Do you knowwhy the height above sea level is written on the railway station name boards? Here is the answer…. First of all we need to know what is MSI (Mean sea level)……. It gives information about the altitude of the station above the sea level. Train drivers and Guards uses this MSL to control the speed of the train according to the height in which the train is travelling. For example- If a train is moving from station A to station B (where MSL of station B is higher then that of station A), the speed of the train has to be increased and vice-versa. It results in a safe Journey. Reasons – Why the railway stations name boards are coloured in yellow? The letters in the yellow background shine as same as the sun, yellow board is also easily visible instead of other colors even in night, black colour is best visible in yellow background due to which people can read the name from a distance. These boards are placed in the beginning and the end of every platforms in the stations.
