Explanation:

• Indian Railways will run its first Buddhist Circuit train from 20 to 26 October 2019 covering sites related to Gautam Buddha in India and Nepal.
• It covers destinations such as- Lumbini (where Buddha was born) Bodhgaya (where Buddha gained enlightenment) Sarnath (where Buddha gave his first sermon) Kushinagar (where Buddha attained nirvana)
• The significance of these destinations can be seen in Mahaparinirvana sutra, wherein the Lord Buddha tells his followers that they can attain merit and a noble rebirth by going on pilgrimage to these places.
