A new AC weekly service can be very useful to Keralites alover India to reach home between NDLS and Trivandrum with route as Delhi Cantt-GGN-RE-AWR-JP-AII-AHMEDABAD-BRC and then follow the same Trivandrum Rajdhani route.
Expect very good patronage between Delhi-Ahmedabad and Ahmedabad-Kerala due to tourist traffic. Infact for Gujaratis the Kerala is a must go destination.
