HL Project Photo Gallery

This project is started in 1999 in order to convert and rebuilt an old locomotive into plug in hybrid electric shunting locomotive. The project was conduct by help of the Irankhodro company R&D center and the university of Yazd. The locomotive is built in 12 months and it was the first world plug in hybrid shunting locomotive. All the main components were built by our team. The locomotive is tested and approved by Iranian railway system.
