When you are catching a car

What is the motor vehicle driver doing?

Come

Give everyone a secret today

01

When stopping in the station

What is the motorcycle driver doing?

In just a few minutes to stop at the station, the driver needs to complete many tasks: confirm the location of the platform → open the door → confirm the arrival time of the train → confirm each display signal Each instrument parameters → confirm the time ... After all the processes are completed, you can drive.

02

When the vehicle arrives at the station

Who opened the door?

In the few minutes of parking, the motorcycle driver is also responsible for the switching of the carriage door. EMU trains are different from the switching door of ordinary buses. EMUs are opened and closed by drivers by driver operation, and ordinary buses are responsible for opening and closing the door by train flight attendants.

Only when the driver dials the control key to "allowed", the door switch indicator light will light up. At this time, the train flight attendant can operate the button to turn on or close the door.

03

When the train is running,

How does the curve turn?

Passengers seemed to be able to feel the turning of a motorcycle in the carriage, but in actual operation, motors often encounter some growing curves. Although the EMU does not have a steering wheel, there is a steering rack. The steering gear can rotate relative to the car body. It guides the EMU to run along the track and successfully pass the curve area smoothly.

04

When the train is running,

Why not light up day and night?

During the day, the train on the platform is also on the light, and it is often on during the operation. Why? On the one hand, because the EMU often travels through the tunnel during operation, it may also encounter extreme weather. The lighting is to ensure that the driver can clearly see the situation in front of the line; on the other hand Lights can be more safely and effectively reminded to keep a safe distance from the train.

05

When the vehicle arrives at the station

Why can you stop in front of the landmark accurately?

The reason why the EMU can stop is so accurate, thanks to the driver's diligence and hard work. In order to realize the high requirements of "zero -pairing and control errors not exceeding 5 cm", the driver must go to the platform after each parking, and take several floor bricks to measure the distance between the braking point and the platform.
