Pakistan has unilaterally decided to suspend the train services on its side.
The Samjhauta Express, commonly called the friendship express, is a bi-weekly train - running on Thursday and Monday.
It runs between Delhi and Attari in India and Lahore in Pakistan.
The train services began in July 22, 1976 under the Shimla Agreement signed between India and Pakistan in 1972.
The word Samjhauta means "agreement" in both Hindi and Urdu.
Thar Express
Pakistan has also suspended the Thar Express train service with India, which links the two countries across the Rajasthan border.
It runs between Jodhpur's Bhagat ki Kothi station to Karachi every Friday night since services resumed on February 18, 2006 after a 41-year suspension.
