Trains starting with c generally refer to:Intercity EMU passenger trains. It is a type of train of Chinese railways that usually starts with the letter "C" and is usually followed by a number such as C1, C2, C3, etc. Intercity EMU trains usually run between two cities and are used to connect major cities within an urban agglomeration, providing a high-speed, convenient mode of transportation.
The train schedule of intercity EMU trains is usually relatively simple, and it is generally represented by the first letter of the city name in pinyin plus a number, for example, the number of Beijing-Tianjin intercity trains is C2001, C2002, etc. In addition, the departure time of intercity EMU trains is usually more dense and the interval is shorter, which is convenient for passengers to travel.
The operating speed of intercity EMU trains is generally about 200 kilometers per hour, and the maximum speed can reach more than 300 kilometers per hour. The carriage is fully equipped, with comfortable seats, air conditioning, power sockets and other facilities to provide passengers with a comfortable riding environment.
The operation mode of intercity EMU trains is also relatively flexible, and the frequency and stops can be adjusted at any time according to the passenger flow situation, which is convenient for passengers to travel. In addition, intercity EMU trains can also be seamlessly connected with subways, buses and other modes of transportation, making it convenient for passengers to travel between cities.
Intercity train design requirements:The design of intercity EMU trains is not simpler than simple high-speed trains, it needs to be compatible with high power, high speed, fast start and stop, large capacity, low energy consumption, light materials, smoothness, comfort, convenience and interoperability and other advantages, seeking the best balance in a variety of factors, is an extension of high-speed rail technology.
Speed Requirements:As an intercity high-speed train or intercity express train, the intercity EMU serves the intercity MRT railway, and has certain requirements for speed. Since the distance between the city centers of different neighboring cities in China is mostly about 50 to 150 kilometers, the mainstream maximum operating speed demand of China's intercity EMUs is 150 km h to 300 km h. Most intercity EMUs are also designed and built with only 200kmh or 250kmh speed standards.
Shift Requirements:The frequency of intercity EMUs is adapted to local conditions, and the roads, stations, quantity, time and fares of intercity EMUs that run every day need to be scientifically planned, reasonably arranged and flexibly designed, and adjusted regularly and in a timely manner. The frequency of intercity EMUs takes into account timeliness, economy, public welfare, adequacy, and covers a large area and multi-level travel population. As a type of high-speed train, intercity EMUs need to operate according to the principle of daytime operation and night maintenance, and must suspend operation when traveling in extremely bad weather or other special safety hazards.
Capacity Requirements:As an intercity train, the intercity EMU will undertake a huge commuter passenger transport function, especially during holidays or peak hours, with a large passenger flow and strong passenger mobility, so the carriage design of the intercity EMU should focus on improving the passenger capacity rather than overemphasizing the ride comfort. Intercity EMUs are grouped according to the standard of 8 carriages, and the maximum number of passengers per train is between 1000 and 2000, and the passenger capacity is increased by EMU reconnection if necessary. The shortest departure interval of intercity EMUs is 3 minutes, and the maximum number of passengers per hour in one direction is about 30,000, and the transportation capacity is between the subway system and the light rail system.
In short, the train starting with C is an intercity EMU train, which is a new type of train that provides high-speed and convenient transportation, which can meet the travel needs of people in the urban agglomeration.
