Overall a good TT but a few observations:
1) MYS - SBC at around 70 kmph avg is bit high to ask for. I would be happy if the run time between MYS and SBC is around 2.25 hours atleast. 2) A bit of slack is required between ED and TPJ. 3) MDU - VPT timings is unrealistic.
Though your concept is providing a full AC train between SBC and TPJ/ South TN is something to welcome I seriously doubt the patronage for a full AC train with special fare structure, not...
more... to forget that the train runs on a circuitous route. If the existing route be retained then addition of good number of SL coaches is necessary, or if you wish to keep it as a full AC train then the route has to be shortened via SA - NMKL - KRR - DG.
Despite my criticism, I am glad that you have made an imaginary train that is aimed at taking the train travel experience to next level from Bengaluru to Central / South TN. Best wishes!
