A brief introduction to China s railway system?

The Railway Bureau is the administrative body under the jurisdiction of the Ministry of Railways. Each bureau is divided by region, including Nanchang, Zhengzhou, Shanghai, Nanning, Wuhan Railway Bureau, and so on. Each office is divided into "segments" according to their working nature.

Organic, vehicle, industrial, electricity, vehicle, domestic water supply, passenger transport, materials, power supply section. The work of each section is different, such as the locomotive depot, which is to manage train drivers; The depot is to manage the operation of the trains; The public works section is to manage the maintenance and maintenance of the train running track (called the track), and the depot is to manage the maintenance and maintenance of the train; The passenger section is to manage the conductors, that is, the staff on the train, etc., as the name suggests.

As for the construction company you are talking about, it should be an engineering company. The railways have now been stripped away.

Top dog.. How can this be explained in a nutshell???

The railways are divided into. One. The Ministry of Railways... There are a lot of institutions.

Two. The railway bureaus directly under the Ministry of Railways. There are a total of eighteen in the country. Zhengzhou. Beijing. Nanchang. Guangzhou Railway. Shanghai. Wuhan. Sian. Taiyuan. Shenyang. Lanzhou...

Three. Railway Engineering Bureau... It is divided into medium railways. and China Railway Construction. . .

Four. Railway Design Institute... Iron one, two, three, four, five courtyards. A total of five design institutes. Five. Railway colleges... The former college directly under the Ministry of Railways.

Southwest Jiaotong University. Beijing Jiaotong University. Central South University (Changsha Railway Institute). Tongji University (Shanghai Railway University). East China Jiaotong University. Lanzhou Jiaotong University. Dalian Jiaotong University...

There are also railway vocational and technical colleges in various provinces and localities. School... To be a dime a dozen..

Tell you. . . Railways are a big system... The railway bureau is not equal to the engineering bureau. It feels like a question to ask. Nothing is known about the railway system.

The railway bureau is the operating unit of the railway and is responsible for the transportation of passengers and goods.

There is no such thing as a railway construction company.

There are five major systems on the railway, car, machine, engineering, electricity, and vehicle. That is, vehicle service, machine maintenance, public works, electrical service, and vehicles. Five segments.

Rail transport is a type of overland transportation in which a locomotive pulls a rolling stock on two parallel railroad tracks. The traditional way is steel wheel travel, but the generalized railway transportation still includes non-steel wheel travel methods such as maglev trains, cable cars, and ropeways, or rail transportation. Rails provide an extremely smooth and rigid medium for the wheels to roll on them with minimal friction, making it more comfortable for the people on it, and it also saves energy.

If properly configured, rail transport can save 5 to 70 percent of energy compared to road transport carrying the same weight. In addition, the rails can evenly distribute the weight of the train, so that the load capacity of the train is greatly increased.

The components of the railway transportation system include: train depot, locomotive depot, public works depot, electrical depot, depot and power supply depot.

1. Train depot.

The train depot is one of the important units of the railway driving system, which is responsible for train operation, train depot management station freight and other businesses, the planning and income of freight and passenger transportation of various large and small stations in the jurisdiction, and the operation monitoring of trains.

2. Maintenance depot.

The locomotive depot is the main driving department of the railway transportation system, which is mainly responsible for the operation, comprehensive maintenance, and overall maintenance (generally medium repair and section repair) of railway locomotives (commonly known as "locomotives").

3. Public Works Section.

The Public Works Section is the grassroots unit of the railway system, responsible for the maintenance and repair of railway lines and bridge and tunnel equipment. Railway patrol and railway crossing guarding are all within the scope of responsibility of the public works section.

4. Electric section.

The electric service section is an important organization of the railway system, which is responsible for the management and maintenance of the normal operation of the ground signal, locomotive signal and turnout of the train during operation.

5. Depot.

The depot is one of the important units of the railway driving system, which is mainly responsible for the operation, maintenance and maintenance of the train's vehicles (excluding the locomotive).

6. a power supply section.

The power supply section is one of the important business departments of the railway system, which is mainly responsible for the traction power supply of electrified railways, the power supply of railway transportation signals, the power of railway areas, and the overhaul and maintenance of power equipment.

Hello, the railway communication system includes the following subsystems: (1) the transmission subsystem provides information transmission and exchange channels for other communication subsystems and signal systems. The system consists of optical digital transmission, bumper core backup and optical fiber loop. (2) Wireless communication.

The subsystem provides a means of communication between fixed users such as dispatchers, station attendants, etc., and mobile users such as train drivers, maintenance, public security, etc., which has a positive impact on driving safety, operational efficiency, and service quality.

Respond to emergencies.

Guarantee is provided. The system is networked with digital trunking devices. (3) Program-controlled**.

Subsystem: A communication subsystem for staff to communicate with internal and external official communications. The system consists of a network of digital program-controlled switches. (4) The digital dedicated dispatching subsystem is a dedicated direct dispatching system set up by train operation dispatching command, power dispatching, disaster prevention and rescue and maintenance departments to provide operation command.

The system consists of a digital dispatching main system, a sub-system, a front desk and an extension. (5) CCTV.

The monitoring subsystem provides visual information about train operation, disaster prevention and relief, and passenger guidance for the dispatchers of the control center, the attendants of each station, and the train drivers. The system is composed of image acquisition, image display and recording, station control, central control, and signal transmission. (6) The broadcasting subsystem is used to inform passengers of subway train operation, safety, guidance and other service information, and issue operation orders and notices to staff.

The system is centrally controlled by equipment, stations and depots.

The broadcasting equipment is composed of Xiaohui and transmission interfaces. (7) The communication power supply is composed of AC power switching and distribution panel, power supply, high-frequency switching power supply and battery pack. (8) Other systems include optical cable and optical fiber monitoring, power environment monitoring, clock and other systems. Hope.
