Why do cars go on the right in China, why do trains go left?

We found that cars on the road all drive on the right, and trains travel on the left, because this was the case when the train was invented in the earliest days, and when the train was invented, it drove on the leftOf course, taking into account the realistic conditions, because in the northern hemisphere they all drive on the left. <>

The northern hemisphere and the southern hemisphere are all part of the earth, and when the earth rotates, it will produce an outward force, and this outward force will make the train unstable, and the train will just offset this force when it runs on the left side of the northern hemisphere, and when the two trains meet, because they are running fast with each other, they will quickly produce a middle attraction of this force, if they do not drive on the left, it will cause this force to intensify, and if they drive on the left, it will be just offsetTherefore, the two trains can also be more stable when they meet, and can avoid the wear and tear of the railway track when running at high speeds. <>

Our train now runs on the left side is a continuation of the historical tradition, why the train runs on the left, in fact, there is not much thought, because the earliest railway construction in our country was actually built by the British, at that time our construction technology on the railway was still relatively backward, mainly foreign forces in our country to build railways, in some concessions, in order to facilitate the transportation of Chinese raw materials, transported to their countries, plundered Chinese resources, built railways, and then drove on the left, Later, we gradually strengthened and defeated foreign invadersThe land of the world was recaptured, but the habit of trains running on the left side of the road was not fundamentally changed. <>

Trains travel on the left, which can be understood as a habit, because trains in the northern hemisphere basically run on the left, and when you drive on the left, you can just offset the attraction generated when two trains meet, and then you can also lower the track appropriately, and the wear and tear in the southern hemisphere is just the oppositeThe Southern Hemisphere is basically driven on the right, because the Northern Hemisphere and the Southern Hemisphere are subjected to opposite forces when the Earth rotates.

Chinese cars drive on the right, so why do trains run on the left?

Because the train was initially signaled on the left, trains in China run to the left.

Because the trajectory of the train is to the left, and it is an arc-shaped track, it is said that the train should run to the left, and if it goes to the right, the train will overturn.

Because the earliest trains in China were built by the British, the British have been planning railways by driving on the left.

You're not right. The railway in our country is on the right side as the direction of progress. When you say up and down, you actually mean the direction in which the train is running.

The direction from south to north or from west to east is called the upward direction such as: g6012 g1378 anyway, it is called the downward direction such as: g6203 g1375.

However, for trains departing or ending in Beijing, it is different, the direction of entering Beijing is upward, and the direction of leaving Beijing is down, such as: Z98 G79

The Chinese railways were brought by the British, so the habit of driving on the left side continued.

Because the British invented the train to drive on the left, the fundamental reason is the Coriolis force. In the Northern Hemisphere, moving objects are subjected to a force that is directed in one direction to the right, which was later called the Coriolis force.

China's railway system mostly runs on the left, mainly for historical reasons. Many of China's early railways were built by British engineers, while British railways were left-hand and were used here in China.

Britain was the first in the world to realize the industrial revolution, and the train was also invented by the British, because they were used to driving on the left, so the train naturally ran on the left, and all the railways in China at that time were built by the British.

Until the founding of the People's Republic of China in 1949, more than 20,000 kilometers of railways had been accumulated, and if the direction of travel was completely changed, it would be an extremely huge project, and there was no energy and strength to toss at that time. So it has been used ever since.

The northern and southern hemispheres of the Earth will be subject to geostrophic deflection forces, and the forces of the northern hemisphere on the right side will be greater, especially for heavy objects. Therefore, in order to prevent damage to the outside of the roadbed and the overturning of the ** car, the train can drive on the left. This is a reason, but the main one is a matter of habit, the first point.

The most important machine in human history, called the steam locomotive in the early days, had an independent track to travel. Railway trains can be divided into freight cars and passenger cars according to the load, and there are also mixed passenger and freight vehicles together.

In 1804, the world's first steam locomotive was built by the British mine technician De Ivesk using Watt's steam engine, with a speed of 5 to 6 kilometers per hour. Because coal or firewood was used as fuel at that time, people called it "train", and it has been used to this day. On February 22, 1840, the world's first train actually ran on rails, designed by Charles Rivisick, an engineer from Conwall.

The old streets were called in the morning and dusk, and they were replaced by police walkers. Enter from the left with the drum city gate, and exit from the right, all of which are Zhou Fa. "After the Opium War, China was invaded by foreign powers many times, and road traffic was also affected by Britain, Japan and other countries.

Before 1946, China's automobiles and various rickshaws and animal-powered vehicles were driven on the left side for a long time. During the War of Resistance Against Japanese Aggression, the Japanese invaders imposed a blockade on China, and there were very few imported cars, and the original cars were gradually dilapidated and reduced. After the victory of the Anti-Japanese War, a large number of American cars were imported, and their steering wheels and lights were suitable for the habit of American vehicles driving on the right.

But what is the reason why double-track trains in our country run on the left? X0d X0a science tells us that the Earth is an irregular sphere with slightly flattened poles, and that it rotates from west to east, with a linear velocity of about 460 meters per second near the equator, and the velocity of the axes of the north and south poles is almost equal to zero. Our country is located in the northern hemisphere, when two trains meet, the train goes to the left, the train on the west track is subjected to the west, and the train on the east track is to the east, because they are both stressed to the outside, the trains will not collide.

Conversely, if the train goes to the right, the force on the train on the west track is eastward, and the force on the east track is westward, and the force on the train is inward, and the risk of collision increases when the two trains meet.

Chinese cars drive on the right, so why do trains run on the left?

There are three reasons for driving on the left: the first is the problem of historical habits, the train invented by the British at the beginning of the year was to walk on the left, so countries have been following the legacy since then, and most of them follow the principle of driving on the left side;

Second, the force is mainly reflected in the impact on the roadbed, that is, the Coriolis force, the left line makes the Coriolis force caused by the extrusion caused by the Coriolis force applied to the inside, not outward, so that the roadbed will not collapse;

Thirdly, the vast majority of signal equipment is located on the left side, so that the driver is on the left side, and the left side is convenient for the driver to observe the signal, and it is convenient to look.

Trains run on the left. There are three reasons why:

Clause. First, the problem of historical habits, the train invented by the British was to go on the left, so since then, countries have been following the legacy, and most of them follow the principle of driving on the left side;

That. Second, the force action, mainly reflected in the impact on the roadbed, is the Coriolis force, the left line makes the Coriolis force caused by the extrusion on the inside, not outward, so that the roadbed will not collapse;

That. 3. The vast majority of signal equipment is located on the left side. In this way, the driver is on the left, and the driving on the left side is convenient for the driver to observe the signal and make it easy to look.
