Though the initial idea about the Baku-Tbilisi-Kars (BTK) railway project was raised in the early 1990s, it was not taken seriously due to regional instability and economic difficulties. However, with the realization of the Baku-Tbilisi-Ceyhan oil and the Baku-Tbilisi-Erzurum gas pipelines in 2006, the idea of a railway connection became real once again. The BTK, covering 850 km with a capacity of 5 million tons of cargo (upgradable to 15 million) per year and one million passengers (upgradable to three million), and connecting Azerbaijan, Georgia and Turkey, was launched in 2007 (Klimas and Humbatov, 2016:38; Uysal, 20 October 2014).It was launched without any international backing mainly because Armenia was left out due its occupation of nearly20 percent of Azerbaijani territory after a war in the early 1990s that ended in a cease-fire in May 1994.
