Why do trains have lights on during the day? Here's some knowledge!

Want to know

When you are catching the car

What is the train driver doing?

Come come come

Let me reveal a secret to you today

01

When stopping at a station

What is the train driver doing?

In the short few minutes when the train stops at the station, the driver needs to complete a lot of tasks: confirm the platform location → open the door → confirm the train arrival time → record data → confirm each display signal → set various parameters → wait for passengers to get on the train → close the door → confirm each instrument parameter → confirm the time... Only after all the processes are completed can the train start.

02

When the train arrives at the station

Who opened the car door?

During the few minutes of parking, the train driver is also responsible for opening and closing the carriage doors. The door opening and closing methods of EMU trains are different from those of ordinary passenger cars. The EMU driver operates the door opening and closing buttons to open and close the doors, while the train attendants are responsible for opening and closing the doors of ordinary passenger cars.

Only when the driver turns the control key to "allow" will the door switch indicator light up, and the train attendant can then operate the button to open or close the door.

03

When the train is running,

How do you turn a long curve?

Passengers sitting in the carriage may not feel the train turning, but in actual operation, the train often encounters some long and steep curves. Although the train does not have a steering wheel, it has a bogie, which can rotate relative to the car body to guide the train to run along the track and pass the curve smoothly.

04

When the train is running,

Why not keep the lights on day and night?

During the day, the lights on the trains on the platform are on, and they are always on during operation. Why? On the one hand, because the trains often pass through tunnels and may encounter extreme weather, the lights are on to ensure that the driver can clearly see the line conditions ahead; on the other hand, because light travels faster, the whistle and lights can more safely and effectively remind relevant personnel to keep a safe distance from the train.

05

When the train arrives at the station

Why can it stop accurately in front of the landmark?

The reason why the EMU can stop so accurately is due to the hard work of the driver. In order to achieve the high requirement of "zero alignment and control error of no more than 5 cm", the driver has to go to the platform every time after parking, measure the distance between the braking point and the platform mark by counting floor tiles, and explore the operation plan of accurate alignment.
