The way things are going on, many trains from MYS will depart before sunrise, thereby depriving MYS public to board these trains. There are regular passengers in Mumbai-MYS route, though may not qualify for an exclusive train.
Instead of running trains on 3 different numbers (2 Chalukya and 1 Sharavathi) between DR-ASK, the terminal can be shifted to CST/LTT and run a 24 coach train with 6-8 coaches to MYS on daily basis.
