The inventor of the train was George Stephenson, and in the beginning, the engine of the train was predominantly a steam engine and was also known as a steam train.

After years of development, the steam car was finally invented in 1814 and named the Voyager. It was called a train due to the flames that would constantly come out of the chimney as it moved forward. The main source of power for steam trains is the steam engine, which is costly to operate and has many disadvantages. Thus, with the emergence of the energy revolution, electricity was introduced and the initial steam trains were improved. It was during this period that the German company Siemens Electric successfully launched the first electric train.

However, it should be noted that electric trains cannot carry a lot of weight and have certain speed limitations. Therefore, shortly after the invention of the internal combustion engine, the train was upgraded and officially entered the era of the internal combustion engine.

One of the earliest internal combustion engine trains was the gasoline train invented by Germany. However, the use of gasoline driving was still costly, so it was later changed to diesel trains.

The emergence of trains has brought very great convenience to people's lives, in the initial period was to help with the transportation of goods, reducing a lot of labor losses, now is to make transportation more convenient, trains have the characteristics of fast speed, kinetic energy, small restrictions, not a high danger, is one of the most suitable for travel transportation.

The popularity of trains is one of the landmarks of transportation progress. It has facilitated communication between cities and has reduced a lot of energy consumption, making a considerable contribution to environmental protection, and has also led to the rapid development of tourism, and since the emergence of trains, the mobility of people everywhere has increased dramatically.

Stevenson's invention brought the significance of trains to reality, and it was with him that we abandoned the original traction locomotive, making transportation more flexible and controllable.

We can say that it is because of his efforts that travel is now so easy and convenient, and we should remember his contribution and pay the highest respect to him.

Now trains have changed over a long period and have smoothly entered the era of high-speed rail. Especially the high-speed trains in various countries are running very fast and can reach about 200 km per hour.

The speed of trains, depending on their class, runs at different speeds as well.

1. Cargo train also called a cargo train, is a train made up of vehicles that carry cargo. It runs at a speed of 80-100 kilometers per hour.

2. Commuter train is a railroad passenger train for urban workers, students, and some residents to travel to and from their living and working places. It mainly serves commuter traffic and runs at a speed of about 70 km per hour.

3. The general express train is called general passenger express train, referred to as general express, and the number of trains uses four digits. The running speed of the general express train is 90-110 km per hour, and the maximum running speed is 120 km per hour, and the general express train has more stops.
