Chapter 335 Visual Signals Quick Lights Are Safe
In general, Liu Qun recommends that you buy stainless steel fast food cups with the "304" logo, and at the same time suggest that you buy from larger stores or well-known online shopping malls.

When purchasing, you must choose the stainless steel products of those big brands, and the quality is guaranteed.

Never be cheap. Buying cheap things is just about being comfortable when you buy them.The pain starts after you buy it.

Relatively speaking, for cheap and inferior things, you are only happy for a moment when you buy them, and then there is endless regret and anger;
For those more expensive, high-quality things, only you will feel heartbroken when you buy them, and you will be full of joy and happiness when you use them.

After searching for information, Liu Qun popularized it in the WeChat group of the team - "304" is a general-purpose stainless steel, which is widely used to make equipment and parts that require good comprehensive performance (corrosion resistance and formability) , has strong corrosion resistance.

304 stainless steel is the most widely used chromium-nickel stainless steel. As a widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; it has good hot workability such as stamping and bending, and is suitable for For food processing, storage and transportation.

304 stainless steel also has good processing performance and weldability, and is a nationally recognized food-grade stainless steel.Therefore, the use of 304 stainless steel tableware can prevent the growth of bacteria to the greatest extent and ensure the health of users. The first package of K18 times is a "304" fast food cup and a pair of stainless steel chopsticks.

After eating a well-made bowl of noodles, the train has already entered the F station.

Zhang Lan got off at the door of the soft sleeper compartment, and after handing over to the passenger on duty at station F, she walked towards the rear of the train. She stopped at station F for a long time, enough to remove the track inspection car.

Zhang Lan came to the scene where the train was being unhooked, turned on the video recorder, and recorded the unhooking process. The train inspector "Two Five" was also here.

He is responsible for following the command of the station and picking up the train.

Seeing Zhang Lan taking pictures of him, he also made a victory gesture to Zhang Lan, saying: "Zhang Che, this is the work of our vehicles, it has nothing to do with your passenger transportation, besides, it's all about familiarity, it's too simple It’s my job, it’s not difficult at all.”

"Second Five" also felt that it was not difficult to take off the track inspection car.

Everything is going on in an orderly manner.

Zhang Lan’s walkie-talkie sounded the call of the train attendant, informing Zhang Lan that the station-car interactive system at Station F showed that there was a passenger with a ticket to report the loss of a replacement ticket, and asked the train conductor to come to the office for assistance.

Seeing that the shunting machine that had been waiting there for a long time was about to drag the track inspection car into the corresponding line after being connected.Zhang Lan told the porter again—be sure to lock the car door.

Then I went to the hard-seat carriage, ready to see the situation of the train attendant's report of loss and replacement.

When the train starts slowly.Zhang Lan was already standing in the train compartment where the office seats were located, preparing to compile passenger records.

After about a minute or so, the voice of the inspector "Twenty-five" suddenly sounded on the intercom: "The chapter car is not good, the taillights at the end of the row are not upside down, and they are still hanging on the tail of the track inspection car. Now we don't have taillights at the rear."

The tail light at the end of the passenger train has two sides, one side is a white light, facing the direction of the locomotive, and the other side is a red light, facing the rear of the train, during accidental stops, stops in stations and normal operation of passenger trains , a red light toward the rear indicates that it is listed to prevent rear-end collisions.

This kind of light is not used for lighting, but as the tail light of a train, only passenger cars have it.

The white light facing forward is for the station attendant to observe. When the attendant observes the white light on the front and the red light on the back, he can confirm that the entire train formation is complete. If the tail light is not seen, then it is very likely. It's a big problem.

In the past, the signalmen along the line had to look at the taillights of the train when the train passed, indicating that the train was complete. If there was no taillight, it would immediately send a message to the next signal building that "the train passed according to the signal, but there was no taillight." "At the same time, it will report to the dispatching system, block the rear section, and send a message to the upper signal building that the train may be lost, warning them not to let the train enter the blocked section.

It means that it is very likely that the train will be decoupled and lost while running.Of course, this is only a theoretical statement, and this situation has not happened in reality, but the role of the taillights can also be seen.

Passenger trains in our country have red lights and are designed to be detachable. The installation position is that the front and rear doors are staggered except for luggage carts, postal cars, and generator cars, which are installed side by side at one end.

But foreign railways, many countries have adopted fixed taillights, and two red lights are respectively installed at the front and rear ends of passenger cars.

Careful passengers will find that when traveling by train, standing on the platform and waiting for the train to come, or standing on some overpasses and watching the train rumbling past, there is a question, that is, do not know Why?No matter day or night, the lights of the moving trains are on.

This is different from our car lights. Why are the train lights on during the day?

In fact, railway signals are divided into visual and auditory signals. That is to say, the relationship with lightning and thunder is the same. We often hear the rumbling thunder after a few seconds after seeing the lightning.

The speed of the train is very fast in operation, just like lightning, the speed of the lights is faster than the sound, so the lit light signal can better remind the staff on the platform and along the line to pay attention to avoiding the incoming trains , At the same time, it also reminds the platform staff to restrain the behavior of passengers, so as to prevent passengers from stepping outside the safety white line, which will cause bad results.There is also a kind of notification to the train that is coming to the subject, so as to remind each other that the train is coming and will meet, and at the same time, the siren must be sounded for warning.

Also, there are tunnels on some lines, and there may even be bad visibility such as wind and rain during driving.

We all know that due to the heavy weight and high speed of the train, it is more difficult to brake suddenly.Turn on the lights and honk the horn when going through curves and going up and down slopes, just to ensure safety.

In recent years, trains seldom whistle after entering urban areas. This is to reduce noise pollution and provide a quiet environment for people living in urban areas.

Therefore, the light replaces the original whistle and plays the role of notification and avoidance, just like when we are driving a car, sometimes we turn on the lights to remind the target vehicle or when the weather is bad.
