Operational reasons also places a vital role in change of the train TT FYI. When The opposite zone shows 0% interest in taking it's PM, it's obviously the operating zone's work, since it's daily conversion the train was never independent. 1 year when NS HYB exp is extended till LPI sabari was operated by HYB with 4 rakes where the rake has the lay-over of 23hrs for PM and 12 hrs lay-over at TVC. Then the train was short terminated to SC to save one rake. Now ya it's the time to atleast set it's TT now with this new terminal.
As...
more... you said it's ridiculous to put a proposal to SR to Serve TN the train which was introduced for Kerala must be convenient for KL travelers itself its none of their business weather the train is serving TN or not, the train which was introduced for the pilgrims who are traveling to sabari and Kerala is the ultimate intention of the train
Summer season Kerala travelers
From October till Complete Karthika Masam till Jan 3rd week sabari pilgrims
In fact the new TT is also designed in a way to benifit the travelers and pilgrims, I'm here not against any zone or anything, this train requires some justice that's it all the DRUCC and ZRUCC of SCR had planned accordingly with all the corridor blocks and The TT is designed, as this prestigious train need to be bought to Home division even while LHB conversation as it's maintenance is always been in the 3rd party division.
