I am going to be staying in Delhi for a few days, and during my stay day, I am very busy, apart from the last day there. On my last day, I am hoping I can go to see the Taj Mahal and be back in Delhi the same day. I would travel by train so need some suggestions if I plan the same day Taj Mahal tour by train? Some help which I require is what train I should take? How I should plan my day for the trip?
