Indian Railways — unnecessary train late of train no. 63511 at regular basis

The train, burdwan to purulia memu passenger train (63511) is reaching asansol daily by 45 min. To 1 hour late. Becoming a daily-passenger, we are facing the problem daily. The train is starting sharp at 8:40 am from burdwan but it is reaching asansol between 11:30 am to 12:00 pm, whereas it's right time to reach asansol at 10:35 am. So, our request is either change the time of train in your time-table or stop the train to run because it can't reach in time.
