How Can Trains Go Uphill on Smooth Metal?

Although it may seem contrary to the laws of physics at first glance, of course there is something behind it. logical explanations was.

How come giant machines have so much? heavy loads and we examine whether they can pull themselves uphill.

Harmony of physics and engineering

The secret of trains going uphill is basic physics principles and lies in a combination of advanced engineering techniques. The interaction of trains with the rails is provided by friction force and engine power.

Rails are usually made of steel, and since train wheels are also metal, friction minimally. This low friction makes the movement of trains easier, but requires special solutions to provide sufficient traction when moving uphill.

The importance of friction force

The friction force between the rails and the train wheels is actually the main force that enables the movement of the train. What train wheels do to steel rails pressurecreates sufficient friction force.

However, this friction may not be sufficient in some cases. That’s why specially designed wheel and rail systems are used in trains. For example, some trains have special wheels on wheels. roughening surfaces is available. These surfaces increase the friction force by increasing the contact surface with the rails.

sandblast system

One of the important technologies that enable trains to go uphill is sandblast system. A thin layer of sand is sprayed onto the rails through special nozzles placed in front of the train wheels.

Sand enables the wheels to hold on to the rails better, making the train run better, especially on slippery or wet rails. traction It helps him have it. Thanks to this system, trains can more easily overcome difficult slopes and bad weather conditions.

Engine power and weight distribution

Engines used in modern trains, high torque and power electric motors that can produce These engines provide the extra power the train needs when going uphill. In addition, the weight distribution of trains also plays an important role in this process.

weight of locomotive to the front It loads more and increases the pressure applied by the wheels to the rails. By increasing the friction force, it allows the train to move uphill.

If you feel like you’re going back when you get on the train, now you know the secrets behind it. So you can enjoy your journey.
