Indian Railway — Train status update blunder

Address:

Patna, Bihar

I was travelling on train no 12351 - Danapur express. Its final destination is Rajendra Nagar. Train was stopped at a Gulzarbagh station which is not in its list and train status was marked as arrived at destination. Train was stopped for more than 2 hour. Later I came to know that this practice is happening regularly. My friend was also travelling on the same train and he also reported this anomaly.
