Why IRCTC doesn't Allow you to choose Seats? You don't believe the Technical Reason Behind This!

Do you Know why  IRCTC does not allow you to choose seats? Would you believe that the technical reason behind this is PHYSICS.

Booking a seat in a train is far more different than booking a seat in a theatre.

Theatre is a hall, whereas train is a moving object. So safety concern is very high in trains.

Indian railways ticket booking software is designed in such a way that it will book tickets in a manner that will distribute the load evenly in a train.

Let me take an example to make things  more clear : Imagine there are sleeper class coaches in a train numbered S1, S2 S3... S10, and in every coach there are 72 seats.

So when some one first books a ticket, software will assign a seat in the middle coach like S5, middle seat numbered between 30-40, and preferably lower berths (Railways first fills the lower berths than upper one so as to achieve low centre of gravity.)

And the software books seats in such a way that all coaches have uniform passenger distribution and seats are filled starting from the middle seats (36) to seats near the gates i.e 1-2 or 71-72 in order from lower berth to upper.

Railways just want to ensure a proper balance that each coach should have for equal load distribution.

That is why when you book a ticket at the last, you are always allotted an upper berth and a seat numbered around 2-3 or 70, except when you are not taking a seat of someone who has cancelled his/her seat.

What if the railways book tickets randomly ? A train is a moving object which moves around at a speed of around 100km/hr on rails.
So there are a lot of forces and mechanics acting on the train.

Just imagine if S1, S2, S3 are completely full and S5, S6 are completely empty and others are partially  full. When the train takes a turn, some coaches face maximum centrifugal force and some minimum, and this creates a high chance of derailment of the train.

This is a very technical aspect, and when brakes are applied there will be different braking forces acting at each of the coaches because of the huge differences in weight of coach, so stability of train becomes an issue again.

I felt that this is a good information worth sharing, as often passengers blame the Railways citing inconvenient seats/ berths allotted to them.

Gol Gumbaz

GOL GUMBAZ

             Gol Gumbaz is the second largest Dome(Gumbaz) structure in the world and Largest Dome in India, which is Unsupporeted By any pillers, This one of Wonders of civil Engineering field so feel to be proud. It is located in Bijapur,Karnataka, India.
If you want This places's Location on Google map Click Here.

Here I am visited so many times, it has beautiful Garden's around the Dome and many trees. And the top view from the terrace of Gumbaz is Awesome the whole Bijapur city will be Seen wonderfully.  😀  so One must visit this Place in their Life.

History:- Gol Gumbaz, the mausoleum of Muhammad Adil Shah (AD 1626 –56) located in Bijapur, District Bijapur, Karnataka State is an important monument of Indo-Islamic architecture aptly known for its amazing dimensions and unique acoustic features. The construction of this building was completed and the deceased king was interred in this building in 1034 AH (AD 1656) and contains the sepulcher containing the tombs of Muhammad Adil Shah (AD 1626-1656), the seventh Sultan of the Adil Shahi dynasty, his wives and daughters. Soon after his accession to the throne in AD 1626, the Sultan started constructing this edifice for burying his mortal remains. He was buried in the vast vault beneath the floor along with other family members. The exact position of the real tomb is indicated by the wooden canopy kept on the high platform at the middle of the floor of the hall.

And this Gumbaz is a fine piece of Islamic architectural style. The Gol Gumbaz has a floor area of 1700 square meter, a height of 51 meter and diameter of 37 meters with 3 meter thick walls. The construction of this large tomb took around 20 years to complete.
Another significant feature of the Gol Gumbaz is its central dome which stands without the support of pillars. Also the central dome of Gol Gumbaz is the second largest dome in the world after the dome of St. Peter's Basilica in Rome.

And At the eighth storey is a broad gallery around the dome which hangs out at around 11 feet. It can be reached by means of a winding staircase in the four towers. It is known as the Whispering gallery(incredible acoustics) as a tenfold echo can be obtained from here. From the base of the dome there is a fine view across the city.

Fact:-A `bijli pathar` is seen hanging over the main entrance which is the south door. It is actually a piece of meteorite which is believed to have fallen during the reign of the Emperor. It is believed that the stone protects the tomb from lightning.

So we can Wonder that In the 17th Century also Without that much of knowledge of Building and construction How they Build this Gumbaz? A massive Hats off Goes to them who was build that Gumbaz.
