Prime Minister Atal Bihari Vajpayee will travel by a special train from Katra to Ayodhya on February 7 to dedicate to the nation a mega-bridge on Sarayu River.
The distance between the two stations is eight kilometres, a railway spokesman said in New Delhi.
This will be the first train journey by a prime minister after Indira Gandhi travelled from Chandigarh to New Delhi in the 1980s.
Former prime minister Morarji Desai had also travelled by a train in 1978.
