After travelling in 12291 on Friday Nov 3 , I would recommend to travel on this train . It might be a weekly train less known compared to 12658 Chennai Mail , but one can't under estimate 12291 . Due to certain operational reasons it departs late from YPR most of the times. But it's still better than 12658 on Friday if it's rescheduled. And SWR does give 12291 a good priority.
