Slack is too much train only has 19 halts and average speed is below 55kph. The only reason its termed as superfast is because of KR which inflates distance by 200kms as per our site it travels around 2200kms and as per official it travels 2400kms thats how IR is cheating us pax. It can easily be speed up more than 2hrs just check how many trains overtake it even M/E trains overtake it.
