I guess this is a result of lot of other East/South bound trains like Antyodaya ex, PNBE-ERS, SHM-TVC, Gurudeva express etc which were cancelled due to want of rakes due to the cyclone effect. Only 3 daily trains from East-South were running :Coromandel, MAS mail & DHN-ALLp. When all these trains run, the crowd evens out because so many in AC & SL is unprecedented
