11097 was proposed till Kottayam but was rejected by TVC div. At that time the ERS-TVC (via Kottayam) was still single line. As of now KTYM has more pf and also has water filling options so can be explored. 22149/22150 has very little turnaround time in TVC and will have to start at an odd time from TVC in return journey. This was the reason stated by TVC div when the proposal was sent earlier. So only 11097/11098 has a possibility of some extension.
