CCTV News: During the Spring Festival travel rush, when taking the high-speed train, you will see a string of dot-shaped indicator lights above the seat and below the luggage rack, which are divided into three colors: red, green and yellow. What are these indicator lights for? What does different color indicators mean? Mastering some common sense of high-speed rail may be of some help to take the high-speed rail.

The string of indicator lights of different colors above the seats of high-speed rail EMU trains represent the use of seats. Moreover, the indicator light system is connected to the railway 12306 passenger ticket system, which obtains data from each station along the train in real time, and displays real-time ticket information through the indicator lights of train seats. Railway staff and passengers can determine the sales of train seats by identifying indicator lights of different colors. Specifically:

When the red light is displayed, it means that there are passengers at the current station and the seat has been sold. If it is still empty at the moment, it may be that the passenger will leave temporarily, and it is not recommended to take a temporary seat.

When the yellow light is displayed, it means that there are no passengers at the seat at the current station, but the seat at the next station has been sold and the passengers are about to get on the bus; passengers who have not bought seats can take a seat temporarily. When passengers who buy this seats should take the initiative to give up their seats after getting on the bus, so as not to cause unnecessary misunderstandings.

When the green light is displayed, it means that there are no passengers at the seat at the current station and the seat has not been sold. Passengers who have not bought seats can take a temporary seat.

Zhang Shaomin, conductor of the G2496 train of the Hohhot Bureau of the National Railway, introduced that due to the continuous peak of passenger flow during the Spring Festival travel rush, some passengers who purchase seats without tickets can judge whether they can temporarily find a seat or sit down forever after getting on the train based on the color of the indicator lights on their seats. However, it is necessary to remind all passengers that railway tickets are sold dynamically. The ticketing system will adjust the color change of the indicator light according to each operation such as change, refund, and booking. Therefore, the indicator light may change from green light to yellow light and then red light.

For passengers who buy seats without seat tickets, these green lights can be reissued by the conductor through a handheld terminal. It turns out that these small lights indicate whether this seat is for sale. Train staff and passengers can obtain the use of seats at each station along the train in real time based on this.
