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) such as 200 meters, 310 meters etc. are written. Have you ever wondered why in India the altitude 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 know through this article.

In geographical position, the surface of the earth is round, due to which a slight curve occurs on the surface of the earth. 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.

Railway is meant for the guard and driver of the train. Let's understand from the 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, the height of sea level (MSL) is written. Apart from this, it also helps to give an equal 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 to the electrical wires. So you must have understood why 'sea level elevation' or Mean Sea Level, MSL is written on the Indian Railway Station Board and what it means.
