The Shatabdi Express is one of the best trains running between Lucknow to Delhi, Shatabdi Express is actually an important train that runs between two important cities all over in India. This Wikipedia page gives more details about the Swarna Shatabdi Trains
It is one of the best and fastest way to reach from Delhi to Lucknow or from Lucknow to Delhi. I have been travelling in the Shatabdi Express from last 20 years as far as I remember.
Though the methods of booking a ticket on the train have changed in the last 20 years, the experience still remains amazing. The Train departs from New Delhi at 6:10 a.m. and reaches Lucknow at 12:40 p.m.
And when it departs from Lucknow at 3:35 p.m. it reaches New Delhi at 10:15 P.M so it takes around 6 hours and 30 minutes to cover the distance of 513 km.
So when I was going to New Delhi from Lucknow I decided to make a video showing you my experience of the journey from Lucknow to Delhi in Swarna Shatabdi Express.
