1. TATA-BSB VB would be best suited to be routed via PRR-BKSC/BJE-GMO
2. RNC-BSB VB can be routed either via BKSC-GMO or via LAD-DTO. DTO-GHD route would be the shortest while the GMO route will be faster.
3. It is very likely both will be allotted same slot and similar route, with different days of operation. So, I feel chances for the GMO route is higher, unless there is political pressure from the representatives from DTO etc constituency. Operational feasibility would be better that way.

5. Personally I feel that RNC VB has a higher chance to be considered given RNC is the capital of Jharkhand. Be it via DTO or via GMO patronage will be decent.
