Railways are the biggest mode of transport and are essential for its proper operation. It also has some rules. One such rule is attached to the name of the railway station to be written of its elevation from the sea level. But you know why it is written. The reasons for this are very important. You don't even know about it, so let's know why is elevation from the sea level written at the railway station board.
In fact, the height of the sea level on the board is written because in earlier times scientists needed a point that looked similar to that of the world in a uniform height. The sea was considered perfect because the sea level remains the same and that is why the height of the sea level is written along with the city on the yellow board. It is also necessary and that is why the station has a city name as well as its height.
If a train is moving from 100 m to 200 m in height, the guard or driver read the board and instill in his mind the math of the speed ahead or how much speed of his train is to be put forward. He takes all it to know what the height of the electric wires will be ahead and what will happen on hitting the brakes.
