Had travelled by this train from Palakkad till Ernakulam last week. Departed from Palakkad at 2:20 and reached Ernakulam North at 4:35 After a brief stop of 5 min reached Ernakulam South at 4:45....the speed of the train throughout the journey was awesome. This probably goes to show that trains in Shoranur-ERS stretch can really go at high speeds.Don't know why other trains with the same stops dont travel at such speeds in the same stretch???
