Rainforest Ecological Train, Tourist train in Iguazu National Park, Argentina

The Rainforest Ecological Train is a railway service that moves visitors through 3.7 kilometers of rainforest within Iguazu National Park. The system links three stations together and carries up to 250 passengers per trip.

The system began in 1999 when British manufacturer Alan Keef Ltd built the first locomotives and wagons, and operations started in 2001. This marked Argentina's first gas-powered train service of this kind.

The open-sided wagons let you watch rainforest animals and plants as you travel through the park. Birds, butterflies, and other forest creatures often appear when the train moves through the thick canopy.

The train is included in the park entrance fee and saves time reaching different viewing points. The open design means visitors need protection from rain or intense sun.

The first battery locomotive entered service in 2017, and a second followed in August 2018. The trains run on 600 mm Decauville track, and the line stops when animals cross. The carriages were later supplied by Metalúrgica Liderar of Rosario and Glastra S.A.C.I.
