What is a single machine, coupler, train, train set, underbody and train? How many kinds of trains are there? Find a solution

A single machine with only one locomotive is called a single machine; In the disintegration shunting operation, the slipped bicycles and train sets are called hook cars; Several cars going to the same place are connected at a time, which is called a train group; The grouped trucks are connected in a row and handed over to the train; The passenger train is called the underbody, not the train.

When the locomotive is hung on the train or under the train, the train is called a train. It has proper train signs (headlights and taillights) and train staff. Single-machine, bullet trains and heavy-haul rail cars should be treated as trains, although they are not fully qualified for trains. ?

Trains are classified and graded according to the nature and use of transportation: passenger trains, mixed trains, military trains, freight trains and road trains. However, priority should be given to trains that go to the scene of the accident for rescue, emergency repair and rescue. Specially designated train classes shall be determined at the time of designation.

Extended data:

A train of railway vehicles runs according to the specified conditions, weight and length, and is equipped with traction locomotives and crew members, as well as train signs. Trains are divided into passenger trains for transporting passengers, freight trains for transporting goods and mixed passenger and freight trains, as well as military and rescue trains with specific functions.

Passenger trains are divided into T-prefix express trains, D-prefix express trains, K-prefix express trains and ordinary passenger cars. Freight trains are divided into through trains, section trains and pick-up trains.

Trains run according to the train operation diagram, which specifies the sequence of the sections occupied by the train, the arrival, departure and passing time of the train at each station, the running time in the section, the stopping time at the station, and the weight and length of the train.

In order to ensure traffic safety, improve transportation efficiency, improve the working conditions of drivers and passengers, save labor, and realize the level of operation and management, we strive to automate train operation. It mainly includes automatic train stop, automatic train control and automatic train operation. With the development of railway transportation technology, the content and level of train operation automation are also increasing and improving.
