What is MSL in railway?
The reason for prominently writing the height of the station above sea level termed as Mean Sea Level (MSL) is for the safety of all passengers commuting in Indian Railway trains. With the help of the MSL, a loco-pilot controls the speed of the train.
What is MSL in survey?
Definition. Mean Sea Level (MSL) is the datum for measurement of elevation and altitude. Mean Sea Level is the equipotential surface of the Earth as described by the WGS84 geoid.
What is RL in railway station?
What is RLWL or Remote Location Waiting List? Under remote location waiting list, which is also known as RLWL category of Indian Railways, train tickets are issued to railway passengers for intermediate railway stations (that means between the originating station and the terminating station).
Which point actually represents the mean sea level written at Indian railway stations?
Normally, ‘Mean sea level’ (MSL) is displayed on the station sign at both ends of the platforms. The ‘Mean sea level’ (MSL) is a reference level from which vertical elevation of a place is measured….

How is MSL calculated?
For a period of about 19 years, the MSL has been continuously measured using the rise and fall of the ocean on the seacoasts. The atmospheric pressure and temperature also play a role in the continuous motion of the sea and being able to measure its level. A datum is the easiest way to calculate the MSL.
How is MSL measured?
NASA measures sea level around the globe using satellites. The Jason-3 satellite uses radio waves and other instruments to measure the height of the ocean’s surface – also known as sea level. It does this for the entire Earth every 10 days, studying how global sea level is changing over time.
What unit is MSL?
Mean Sea Level
Mean Sea Level, or MSL, is your true altitude or elevation. It’s the average height above standard sea level where the atmospheric pressure is measured in order to calibrate altitude. On a Sectional Chart, all of the numbers you see that denote altitudes are denoted in MSL, unless they are in parentheses.
What is GNWL and WL?
These are explained below in detail: Waiting List (WL): If the passenger status is marked as WL followed by a number then the passenger has a waitlisted status. Similarly, GNWL/AVAILABLE means that current status of your ticket is CONFIRMED because some passengers who booked before you have cancelled their tickets.
What is the MSL of India?
Mean Sea Level (MSL) adopted by a survey of India for reference is located at Mumbai High. India’s mean elevation is 160 m (525 ft) and is taken from Mumbai High.
What is the full meaning of MSL?
Average height of the surface of the sea for all stages of the tide over a 19-year period. NOTE: when the abbreviation MSL is used in conjunction with a number of feet, it implies altitude above sea level (e.g., 1000 feet MSL).
Why do we use MSL?
Mean Sea Level, or MSL, is your true altitude or elevation. But as the plane increases in altitude, the altimeter reading becomes less accurate. Once the plane reaches transition altitude, the aircraft uses the MSL along with air pressure readings to maintain level flight.
What is mean sea level (MSL) in railway station?
Services of Holiday Special Trains Extended Until July. Here’s Complete List The reason for prominently writing the height of the station above sea level termed as Mean Sea Level (MSL) is for the safety of all passengers commuting in Indian Railway trains.
How does an MSL control the speed of a train?
With the help of the MSL, a loco-pilot controls the speed of the train. The primary reason is that of ensuring safety to passengers. Read more to know how. Have you ever wondered why height above sea level is mentioned on yellow signages at railway stations?
How does an MSL work?
The MSL directly alerts the loco pilots (train drivers) and the guards about the altitude they are travelling at. With the help of the MSL, a loco-pilot controls the speed of the train. If the train is moving towards a higher altitude the loco-pilots provide power according to the engines for the smooth running of trains.
How to find the name of a railway station above sea level?
While trying to find the station’s name, you must have also noticed figures mentioning the height of the station above sea level. The reason for prominently writing the height of the station above sea level termed as Mean Sea Level (MSL) is for the safety of all passengers commuting in Indian Railway trains.
