Rupsa Junction is the Junction point for Bangriposi (Baripada) line. The track is separated from here. A single diesel track goes towards Baripada from here. If a train is coming from Kharagpur side , then it has to undergo Rake reversal for going to Baripada (eg Simlipal Intercity) whereas the train coming from Balasore side doesn't requires reversal (eg BBS Bangriposi SF).
In the image attached , the most farthest single track going away from main line is this Bangriposi track.
