Answer: Thar Link Express

Thar Link Express is the Indian segment of the international passenger train. Thar Express runs weekly by Indian Railway utilizing its own coaches covering Jodhpur and Munabao stations. Passengers from Munabao then clear their customs and are shipped to over the outskirt to Zero Point station where the Thar Express takes all passengers to Karachi, Pakistan.

As of August 9, 2019, the Thar Express has been dropped until further notice due to escalating tensions among India and Pakistan.  

The track between Barmer, framing some portion of the then Jodhpur princely State, and Shadi Palli in Sindh province, on which the current Thar Link Express runs, was opened in December 1900 to run the Sind Mail, which ran between Bombay and Karachi through Munabao. In the journey going via Ahmedabad - Palanpur - Marwar - Pali - Jodhpur - Lun - Barmer - Munabao - Khokhrapar - Mirpur Khas - Hyderabad. During the Indo-Pakistani War of 1965, the rail track was besieged and annihilated by the Pakistan fighters planes, and the Mumbai-Karachi train ended forever.  

BACKGROUND

On 28 June 1976, India and Pakistan consented to the rail communication arrangement, to standardize the relations between two countries in the wake of consenting to the Simla Arrangement of (2 July 1972) hardly any months after the finish of Indo-Pakistani War of 1971, when the reciprocal relations had soured after the Indian Army had to prevail with regards to freeing Bangladesh.

The sustainable rail communication arrangement was again reached out by the two countries from 19 January 2016 to 18 January 2019.
