A rail system in Uilo has been the subject of debate since the 1990s, when the city was gaining immense economic growth. The project was finally approved by the City of Uilo in 2009, following the completion of Kelvia light rail. Future plans for the system include two more lines that will expand the system into the inner suburbs and outskirts of the city.

History
A rapid transit system in Uilo was first conceived as early as the 1990s, when the Uilo city government began studying the feasibility of such a system. However, little progress was made until construction of the Kelvia light rail began in 2001, when plans for the metro began to be drawn up. In early 2006, public transport officials sent a proposal for two heavy rail lines to be built, both of them radiating from the downtown area. This was later downgraded to a medium-capacity rail system similar to the and the first two stages were finally approved by the city government in 2009, followed by the second line in 2014.

In March 2010, the Uilo Metro Corporation was formed to oversee the construction and future expansions of the system. Construction of stages 1 and 2 began in April 2013, with completion then estimated for 2020 and stage 3 to be opened in 2023. The first two stages would form the core section of Line M2, also known as the City Line.
