Sir Kerala is a big state and there are 'n' number of persons travelling from MAS to diffrent stations in kerala , and have only 3 daily night trains to south kerala and 2 night trains to Malabar. to CBE there are Cheran and Blue Mountain and Now 16041/42 & TVC superfast also stops at cbe and 12601/02 stops at PTJ . Then whats the need of superfast which has a non stop run of aroun 3hrs to stop at CBE. for 16527/28 i agree the diversion.
