Metro Riel is a light rail line proposed for Guatemala's capital, Guatemala City.

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.
