From some sources in SR , with the existing timings at least in the near future it seems highly unlikely since KCVL is jampacked with morning arrivals. Even with the existing time at ERS the high layover time can easily be reduced if they are able to speed up the train and make it reach ERS by 23:30 hrs. Some slack between JTJ-Salem & between Erode to ERS can be easily reduced. It can arrive around 11:30pm & leave next day morning at 6:50 ( 7 hrs layover)
