What does the train whistle mean, and what do the various horn sounds of the train mean?

A long sound: 1, when the train starts or the rolling stock advances (when the double engine traction or the use of the repair machine, after the locomotive whistles, the repair machine shall, the locomotive starts after a long whistle) 2, close to the station, whistle mark, curve, crossing, bridge, tunnel, pedestrian, construction site, yellow signal, guidance signal, permissible signal or bad weather 3, automatic block section, through the signal before the stop, can continue to run, notify the operation of the long time 4, the electric locomotive in the maintenance and maintenance, When preparing to lower or raise the pantograph;

2. Long sound: when trains, rolling stock, and single machines begin to retreat;

Three long voices: when the protective personnel are asked to withdraw;

One long and one short sound: when the locomotive on the way requires the repair machine to start the steam (the repair machine should be with the same signal);

One long and two short sounds: 1. When the locomotive requires the steam to be replenished (the machine should be repaired with the same signal) 2. The rear of the train is repaired until the end of the repair is used to promote the standard steam time;

One short and one long sound: 1. In the traction of the electric locomotive with two engines, the locomotive driver of the main service finds that the catenary is faulty, and there is a risk of scratching the pantograph, and requires the repair machine to lower the pantograph (the same signal must be used to repair the machine) 2. When the electric locomotive driver finds a hand signal showing the catenary fault on the way, this signal should be sounded;

Two short and one long sound: 1. When the locomotive requires entry and exit 2, when the signal is required to be displayed at the station;

One long and three short sounds: 1. When it is found that there is a bad place on the line that endangers the safety of the train 2. When the train has a major or major accident and other situations that need to be rescued, 3. After the train stops in the section, it cannot run immediately, and the running car commander is notified;

A short sound: 1, when the test brake machine begins to decompress 2, receive the hand signal of the end of the test braking, 3, during the shunting operation, it means that the signal sent by the shunting commander has been accepted;

2. Short sound: 1. When the test brake machine is relieved 2, when the train crew is required to relieve the hand brake machine 3, when the shunting signal is repeated;

Three short sounds: 1. When the train crew is required to tighten the hand brake machine 2. When the local braking is required;

Continuous short sound: When the driver notices (or receives a notification) of an obstacle on the adjacent line and sends an emergency stop signal to the train running on the adjacent line. When the driver of the adjacent train hears such a signal, he should make an emergency stop.

2. When there is a major accident or other rescue situation on the train.

3. When the train cannot run immediately after stopping in the section, notify the running train commander.

9. Test automatic (a short sound).

Timing of use: 1. When the test brake starts to decompress.

3. During the shunting operation, it means that the hand signal sent by the shunting commander has been accepted.

The train horn is the same as the car horn, it is for safety reasons, the train signal is divided into visual signals, auditory signals, train control system signals, etc., they are the command of train operation and operation, and the train horn is an auditory signal. There are rules for train horns, unlike cars that honk whenever they want. According to railway regulations, trains need a whistle when starting, entering and exiting the station, curves, bridges, tunnels, curves, pedestrians, construction sites, bad weather, etc.

At present, train horns are mainly divided into bagpipes.

Two kinds of horns, bagpipes refer to the sound device that produces a sound through air compression and is used for locomotive and motor train communication and warning. The electric whistle refers to the electric drive audio equipment used for locomotives (rail cars) and bullet trains to communicate and alarm.

Article 359 of the Regulations of the People's Republic of China on the Technical Administration of Railways stipulates:

Auditory signals, three seconds for long sounds, one second for short sounds, and one second interval for sound intervals. When repeating the chirp, the interval must be at least 5 seconds. Bagpipes are sounded on all trains and locomotives running in the city, as well as when passenger trains meet on two lines.

It is a steam locomotive that serves as a shunting and a small running train in the vicinity of urban areas and residential areas.

The whistle should be closed, and the specific area should be determined by the railway authority.

OK". There are two main meanings expressed by the train horn:

1. Communication on train operation management, such as the liaison between the station attendant, relevant driving personnel and the train driver, and remind passengers to get off the train within the safety line.

2. The train driver's horn is mainly to prevent the occurrence of traffic accidents and play a role in reminding and warning.

Categories: Life.

Problem description: Short and long.

Analysis: The train whistle is called the "language" of the locomotive.

The stopped train honks a long (3 seconds) whistle to indicate that it is going forward. The running train honks a long sound, indicating that the train is close to the station, bridge, pedestrians, construction sites, etc.; The train whistle is one long and three short sounds - it is an alarm signal that the train needs to rescue the sedan in a major accident or find that there are unsafe factors in front of it; The train whistle is long, indicating that the train is going back; The rushing train made a short and rapid sound of its sails, telling another train that there was a malfunction in front of the adjacent line and that it was in danger.

Risk, stop quickly.

1. When a long whistle sounds, the train starts or the rolling stock advances.

2. Guide the signal, allow the signal or when the weather is bad.

3. Automatic block section, after parking in front of the signal, it can shout to continue to run and notify the operation of Zheng Mu bucket car for a long time.

4. When the electric locomotive is in the process of maintenance and maintenance, and is ready to lower or raise the pantograph.

5. One long and three short sounds, when it is found that there are bad places on the line that endanger driving safety.

6. When a major accident occurs on the train and other situations that require rescue.

7. To sum up, this is the method of shielding the horn of the train.
