What is the difference between a subway and a light rail???????

Difference Between Metro and Light Rail.

At present, urban rail transit can be divided into two systems: subway and light rail. As for the difference between the two, some people believe that the rail transit under the ground is called the subway, and vice versa; Some people also believe that the light rail is the light rail, and the heavy is the subway. Both of these divisions are unscientific.

So what is the difference between the subway and the light rail?

In fact, whether it is a light rail or a subway, it can be built underground, above ground or on a viaduct; Although the rail weight of the subway is generally greater than that of the light rail, in order to enhance the stability of the track, reduce the workload of maintenance and repair, increase the return section and reduce the stray current, the subway and light rail tend to use heavy steel rails. The division between the two should be based on the size of the maximum peak hour passenger flow in one direction. The maximum one-way peak hour passenger flow that the subway can adapt to is 3-60,000 passengers, and the maximum one-way peak hour passenger flow that the light rail can adapt to is 1-30,000 passengers.

The difference between the subway and the light rail designed by this is first manifested in the axle load of the subway is generally greater than 13 tons, and the light rail is less than 13 tons, and secondly, under normal circumstances, the plane curve radius of the subway is not less than 300 meters, and the light rail is generally between 100 meters and 200 meters, in addition, the number of trains of the subway is also more than the light rail, and the vehicle capacity is also more.

There are also different sayings, one is called the subway, and the other is called the light rail

Some people think that what travels below the ground is called a subway, and what travels on the ground elevated is a light rail; There are also people who think that the weight of the rails of the light rail railway is lighter than that of the subway, both of which are wrong. So what is the difference between the subway and the light rail?

In fact, whether it is a light rail or a subway, it can be built underground, above ground or on a viaduct, and the main difference between the two is the difference in the maximum peak hourly passenger flow in one direction. The maximum one-way peak passenger flow of the metro railway is 30,000-60,000 passengers per hour, and the maximum peak passenger flow of the light rail railway is 1-30,000 passengers per hour. There is no difference between the light rail and the subway rails.

Large-capacity subway cars, the general rated capacity of each car is 310 people, the overcapacity is 410 people, and the marshalling adopts 6 cars per train; Medium passenger capacity of light rail railway car, the general rated capacity of 202 people, overcrowding 224 people, marshalling using 2-4 cars per train, light rail railway can be flexible according to the change of terrain and change the running track, some are built on the ground, some drive underground, some are built elevated, with the advantages of investment saving, quick effect, wide range of application, etc.

Resources.

The subway is a high-speed train underground, and the light rail is an above-ground train, and the speed is quite fast because the track is isolated.

The subway is underground, the light rail is above ground, hehe.

As the name suggests, the subway is an underground urban railway.

Light rail is a light urban rail line that travels outdoors.

Actually, it's one kind, just one on the ground and one underground.

First of all, the light rail and the subway are completely different, their main difference is the road section, the general subway runs under the ground, and some places will run on the elevated road, while the light rail often runs on the road. In addition, they differ in terms of transport capacity, weight and size.

The differences between the light rail and the subway are as follows:

1. The weight is different: the axle load of the subway is generally greater than 13 tons, while the light rail is less than 13 tons.

2. The plane curve is different: the radius of the plane curve of the subway is not less than 300 meters, while the light rail is generally between 100 meters and 200 meters.

3. The number of marshalling is different: the number of marshalling of each train of the subway is more than that of the light rail, and the number of vehicles is also more. The metro line has a one-way capacity of 30,000 to 70,000 passengers during peak hours, while the light rail line has a capacity of 10,000 to 20,000 passengers.

4. Different transportation capacity: whether it is light rail or subway, it can be built underground, on the ground or on a viaduct; Although the rail weight of the subway is generally greater than that of the light rail, in order to enhance the stability of the track, reduce the workload of maintenance and repair, increase the return section and reduce the stray current, the subway and light rail tend to use heavy steel rails.

The subway is a type of rail transportation, which generally operates underground, which is also the origin of its name, but sometimes it may be converted to an above-ground or elevated section in order to match the construction environment and consider the construction and operating costs. The metro system is divided into Type A, Type B, and Type LB buses. The subway generally adopts A-type or B-type trains, corresponding to the width of the train of 3 meters and meters, respectively, and uses 5 8-card marshalling trains.

The capacity of the subway is generally relatively large, and it can reach about 3-70,000 passengers in a single hour, and it is also the first choice for many domestic rail transit.

The light rail is a medium-capacity system, with a peak hour capacity of about 1-30,000 passengers. The light rail system is divided into C-type cars and LC-type cars. The light rail generally adopts C-type trains, corresponding to the width of the train in meters, and uses 2 4-car trains.

Type C car, with a width of meters, a carrying capacity of 1-30,000 h, and a general 4-car group.

1. The quality of the rails is different.

Light rail: 50kg m for light rail.

Metro: The metro track is 65kg m.

2. The passenger capacity is different.

Light rail: The number of passengers can be about 1-30,000 people per trip.

Metro: The number of passengers that can be carried in one trip is about 3-60,000 people.

3. The conditions of the cities applying for development are different.

Light rail: The general budget revenue of the local government of the city applying for the construction of light rail is more than 6 billion yuan, the GDP is more than 60 billion yuan, the urban population is more than 1.5 million, and the passenger flow scale of the planned line reaches more than 10,000 people in one-way peak hours.

Metro: The general budget revenue of the local government of the city applying for the construction of the subway is more than 10 billion yuan, the GDP reaches more than 100 billion yuan, the urban population is more than 3 million, and the passenger flow scale of the planned line reaches more than 30,000 people in the one-way peak hour.

4. The length of the plane curve is different.

Light rail: The length of the planar curve is generally between 100 meters and 200 meters.

Metro: The length of the plane curve is not less than 300 meters.

1. The transportation capacity is different

The maximum one-way passenger volume of the subway is 3-70,000 passengers in peak hours, and the maximum one-way passenger volume of the light rail is 1-30,000 passengers.

2. The axle load of the vehicle is different

The axle load of metro cars is generally greater than 13 tons, while that of light rail cars is generally less than 13 tons. In general, the radius of the plane curve of the subway is not less than 300 meters, while the light rail is generally between 100 meters and 200 meters.

3. Different sizes:

The width of the subway car is generally meters, and the width of the light rail car is generally meters.

The difference between light rail and subway is mainly related to these three aspects, and has nothing to do with whether the track is under the ground.

Hope it helps you and I wish you a great day

What is the difference between the subway and the light rail? Today I finally understood that it was too simple for us to think.

Subway is a form of railway transportation, which refers to the urban rail transit system that mainly runs underground, that is, the abbreviation of "underground railway" or "subway". Light rail is an important form of urban rail construction, and it is also the most rapidly developing form of rail transit in the world today. The weight and passenger capacity of the light rail locomotive are smaller than that of ordinary trains, and the weight of the rails used is light, only 50kg per meter, so it is called "light rail".

The light rail in Chengpeilimb City has the advantages of large capacity, fast speed, low pollution, low energy consumption, punctual operation and high safety. Urban light rail and underground railway, urban railway Xinxian and other forms of rail transit constitute the urban rapid rail transit system. It can effectively alleviate the tension between the population and transportation resources, cars and transportation facilities.

As an effective carrier to improve the status quo of urban transportation, light rail has become an important choice for modern metropolises. It greatly facilitates the travel of passengers and enables residents to enjoy a higher quality of life while sliding. Light rail is also more in line with the standards of green transportation, and the construction of large-scale municipal supporting facilities where the track extends is more conducive to comprehensive environmental management.

The subway is generally driven underground.

Light rail is generally elevated on the ground.

The difference between the subway and the light rail is the number of passengers in the carriage! The subway can also be elevated (many urban subways have elevated sections), and the light rail can also be underground (the Chongqing light rail runs underground)! Both belong to the metropolitan rail transit system!

Rail transit vehicles are divided into A, B, C three models, the size of the carriage is different, the passenger capacity is different, the smallest C car can also become a subway (such as Shanghai Line 8), the light rail is generally 2 4 cars C car, A and B car 4 8 cars are the subway!

The subway is below the ground level, and the light rail is above the ground!

Whether it is a "light rail" (full name "light rail transit vehicle") or a "subway", it can be built underground, above ground or on a viaduct, and the main difference between the two is the difference in the maximum peak hourly passenger flow in one direction.

The maximum one-way peak passenger flow of the "subway" railway is 30,000-60,000 passengers per hour, and the maximum one-way peak passenger flow of the "light rail" railway is 1-30,000 passengers.

There is no difference between the light rail and the subway rails.

Large-capacity subway cars, the general rated capacity of each car is 310 people, the overcapacity is 410 people, and the marshalling adopts 6 cars per train; Light rail railway carriage with medium passenger capacity, the general rated passenger capacity is 202 people, overcrowding 224 people, marshalling adopts 2-4 cars per train, light rail railway can flexibly change the running track according to the change of terrain 1, some are built on the ground, some drive underground, some are built elevated, have the advantages of investment province, quick effect, wide range of application.

China refers to "subway" and "light rail" collectively as urban rail transit, which is more standardized in the sense

"Metro" (also known as weighing rail) generally refers to a large passenger capacity, internationally used A-type cars (3 meters wide, 310 passengers per car).

The "light rail" (light rail transit vehicle) has a small passenger capacity, and the internationally used B-type cars (box width meters) and C-type cars (box width meters), each car has about 230 passengers.

The subway and light rail are very common means of transportation, but many passengers do not know the difference between the subway and the light rail.

1.The train formation is not the same. The subway train formation is usually 4 to 10 cars, and the light rail train formation is only 2 to 4 cars.

2.Planar curves have different radii. In general, the radius of the plane curve of the light rail is between 100m and 200m. For subways, the radius of the plane curve is usually not less than 300m.

3.The axle load is different, the light rail bearing is generally less than 13 tons, and the subway axle weight is generally more than 13 tons.

4.The passenger capacity is not the same. Since the subway is a high-capacity system, the capacity will obviously be a little more.

The capacity is about 30,000 to 60,000 passengers per hour during peak periods. Light Rail is a medium-sized transport system that can carry about 10,000 to 30,000 passengers per hour during peak hours.

5.Different models. At present, according to the national standard, there are three main types of urban rail transit trains, namely type A, with a width of 3 meters, type B, meters, type C, and meters. All subway trains are generally A or B type, and all subway trains are basically C type.

6.The concept is different. The full name of the subway is the Underground Railway.

Originally, it was a kind of rail transit that ran underground. However, with the continuous development of rail transit, there are also some lines laid on the underground subway. Light rail is primarily used to represent new rail transit in the United States and Europe.

Chana Sou light actually refers to light load, not rail load and light axle load.

The subway is a kind of fast, large-volume, electrically driven rail transit in the city. Trains run on fully enclosed lines, and most of the lines in the central city are built in underground tunnels. For lines outside the central city, this is usually built on ground or viaducts.

For Taiwan, China, the subway is called MRT.

For a city, light rail is an important form of urban rail construction. The main advantages of building light rail are less pollution, less energy consumption, no traffic jams during driving, safety and stability, and great convenience for passengers. What's more, the mass of light rail is only 50 kilograms per meter of track, so it is called light rail.

The differences between the light rail and the subway are as follows:

1.The number of groups is different. Compared with the number of marshalling between the subway and the light rail, the number of marshalling trains per train in the subway is a little more, with 5 to 8 marshalling trains, and the light rail has 2 to 4 marshalling trains, so the passenger flow carried by the subway will be a little more.

During peak hours, the metro can transport about 30,000 to 60,000 passengers. During peak hours, LRT carries about 10,000 to 30,000 passengers.

2.Different planar curves. In general, the flat smiling curve of the light rail is between 100m and 300m. But for the subway, the plane curve of this section is usually more than 300 meters.

3.The weight is different, and the subway will generally weigh more than 13 tons. But the weight of the light rail is completely different, generally within 13 tons.
