If you are a fan of Shahrukh Khan, do take a ride on this as this was the train on which he danced to the tunes of Chaiyya Chaiyya (the song from the movie Dil Se) <3
The total journey one way is 1 hour. There are 4 stations in between. The journey is beautiful through the forests and valleys. To make it more filmy, play the song Chaiyya Chaiyya while travelling ;)
