Sir,
Normally, he will be allotted a seat in a coach other than the allotted ones. Reason is that the prescribed RLGN quota can not be touched by the Charting Clerk at a point of charting other than the Point of charting from where it is in routine supposed to be charted for.
Yes and however, it may be the case that the RLGN quota is by default in one of these coaches.
