What are the five types of signal lights on the railway There are several types of signal lights on

The color of the railway signal is red, yellow, green, white and blue.

White: Shunting signal, indicating that shunting is allowed through this signal.

Blue: Shunting signal, indicating that shunting through this signal is not allowed. Railway signals are divided into visual signals and auditory signals.

Visual signals are divided into daytime. Nighttime and day-night universal signals. Only nighttime or day-night signals are used in the tunnel.

Visual signals include signals, signal displays, signal signs, hand signals, and locomotive signals. The signal is divided into arm plate signal and color light signal, there are incoming signal, outbound signal, passing signal, blocking signal, warning signal, shunting signal, hump signal, approach signal, and repeat signal.

1. Pit stop signal: green light means that you can pass in the positive line; A yellow light.

Indicates parking on the right line; Two yellow lights indicate a stop at the side line. The red light awareness is not allowed to be crossed.

2. Outbound signal: A green light means that the train is allowed to depart. Two green lights in the auto-block section indicate going to the non-auto-block section, and in the semi-auto-block section, they are going to the secondary line.

A yellow light means that the train is allowed to depart from the station, but at least one block is free in front of the operation. A red light means that you are not allowed to cross it.

3. Through the signal: a green light indicates that the train is allowed to run at the specified speed, and at least two blocked partitions are idle in front of the operation. A yellow light asks the train to pay attention to the running speed, indicating that only one block is free in front of the operation.

A red light means that the train should stop in front of that signal.

Railway Signal Light Product Introduction.

The way in which railway signal lights replace the way employees ride horses to guide the train in front of them has played a great role in railway instructions and has been used to this day. The railway signal light adopts a parabolic reflective system, which has the characteristics of concentrating light and long display distance.

The color changing system combined with the spherical color chip and the cogging trigger mechanism is selected, and the trigger is flexible and accurate, and has the function of preventing "false display". The upper and lower isolation can reduce the corrosion of the reflector and the operating mechanism by acid gas. It is also equipped with a secondary bulb in case of emergency.

Railway signal light product parameters.

Cylindrical battery and three dry batteries are used for power supply) Material: reasonable plastic structure, pure chromaticity, flexible color-changing mechanism, display distance greater than 1250m Applicable temperature: -40 50; The life of the color-changing mechanism is greater than 21,000 times; The light colors (red, yellow, green) are all in the preferred area of the chromaticity coordinate diagram of the hand signal light; The weight of the whole machine (with battery) is less.

Railroad signals.

It is divided into visual signals and auditory signals.

Visual signals are divided into daytime. Nighttime and day-night universal signals. Only nighttime or day-night signals are used in the tunnel. Visual signals include signals, signal displays, signal signs, hand signals, and locomotive signals.

The signal is divided into arm plate signal and color light signal, there are incoming signal, outbound signal, passing signal, blocking signal, warning signal, shunting signal, hump signal, approach signal, and repeat signal.

The following is a brief description of the three display section color light signals.

Pit stop signal: Green light: Positive line passing. A yellow light: stop on the right line. Two yellow lights: enter the side line to stop. Red light: Do not cross. A red light and a white light for a month: Guided pit stops.

Outbound signal: A green light: permission to depart.

Yellow light: Trains are allowed to depart from the station, indicating that at least one block is free in front of the operation. Red light:

Do not cross over. Two green lights: the auto-block section indicates the non-auto-block section, and the semi-auto-block section indicates the secondary line.

When it doubles as a shunting signal, a month of white light: permission is allowed to cross the shunting of the signal.

Passing through the signal: a green light: allows the train to run at the specified speed, indicating that at least two blocked sections are free in front of the run.

A yellow light: Asks the train to pay attention to the operation, indicating that there is a block in front of the operation that is free. A red light:

The train should stop in front of this signal. The passing signal equipped with a permissible signal shows a blue light: the train is allowed to pass at a speed not exceeding 20 km/h without stopping at a red light through the signal, running until the next passing signal, and ready to stop at any time.

Block Signal: A red light: Trains are not allowed to cross the signal. When the light is not on, it has no signal effect.

Advance Signal: A green light: indicates that the main signal is open. A yellow light: indicates that the main signal is off.

Shunting signal: one month white light: permission to cross the signal shunting. A blue light: no permission to cross the signal shunting.

Hump signal: a green light: allows the rolling stock to advance towards the hump at a specified speed.

A green flashing light: instructs the rolling stock to accelerate towards the hump. A yellow flashing light:

Instruct the rolling stock to slow down and advance towards the hump. A red light: The rolling stock is not allowed to cross the signal or to instruct the rolling stock to stop working.

A red flashing light: indicates that the rolling stock is retreating from the hump. A month of white light:

Indicate the locomotive to the bottom of the peak. One month white flashing lights: instruct rolling stock to go to the no-slip line.

Railway signals have different meanings in different contexts

To put it simply, the three colors of red, yellow and green are the same as the road.

Blue indicates that it is not allowed to cross.

There is also purple pink.

It can be seen at the turnout.

Indicates whether the track state is straight or sideways.

White is allowed to pass through the traffic light, and blue is not allowed to pass through the signal light.

The color of the railway signal is red, yellow, green, white and blue, and the purple you say should be blue.

White: Shunting signal, indicating that shunting is allowed through this signal.

Blue: Shunting signal, indicating that shunting through this signal is not allowed.

International law and the construction of national parks are felt.

Railway signal lights come in red, yellow, green, blue, and white. Red, yellow, and green are driving signals; Blue and white are shunting signals. Red means that the signal cannot be crossed; Yellow means pay attention to deceleration; Green means driving at a specified speed; Blue means that the train of shunting operation is prohibited from crossing the signal; White means that the train of shunting operation can cross the signal.

Yellow light: Trains are allowed to depart from the station, indicating that at least one block is free in front of the operation.

Railway signals are usually displayed with different colors, lights, etc., and our country stipulates that red, yellow and green are used as the basic colors of the signal, and moon white, blue, etc. are used as the auxiliary colors of the signal. The meaning of the three basic colors is: red - parking; Yellow – pay attention or slow down; Green—Operates at a specified speed.

1. White: It means that shunting through the signal is allowed.

2. Blue: It means that shunting through the signal is not allowed.

3. Yellow: It means that the main signal is off.

4. Red: The train is not allowed to cross the signal.

5. Green: Rolling stock is allowed to move forward at the specified speed.

Signal light: Road traffic signal light is a category of traffic safety products, which is an important tool to strengthen road traffic management, reduce the occurrence of traffic accidents, improve the efficiency of road use, and improve traffic conditions. It is suitable for intersections, such as intersections and T-shapes, and is controlled by the road traffic signal controller to guide vehicles and pedestrians to pass safely and orderly.

Railway signal lightsRailway signals are divided into visual signals and auditory signals, which can be said to be colorful and colorful. They are orders that indicate the operation of the train and the shunting operation, and the personnel concerned must strictly implement it.
