Scratching down ideas...
- Mumbai to Bagalkot—BCT to UBL (Hubli), UBL to BGK
- Bagalkot to Vellore—BGK to VLR
- Vellore to Pondicherry—VLR to PDY
- Pondicherry to Allahabad—PDY to ALD
- Allahabad to New Delhi or Calcutta (depending on which flight to the US is cheaper)—PDY to NDLS/HWH
This looks like the probable order of cities I'll visit, and the train connections that I'll use—any suggestions, guys?
