Herat Province of Afghanistan. Afghanistan-Turkmenistan rail connections A 10-kilometer-long broad gauge line extends from Serhetabat in Turkmenistan to the town of Torghundi in Afghanistan, which is about 115 km to the north of Herat. An upgrade of this Soviet-built line, to renovate and connect the line from Torghundi to Herat, began in 2017. A second rail connection between the two countries is that which extends from Aqina dry port in Faryab Province of Afghanistan, via Imamnazar to Atamyrat (a.k.a. Kerki), where it connects with the Turkmen rail network. The line extends from Aqina south to Andkhoy in Afghanistan, which is approximately long. It will be extended from Andkhoy in the future to other parts of Afghanistan. Afghanistan-Uzbekistan rail connections There is a 75-kilometer-long rail line between Uzbekistan and the northern Afghan city of Mazar-i-Sharif, all of which is built to broad gauge. The line begins from Termez and crosses the Amu Darya river on the Soviet-built Afghanistan–Uzbekistan Friendship Bridge, finally reaching a site next to the Mazar-i-Sharif Airport. A survey is being conducted in extending the line to Kabul and then to Peshawar. Other borders There are no rail links to Pakistan, China or Tajikistan.
