, ERN at 19:45 PM, TCR at 21:15 PM , PGT at 22:50 PM and CBE at 23:55 PM , SA at 03:00 AM , and SBC at 06:55 AM (run little after chennai mail)

With PM at SBC SWR or CAPE SR train (with 3 rakes to use) , even if they continue to have RSA with 12633 then it would give sufficient time for 12634 to leave right time from CAPE towards MS with PM at SBC.
