Very few tickets are earmarked for premium tatkal quota, which is almost nothing compared to all berths available for that particular train or class. It is used to be conceptualised that common passengers are not going to afford this quota due to " premium ness of fare". Generally it is not filled up and balance of Prem tat quota dispersed in respective class while charting. Log kya soch te hain unki premium tatkal ticket kya normal tatkal me mil jaye. Isi liye uski nam premium hai bhai.
