Best is to depart SUR at 06.30 am, Arrive GDG at 11:50/ 12:00, at UBL 13:05/15 ( can be considered behind Chalukya as involves LR, So can be sandwiched between Chalukya and Jan Shatabdi to make it reach MYS at 21:50 easily by taking Sharavathi slot from ASK. Why the hell are they ruining the TT by making it arrive MYS at 03 AM in midnight and also crawling all the way from SUR to MYS
