The E331 series (E331系) was an electric multiple unit (EMU) train introduced experimentally from 2007 on commuter services on the Keiyo Line in Japan operated by East Japan Railway Company (JR East). Only one trainset was built, and it differed significantly from other JR commuter EMUs in having articulated cars with shared bogies and using direct-drive motors.[2]
