CR/KR TC boards from MAO. Now i am not sure confirm where he alights - at PNVL or BSR. This thing i don't know. If he alights at PNVL , then there no problem. But if he alights at BSR itself , then there are chance he may go for PNVL boarding tickets.
And this train takes 2 hrs due to Slack given for Zonal transfer. It is made to arrive BSR (WR) on time , so that they could maintain its punctuality.
