Two broad gauge Pakistan Railways lines terminate near the border at Chaman in Balochistan near the Khojak Pass; and at Torkham, the border town near the Khyber Pass. Various proposals exist to extend these lines on to Kandahar and Kabul respectively. In 2010, Pakistan and Afghanistan signed a Memorandum of understanding for going ahead with the laying of rail tracks between the two countries. Work on the proposed project was set to start in late 2010.
