Bombardier Transportation received an order for 90 electric multiple units of the 430 series from DB Regio AG. The order value totals $648 million. To date 87 trains of the same series 430 have already been ordered for the Stuttgart region and production of these is under way.

DB Regio won a European-wide tender from the Rhein-Main-Verkersverbund (RMV) in November 2011, securing the transportation contract for the Rhein-Main rapid transit network. The new 90 four-car electric multiple units of the 430 series are to be used in the suburban-network Kleyer, covering more than 4.5 million train miles a year, from December 2014 onward. The trains are able to accelerate rapidly and can reach speeds of up to 87 mph during operation.

The electric multiple units of the 430 series have 24 electric swivel-sliding doors, enabling easier and more rapid passenger flow. The trains will also provide a spacious multi-purpose area to ensure greater convenience for passengers traveling with bicycles. Energy-saving indirect LED lighting integrated in the luggage racks enhances the interior ambience. All coaches are joined together by convenient walkways. Information on connecting trains is displayed in real time via a modern passenger information system with a monitor in each of the entrance areas.

Video monitoring cameras, combined with an open layout, which allows a clear view of the train interior over its entire length, help increase safety and security for all passengers. The vehicles will be built in Germany by Bombardier and by Alstom prior to final delivery in 2014.
