Wednesday:
22807 AC superfast departs Vijayawada at 14:40 and arrives Chennai at 22:45.
12270 Chennai duronto departs Vijayawada at 14:30 (just 10 minutes ahead of 22808) and arrives Chennai at 20:10 (Whooping 2:35hrs ahead).
12078 Janshatabdi departs Vijayawada at 15:20 (40 minutes later the 22808) and still arrives Chennai at 22:35 (10min ahead of 22808 by overtaking it).
And...
more... on Saturday its the 12434 Chennai Rajdhani which runs on 14:30-20:10 slot.
Why SCR and SR have given 22808 a pathetic time slot between BZA-MAS ? This train can easily arrive MAS by 8:30pm or even by 9pm.
PS: If platform constraints are there, then why can't it be shifted to Chennai Egmore ?
