Starting from delhi travelled to the howrah city via railway route .
Suggestion: If you want to save time or you get irritated by the late timing of the trains then opt either airways or the rajdhani or duronto
Reaching the Howrah railway station and coming out give me the essence of the bengali and truely Indian city that is highly populated ,very economical and have a good sources of transportation
Then I visited a college IIEST Shibpur that was one of the oldest colleges started in 1890's and have a great contribution in giving sharp minds to India beside that one of the laboratory area is included in world heritage site.
Completing this and then went to Ganga Sagar for the bath and kali mata mandir
