So going by your logic...all passengers boarding from Tata will end up losing a daily train to Allp and instead will have to travel to Rourkela to board the DHN-Allp....This will never happen. Both are run by diff railways ECR & SER. As mentioned by another member already proposals are being sent by SER & ECR. Biggest challenge is setting up TT, availability of rakes and path availability as it passes through so many zones/divisions
