Deutsche Bahn subsidiary DB Regio is to order two new electric multiple unit (EMU) fleets from Siemens to start running regional services on the Rhine Valley rail line from 2020.

Under the contract, DB Regio will provide regional services for 12.5 years from June 2020, reported International Railway Journal.
