Why does the train not stop before the accident -
Friends, 61 people lost their lives due to the train ravage during the Ravana Dahan fair on 19 October 2018 in Amritsar, a similar incident has come out from Aurangabad in Maharashtra, a migrant laborer on the rail tracks here Was trampled by a freight train, this accident occurred near the Jalna railway line in Aurangabad, in which 16 laborers were killed and many other workers were said to be injured. On the Allahabad-Jalna railway line, which happened around 6.30 am on Friday, 08 May 2020, in the viral video of these two accidents, people are raising questions about the speed of the train, but people probably do not know that the driver even wants the train Can't stop because even if the driver applies emergency brake, the train stops 800 to 900 meters away. Let's understand this braking system of Tran -Braking system of train-
Friends, every compartment of the train has an air brake pipe and this air brake has a pressure of five kilograms per square cm. This pressurizes the nylon brake shoe back and forth. As soon as the pressure is reduced, the brake shoe rubs on the wheel and the train stops. Normally once a train stops, about one kilogram per square cm of pressure ends. After the train stops at the station, the pressure is reduced to five kilograms per square cm from the compressor under each compartment and the brake shoe is separated from the wheel and the train starts running.
Signal requirement for train-
When the train has to move and when to stop, it is not only in the hands of the locopilot, it either moves according to the signal, or according to the guard of the car, the locopilot and the guard are the two people who are driving the car. Let's decide to apply the brakes. It is true that it is a relatively easy task to drive a train at a speed of 100 to 150 kilometers per hour, but braking is a very complex task and in such a way that the train stops at the right time.Loco pilots run the train according to the signal. Loco pilots and guards decide to apply brakes in the event of an emergency. In fact, the train is easy to run, stopping it is very complicated. The brakes of the train are applied in such a way that the train stops at the right place. Breaking the signal and going ahead is sure to leave the job. When there is a green signal, Lokpilot trains run at a fixed speed, two yellow light signals appear, he starts reducing the speed of the train. And for this he has two brakes, one for the engine and the other for the entire train, each coach of the train has a brake on the wheel, all of which are connected by brake pipes. The speed of the train is increased from 30 to 40 km per hour when there are two yellow light signals. When there is a yellow signal, the brake is applied to stop the train, as the next signal is supposed to be red. Accordingly, the train is stopped before the red signal pole. Crossing the red signal in the railway is considered serious negligence of Lokpilot and when this happens, investigation is done.
Emergency brake required -
Locopilot can apply emergency brake in every situation in which it is necessary to stop the car immediately. As if something comes in front of the train, there is a defect in the track, there is a defect in the car, anything can be the reason. Emergency brakes in the train are used by the same lever as normal brakes, emergency brakes are applied when the lever is pulled beyond a specified limit.How much does a train run after emergency braking -
If the 24-coach train is moving at a maximum speed of 110 km per hour and if the loco pilot applies the brakes at this speed, the pressure of the air pipe is exhausted and the brake shoe on the wheels rub off. Even then the train stops going 800 to 900 meters in full.In the case of a freight train, the stopping distance depends on how much cargo is loaded in the train, it stops 1100 to 1200 meters when the emergency brake is applied in the goods train.
The braking system of trains like EMU is even better. In addition to the pressure brake, the electro pneumatic braking system also works. These vehicles stop about 600 meters after applying emergency brake.
Why does locopilot not stop the train when something comes in front -
Usually, people, animals, trains suddenly when the train is in front of the loco pilot does not have time to apply emergency brake and the train stops too far even when the emergency brake is applied. In such a situation, the locopilot is unable to apply the emergency brake. And even if the emergency brake is applied, the collision occurs because the speed of the train is very high, so that it stops at 800 to 900 meters.Visibility generally decreases at night time. The locopilot is seen to have only one or two poles within the radius of the train. If there is a danger beyond half a kilometer, the loco pilot will not be able to see it. In such a situation, when that thing suddenly comes to the fore, then even the loco pilot cannot apply the emergency brake.
In such a situation, the horn in the engine is the last hope of locopilot, it keeps playing it continuously and the horn of Demu in Amritsar accident was also ringing during the accident.
What happens when an emergency brake is applied?
The impression that the vehicle derails by applying emergency brake remains in the people, but it does not happen, the train derails only when there is a malfunction in the track or in the vehicle, by applying the emergency brake, the vehicle never derails. The brake is so that the car can be stopped safely in the shortest time when needed. The locopilot should put an emergency brake in every situation in which it Seems more important than
