Considering the need of the country’s metropolitan cities for subway cars, MAPNA Locomotive Engineering and Manufacturing Company (MLC) has put the design and localization of subway trains on its agenda. The project aims to maximize the capabilities of local specialists and manufacturers while also developing a viable supply chain. MLC has enjoyed consultancy of reputable international companies in this project. The implementation of this project has both reduced reliance on imports of this strategic product and helped fully utilize all of the potential capacities of local manufacturers.
