I guess it's a general knowledge question.
China is located in the northern hemisphere, the train is affected by the geostrophic deflection force in the driving, so the pressure on the right rail is greater than the pressure on the left rail, the ordinary monorail often has the opposite direction of the train, the left and right are just the opposite, the result is that the wear of the two tracks is almost the same Due to the influence of the development history of the train, the industry signals used by the dispatcher to direct the train to start, stop, allow and not to enter the station are all located on the left side of the road in the direction of the train, so the double-track train is on the left side of the train due to the ground deflection force pointing to the right side of the movement, And the geostrophic deflection force of the train that goes to the left on the double-track railway is all pointed inward The mass of a train is assumed, the speed is 20m s, and the latitude of the train location is 45 °, then the magnitude of the horizontal component of the geostrophic deflection force is.
FC level = 2mv sin 45 ° =
This is only equivalent to two ten-thousandths of the weight of the train, and the magnitude is only a few percent of the resistance of the train, and the effect of such a force can only be manifested as the wear of the right rail, and will not make the two trains traveling in the opposite direction on the double line collide
Other claims.

I see: it's the left row. In 1979, I rode on the front of a steam locomotive, with the driver's seat on the left and the signaling devices on the road on the left. When turning right, the co-driver sitting on the right side of the car looked, and the stoker also helped when the weather was bad.
This rule may have been passed down from the left-hand countries of the United Kingdom.
-
This is when the quality is tested.
-
Left row. It has to do with the rotation of the Earth.
In this way, when two trains meet, they will be repulsive and will not attract each other and collide.

German trains run on the right.
There has been a war on the Haizi railway network on this problem, one group believes that the earth is stressed, and the other group believes that it is because the country of origin of the railway, Britain, is on the left, and China has followed suit...

The first question: China's railways were first built by the British, and British trains, horse-drawn carriages, automobiles, etc. all run on the left. It is said that the British designed this way because of the Coriolis force (the left side caused the Coriolis force to be squeezed on the inside to protect the roadbed) and the horseback riding habits during the war (the heart is on the left and right to meet the enemy and protect themselves); The signaling system is set on the left side of the railway, and the driver is on the left, which is convenient for the driver to observe the signal.
The second question: China's cars first learned from Britain to drive on the left, and only after the victory of the Anti-Japanese War in 1946 did they follow the United States to drive on the right. It is said that in an emergency, most people will subconsciously turn the steering wheel to the right and drive on the right side of the road, which will reduce the danger.
-
In the early days, railways in the mainland were designed and built by British engineers, so they all drove on the left-hand side.
-
Since the railway entered China, it has been going left, and it has formed a fixed situation, and all ground signal indications are on the driver's side on the left, and it is difficult to change again. The subway is a new thing in China, and it is customary to drive on the right side of the road traffic habit.

Professional attire, high heels, be more formal!

During the Japanese occupation, Taiwan's railway system was quite mature.
It would be too expensive to change the entire system if it were to be replaced.
In addition, in the early days of Taiwan's recovery, there was not so much thought to change or operate Taiwan. And everyone is used to it.
Vehicles in Hong Kong are still driving on the right and left.
-
Following the tradition, there is nothing to talk about this, and it is very expensive to get it back, so there is no need.
-
It's just a convention, it has nothing to do with the rotation of the earth, and some popular science books are really misleading, and China really needs an anti-pseudo fighter like Sima Nan.
-
The earliest origin is that horse-drawn carriages in Europe drive on the left, and trains were invented by the British, so it is customary!
-
Another advantage is that when Chinese walk, they are used to walking on the right, and when they walk on the iron, they are walking in the direction of the train, or the train does not know how to die from behind

First of all, whether it is north-south or east-west, horizontally moving objects in the northern hemisphere are offset to the left. This is the basic law of geostrophic deflection (usually explained by geostrophic deflection force, but it is actually an inertial phenomenon).
I won't explain the exact reason here, but the hint is similar to the movement of objects in the car when the car turns.
But this deflection is not large, and even cars have no noticeable effect, let alone trains on the tracks.
Perhaps, though
When two trains pass opposite each other, the air flow in the middle is fast, the pressure decreases, and the train will be affected by the outside air pressure, and there is a tendency to tilt inward.
This trend is superimposed on geostrophic deflection???

** In the Netherlands or the UK. Their cars and trains all run on the left-hand side.
And the earliest origin is the carriage driven by people"Driver"It's on the left.
