The truth is Kerala requires more intercity type trains.....Vande Bharath can be night trains and can be experimented in Trivandrum - Bangalore and Trivandrum - Chennai route that too via NCJ - TEN......but since doubling of KTYM line is also getting over probably we can see a TVC - MAQ / MAJN Vande Bharath Express which will cover entire kerala....but not sure about its feasibility.....meanwhile Palakkad - Ernakulam / Trivandrum Intercity Express still remains.....
