Indian Railways — train route altered without intimation

I had booked a reserved ticket in 15659 kanchanjunga express to travel with my family from dakhineswar to noopur for 19 april 2018 about two weeks ago. On the day of the journey at the dakhineswar station i found that the train has changed its route and would pass through neither dakhineswar nor colour.

I was not even informed before about this change. I was unpleasantly surprised and harassed.
