With his electric trains JR evokes the spirit of childlike wonderment and play. Mechanical train cars move back and forth on their rails, staging an optical illusion every lap they run. Fleeting faces are unveiled to the visitors as they move in closer to the installation, faces appear as 28 electric train wagons overlap. The image revealed disappears as quickly as it appeared, letting each train go at his own pace.
JR’s use of trains is a direct reference to his Women Are Heroes project in the Kibera slums in Nairobi,
Kenya. JR pasted the eyes of his subjects on a train, as well as the bottom half of the their faces on the slopes of the slums leading up to the train tracks. For a split second when the train passed by, their eyes reunited with their smiles and their faces were once again complete.
