Why are Inaugural runs of some trains incorrect like for Hazrat Nizamuddin Secunderabad Rajdhani Express which was on 12 February 2002 in reality but it is updated as 21 January 1998.It is incorrect this means that this was the last Rajdhani Express to be introduced in the 20th century but the Swarna Jayanti Rajdhani Express was the last Rajdhani Express in the 20th century.
