What's the difference between high-speed rail and passenger dedicated line?

1. Different track types

1. High-speed railway

High-speed railway is referred to as high-speed railway, which refers to the railway with high infrastructure design speed standards and can be used for trains to travel safely and at high speed on the track, and the train operating speed is above 2 km/h.

2. Passenger Dedicated Line

Passenger Dedicated Line, full name passenger train dedicated line railway, referred to as passenger railway or passenger dedicated line for short, refers to a railway system that only operates passenger trains and technical operation trains.

Second, the significance of development is different

1. High-speed rail

1) Stimulates the economy

High-speed rail has played a very important role in promoting the development of industrialization and urbanization in China, prompting the central cities along the high-speed rail and satellite towns to choose a new "layout"-radiating the central cities with high-speed rail and driving the surrounding cities to develop simultaneously.

2) Promoting scientific research

High-speed railways lose more and earn less. From a commercial point of view, high-speed railways are often a financial burden. However, the scientific and technological benefits of high-speed rail are remarkable, which not only promotes the development of railway technology, but also drives the overall leap of a country's electromechanical manufacturing industry level.

2. Passenger Dedicated Lines

The construction of passenger dedicated lines on busy trunk lines can realize the separate transportation of passengers and goods, which can greatly improve the railway transportation capacity and meet the transportation needs of building a well-off society in an all-round way. It is preliminarily predicted that by 22, the demand for railway passenger and cargo transportation will reach 4 billion passengers and 4 billion tons respectively, with an average annual growth rate of 7% and 4%.

the construction of dedicated passenger lines can not only transfer most passenger cars on the existing lines, but also meet the demand of incremental transportation, especially to free up the existing lines' capacity for developing heavy-haul freight transportation, and quickly form a high-speed, large-capacity, safe and smooth transportation channel to meet the growing transportation needs.

3. Different characteristics and advantages

1. High-speed rail

The high-speed railway runs automatically in a fully enclosed environment and has a series of perfect safety guarantee systems, so its safety level is incomparable to any means of transportation.

since the high-speed railway came out 35 years ago, Japan, Germany and France have carried 5 billion passengers. Although there have been major traffic accidents in high-speed railway, the accident rate is much lower than that of civil aviation, which is almost negligible, and it is the safest transportation system.

2. Passenger Dedicated Line

The minimum curve radius is 8m, the maximum curve radius is ≯16m, and the minimum length between straight line and circular curve is generally ≮.8Vmax. The maximum gradient of the section main line is ≯2‰, and the EMU runs ≯3‰.

the section main line is designed with a long slope, and the minimum slope length is generally ≮9m. When the gradient difference between adjacent slopes is ≥1‰, a vertical curve with a radius of ≮25m shall be set. The number of stations is set according to the distribution of large and medium-sized cities, hubs and famous tourist attractions. The number of departure, arrival and departure lines at the passenger station is set according to the need to meet the dense arrival and departure of trains in peak hours.
