The MIA e Train consists of two three-car cable-driven MiniMetro trains developed by Leitner-Poma (unlike the Skytrain and MIA Mover which use Mitsubishi Crystal Mover vehicles).

The two trains run on parallel independent guideways and shuttle back and forth between the two stations.

[1] The MIA e Train opened in 2016 and replaced an earlier system that was built in 1980.

It operated in a similar fashion to the current system and used six Westinghouse C-100 vehicles in two three-car trains, which were also the same vehicles that originally operated on Downtown Miami's Metromover, which opened in 1986.

On November 28, 2008, the train on the south guideway failed to stop at the main station and crashed into the wall at the end of the line, injuring seven people.
