Full ER Network needs a revival....in most of its routes the avg speed is quiet less....no use giving latest WAP7 when ur sectional speeds r less and TT of the train is Slow. You r talking about RPH-MLDT, What is the speed of trains in BWN-RPH Section? What is the speed in Sealdah Division routes, HWH-BWN Main line, ASN-Jasidih, everything needs to be reviewed and speeds must be increased of ER trains. Almost all ER trains TT needs to be reviewed and speeded up.
