Hitachi Ltd. said Wednesday it has been awarded a contract worth up to $2.2 billion to procure as many as 800 rail cars for Washington's metro service in the United States.

The first cars are to be delivered to the Washington Metropolitan Area Transit Authority in 2024, with local group company Hitachi Rail Washington to build a new factory in the U.S. capital to oversee their design and manufacture.

The new rolling stock will be equipped with the latest digital screens and electrical outlets, and also feature an environmentally-conscious design with an improved ventilation system.

The WMATA, which operates six metro lines in the Washington metropolitan area serving 91 stations, is one of the key public transport systems in the United States. There are currently 1,292 rail cars operating on its metro network.
