Just like recently happened with Navjeevan express and Cheran express, I really wish SER to do the same.
RSA between Coromandal express and Howrah Chennai Mail to be removed , and Coromandal to be provided with LHB rakes whereas for the time being Mail to continue with CBC rakes.
Honestly the maintenance Standards gonna change drastically as Coromandal Gonna then get nearly 24hrs PM at SRC and 12hrs SM at BBQ.
And...
more... Mail gonna get Huge full day time duration for getting maintained at both SRC and BBQ.
