The Lahore Metro was first proposed in 1991 and reviewed in 1993 by the
Lahore Traffic & Transport Studies, funded by the
World Bank. The project was subsequently shelved. In 2005, the
Ministry of Transport revisited the project and carried out a feasibility study. In 2007, the
Asian Development Bank provided to conduct a study on the project. The initial plan called for an 82-kilometre (51 mi) rail network with 60 stations to be constructed in four separate phases. The first phase involved the construction of a 27-kilometre (17 mi) rail line between
Gajju Matta and
Shahdara Bagh, with an 11.6-kilometre (7.2 mi) section underground. Construction was expected to start in 2008 and be completed by 2010. However, in 2008, the project was shelved again as priorities shifted to other projects. In June 2010, Malaysia-based
Scomi International proposed a US$1.15 billion
monorail alternative, but that was not approved. At a ceremony in May 2014, an agreement was signed by Chief Minister Punjab
Shahbaz Sharif, alongside
President Mamnoon Hussain and
Chinese Communist Party general secretary Xi Jinping, which gave the go-ahead for the construction of the Orange Line. The project was estimated to cost $1.6 billion. ==Lines==
