If we break TVC-NDLS via DD in two parts: TVC-PUNE & PUNE NDLS, it do have options, especially PUNE-NDLS do have lot many options!!
If we talk about end to end, there exist not many takers, as ERS-NZM DRNTO dont get filled in non-peak season!!
Yes, if via Hubli, it can add extra option for both TVC-BGM/KOP etc!!
