Why is 'height above sea level' written on the Indian railway station board?
In Indian train, many signs are used for drivers, linemen, guards and other employees so that the operation of the train can be run properly. Let us know about one such rule ('elevation above sea level') in this article.
All of you must have traveled the train at some time and have also visited the railway station while traveling.
Have you ever noticed that there is a board at the railway station, on which the name of the railway station and the height above sea level (Mean Sea Level, MSL) like 200 meters, 310 meters etc. are written.
Have you ever wondered why in India the height above sea level is written on the railway station board, what does it mean, is it written for the information of passengers or is there some other reason. Let us study through this article.
First of all, let's study what is mean by Mean Sea Level.
As we know that the Earth is round, due to which the surface of the Earth is slightly curved.
Therefore, to measure the world from the surface of the earth, a point was needed which was always the same and there was nothing better than the sea.
It can also be said that to measure the same height of the world, scientists need a point which remains the same.
For this, the sea is the best option and it is very easy to calculate the height with the help of MSL.
This is also because the sea level or sea water remains the same. MSL is mostly used in civil engineering to measure the height of a building or place.

Why is 'Mean Sea Level, MSL' written on the Indian Railway Station Board
Does this happen to tell the passengers?
It is not so.
This information is for the guard and driver of the railway train.
Let us understand by example: if the train is going from 200 m sea level (MSL) to 250 m sea level (MSL).
So the driver can easily decide how much torque will be required by the engine to climb this 50 meter climb, that is, how much power will have to be given to the engine. With this, the driver can guess.
Similarly, if this train goes down, then how much friction will the driver have to apply while coming down, or how much speed will the driver need to maintain. To know all this, sea level elevation (MSL) is written.
Apart from this, it also helps to give a height to the electrical wires above the train. So that the electrical wires keep touching the train wires all the time, that is, it helps to maintain the connection with the electric wires.
So you must have understood that why 'sea level elevation' or Mean Sea Level, MSL is written on the Indian Railway Station Board and what does it mean?
