stoppage at Katpadi is not needed to make it further slower and to avoid late arrival schedule at Chennai. Katpadi has Bangalore Chennai Shatabdi which connects Vellore city with Chennai but not Coimbatore, Tiruppur, Erode, Salem. After converting into Shtabdi Chennai Coimbatore Duronto should halt at Salem, Tiruppur and Erode may be added. It should be decided by Railways whether Erode will be added with them or not if operational halt is needed at Erode. .
