In 1927, work began on the construction of the hydroelectric power plant in Naharayim.

The Electric Company, under the direction of Pinchas Rotenberg, founder and first director of the Company, supplied the workers with the most up-to-date equipment of those times; bulldozers, drilling machines, tractors and even an on-site train system that transported goods on narrow train tracks.

Rotenberg bought train wagons and engines to assist in clearing soil and rocks that had been dug out, and for transporting the many building materials necessary for the building of the plant.

Painted on the train wagons were large Hebrew letters, abbreviations of the Israel Electric Company.

In 1992, the train engine and wagons were found rusty and destroyed in a nearby field of thorns near the Naharayim power plant. After intensive efforts and cooperation with others involved, the train engine was returned to its home.

The first people to work on the engine were staff from the Council for Conservation from Kibbutz Ein Shemer. Much work was needed to clean up the rust, fix the engine and find the many parts that were missing. Difficult as it was, the team was successful and the engine was reconstructed and repaired.
