Why there is a box filled with sand under the engine of the train, you will be surprised to know!

The train is considered to be the safest mode of travel. Trains are being improved day by day. Along with this, the security of railways is also being increased. A new type of box is being manufactured. In which there will be no harm to the passengers even if there is an accident. The suspension of the train is being improved. So that there is no jerk in the train while the train is running. These protective measures include keeping a box filled with sand near the wheels of the locomotive. Some people may be aware of this. But most people will not know about this sandbox. So let's find out how exactly it works.

Do you know when this sandbox is used? If you do not know then today we are going to tell you about this part of the railway. Railway tracks are made of iron. They are kept smooth so that cars can run smoothly on them. But many times vehicles get into accidents and the possibility of an accident remains.

Helps in the rainy season

During monsoons, the wheels of the car start slipping due to less friction on the road. The same was the condition of railways. Since the track is smooth during monsoon, the train tends to slip at times. There is a danger of derailment if brakes are applied at such a time. At such times this sandbox comes in handy. From this box, sand is poured on the tracks, which increases the friction between the wheels and the tracks and when the brakes are applied, the train stops normally without derailment.

The wheels are prone to skidding and rolling backward, not only because of rain but also because of the extra weight on the train. In such a situation it becomes difficult to pull the train forward. This sand is sprinkled on the tracks of the wheels to strengthen the grip of the wheels. After this, the train starts moving and then the loco pilot smoothly increases its speed. This sand is blown by compressed air. It is controlled by the loco pilot.
