Agree that SL coaches should not be removed...
But your reason that "railways should work and serve for common people" is not a great assertion here. Why should railways care for common people...do people care for railways back? Do they take proper tickets to board trains in GS or SL coaches? Do they fulfill their duty of passenger? NO
1 day checking happens and railways catch so many ticketless pax and earn money worth of crores. And expect that railways would serve them. That's not fair.
