Metro Riel

In October 2016, it was reported that Spanish consulting engineer IDOM conducted a feasibility study into a 20-kilometre (12 mi) light rail system for Guatemala City, evaluating the cost at $770 million.^{[clarification needed][2]} Journeys between the two termini of the line would take around 40 minutes at a commercial speed of 30 km/h (19 mph) on a largely segregated alignment.^[3] The project was then shelved, but revisited in 2018.^[4]

In April 2019, the Guatemalan national competition agency Pronacom and public private partnership promotion agency Anadie began seeking a consultant for an advanced design study for Metro Riel.^[5]

In 2019, the municipality of Guatemala City signed an agreement with the country's railway infrastructure manager Ferrovías to use an abandoned heavy rail alignment for the project.^[6]

Preliminary construction works began in 2024, with a targeted opening of the first phase in mid-2027.^[7]

The Metro uses part of the allignment of the former heavy rail line.
