Coach composition might have changed that day.
The hill you see in the background is on the entrance side of VSKP station, i.e., trains leaving from VSKP will be going towards the hill, not away from it. So, this train is entering VSKP.
Here is a pic I've found in Wikipedia facing towards the hill. This will give a better idea of the layout. you can see a WAP4 entering the station with some train in this, with the hill in the background.
