I am living in Ghaziabad. Fastest train from Ghaziabad to Kolkata is Kalka Mail which takes 24 hours 55 minutes. If Rajdhani Express would have been operated by private organisations then they must have increased fare for revenue and given stoppage at Ghaziabad for attracting passengers. Stoppage of Rajdhani at Ghaziabad may save 8 hours. If i meed to board to Rajdhani, i need to spend around 3 hours more as of now so many passengers take Kanpur Shatabdi till Kanpur and then they take Rajdhani gang.
