.
and the great rivers and mountains of the motherland.
Witness the return of the wanderer together.
The EMU train is at a high speed.
The moment in the same frame is even more shocking.
Many netizens sighed:
This is the speed of China".
This is China's high-speed rail."
Is the "meeting" of multiple groups of trains accidental?
How do they work in order?
Let's find out!
Why are there multiple trains in the same frame?
It is common for trains to meet and parallel on the road. For example, the Guangzhou-Shenzhen intercity railway is currently 4 lines in parallel, and in the future, 6 lines will be parallel; The Nanguang high-speed railway and the Guiguang high-speed railway are 4 parallel ......lines between Guangzhou South Railway Station and Zhaoqing East Railway StationAt a certain time, the train will meet when it runs to a similar section!
Of course, at the major hubs, busy trains depart or stop at the same time.
For example, Guangzhou South Railway Station not only undertakes Beijing-Guangzhou high-speed railway, Guangzhou-Shenzhen-Hong Kong high-speed railway, Nanguang high-speed railway, Guizhou-Guangzhou high-speed railway, Guangzhou-Zhuhai intercity railway and other lines, but also connects two EMUs to meet the requirements of EMU entry and exit maintenance.
During this year's Spring Festival, Guangzhou South Railway Station is expected to receive and depart an average of 1,285 trains per day, and 13 trains will enter and exit the station within one minute at the busiest time.
When trains from east, west, north, and south converge at the same station, this meeting point is often referred to as the "choke point". In the choke point of the station, it is also common for multiple trains to be in the same frame.
How does the train run in such an orderly manner?
The reason why the train can run in an orderly manner is that the railway dispatching system, which is known as the "super brain", plays a key role. The dispatcher controls the train operation through the CTC (Centralized Dispatching System) to ensure that the train runs in strict accordance with the order of receiving and sending the train timetable.
Under normal circumstances, the train timetable plays a guiding role in the operation of the whole line of trains, that is, the train goes to **, the train goes to ** and other issues.
In case of train delays, the dispatcher will intervene in time and readjust the train operation sequence according to the actual situation. The powerful dispatching system and the super professional skills of the dispatchers ensure the safety and smoothness of railway transportation.
The Spring Festival is approaching, and the flavor of the year is strong. The railway department continues to increase capacity, adjust in real time, and meet the travel needs of the majority of passengers by opening additional trains.
