Yes...This was the question which I had as well when I travelled in this train once between ROU-ERS. Surprisingly good crowd boarded at intermediate stations like BZA, Ongole, RU towards ERS as well. Surprisingly no stoppage at Thrissur ( probably the only train in Kerala to not stop). Their used to be 2AC ( 2 coaches) as well which has been discontinued. Hope it is restored. As of now lot of slack from CBE till PGT to allow overtakes of at least 3-4 trains. Reaches on time at ERS.
