Driving on the left, the signal is also on the left, why is the train traveling in the opposite dire

As we all know, cars in China are used to drive right-handed, which is in stark contrast to the operating habits of many foreigners. What is more peculiar is that although the cars all drive on the right, all the trains in the country are the opposite. The reason why the train runs on the left side is related to the history of the birth of the train.

The earliest railways in China were built under the guidance of British expertsThis period of history was in the Qing Dynasty, and Britain could be said to be the first country to enter our country during the Qing Dynasty. That's also for this reason, at the beginning of all the traffic rules.

It's all set in accordance with local UK regulations. Knowing that the driver's seat in the UK is always on the left, it is obvious that trains built by British standards and under the guidance of British experts naturally run on the left. Although China had the strength to build its own railways in the later period, after all, the financial resources and manpower were limited, and it was too expensive to carry out large-scale railway changes, so the habit of trains going left has been retained.

The other way to put it isThe left side of the train is related to the operating habits of the British at that time. Of course, the original train was not as convenient as it is now, which also made it very difficult to drive the train at that time. In those days, train drivers operated the train with one hand, and in order to better observe the road conditions, they poked their heads out of the window to check.

After all, the driver is still mostly right-handed, so the right-handed operation, the most comfortable way for the body is naturally to probe to the left. Later, in order to make it easier for drivers to observe, the British simply shifted the signal lights and signal signs to the left, where the trains should have moved on the left.

In summaryWe can see that the reason why the train goes to the left is that it continues the operation and manufacturing methods of the British. Of course, it is also because the original trains all run on the left, like the new high-speed rail bullet train that still continues to travel on the left, otherwise there are left and right on the railway, and there is no way to ensure safety.

The train travels to the left because of the Coriolis force, so that the force acts on the inside test rather than outward, so as to avoid damaging the roadbed.

There is no particular reason for the train to travel on the left, but the previous driving environment was to drive on the left, and it has continued since then. "Railway Technical Management Regulations" stipulates that the signal should be located on the left side of the train running direction or above the center line of the line to which it belongs. If it is necessary to be located on the right side, it must be approved by the Railway Bureau.

The diversity of traffic lights is easy to observe. On railways, it is explained that trains travel on the left side of the road: it is first and foremost a matter of habit for trains to travel on the left, and the British invented trains to travel on the left.

The root cause is the Coriolis force, which causes the Coriolis force to be squeezed inward rather than outward, so that the roadbed does not collapse. In addition, when two cars meet opposite each other, the Coriolis force can compensate for the pressure difference caused by the difference in air velocity. 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 Curtio force.

In the Southern Hemisphere, the opposite is true, with the Curtio forces going in the left direction, which arises from the rotation of the Earth. When the earth rotates, the top of the moving train is tilted to the left, and if the train is driving on the right, the top may be rubbed when the train is wrong, and even cause the train to collide.

The left-hand driving signal is also on the left, and the reason why the train travels in the opposite direction to the car is because the two use different principles and different environments.
