The agreement between Pakistan and India on rail communication has been extended with mutual consent through diplomatic channels for a period of three years.
According to an official statement issued on Friday, the agreement has been extended from January 19, 2016 to January 18, 2019.
The agreement, signed on June 28, 1976, enables India-Pakistan rail communication both in respect of goods and passenger traffic.
Currently, passenger and goods traffic operates on Delhi-Lahore route via Attari Wagah, and passenger traffic between Jodhpur and Karachi via Munabao Khokhrapar.
A brief meeting between Sharif and his Indian counterpart Narendra Modi on the sidelines of the UN climate change summit in Paris on November 30 last year followed by talks between the two countries national security advisers in Bangkok, appeared to have broken the ice.
