First of all ask them to cut down the stops inside kerala the train even stops at Petta when TVC is only 2 kms far from petta, it is like a passenger train when it enters in kerala, Changancherry to Kayamkulam only 37 kms the train has 5 stops including this both station is this a superfast train? About the coaches, if the train is under trivandrum division you have to see all kinds of things inside the coaches.
