Composition of railway track

Railway track consists of sleepers, rails and connectors.

1, railway

Rails are the basic components of railway tracks, usually consisting of two parallel rails, which are used to support and guide trains. Rail has high durability and compressive strength, and can bear the weight and impact force when the train is running. Rails also have good electrical conductivity and provide power for trains.

2. Track

Rail is a kind of rail, mainly made of steel. Compared with rail, rail has higher strength and durability, and can withstand higher pressure and temperature. Therefore, most modern railway tracks use rails.

3. Relationship

Connection is to fix the rail, rail and sleeper together to form a complete track structure. Connecting parts usually include spikes, splints and bolts, which can ensure the stability and safety of the track. The connection parts need to be operated according to specific technologies and standards to ensure the firmness and durability of the track structure.

Types and characteristics of trains

1, train type

There are many kinds of trains, including passenger trains, freight trains and mixed trains. Passenger trains are mainly used to transport passengers, while freight trains are mainly used to transport goods. In addition, hybrid trains can transport passengers and goods.

2. Train formation

The carriages of a train are usually arranged in a certain order to form a complete train. According to the needs, the train can be composed of different numbers and types of carriages, including passenger carriages, freight carriages, dining car carriages and so on.

3. Characteristics and advantages of trains

The train has high speed and heavy load, which can realize large-scale and efficient transportation. The train also has good comfort and safety, providing passengers with a comfortable ride experience. Trains can also adapt to different terrain and climate conditions, with good adaptability and reliability.

4. The history and development of trains

Since the beginning of19th century, trains have gradually become one of the important means of transportation. With the continuous development and progress of technology, the speed and load of trains are also constantly improving, which provides strong support for transportation in modern society.
