Deutsche Bahn's mass transit arm DB Regio has ordered 39 trainsets from Siemens to operate on the Rhine Valley rail network in south-west Germany.
DB Regio plans to operate the network with these new trains beginning in 2020.
The order comprises 15 Desiro HC and 24 Mireo trains. It marks the first order for the company's new articulated Mireo regional train platform.
Siemens high-speed trains, regional trains and locomotives business CEO Sabrina Soussan said: "Following the product launch, we very quickly succeeded in entering the market with our new Mireo train platform.
"The Mireo combines economy with sustainability and offers optimal flexibility over its entire lifecycle."
Train service in the Rhine Valley is planned to be restructured and upon completion, a separation will be made between fast cross-regional trains running between the major cities, and a regional suburban rail system (S-Bahn) with stops at all local stations.
The number of trains operating in the region will be expanded simultaneously.
Between Freiburg and Endingen/Breisach, the Mireo will operate as a regional train (RB) along the Offenburg-Freiburg-Basel/Neuenburg (Switzerland) route, as well as in the Kaiserstuhl area on Sundays.
Noise is substantially reduced due to its new design and quiet bogies.
The lightweight, three-car train has 220 seats and is energy-efficient. Its intelligent board network management system reduces energy consumption by 25%.
Operating as a regional express on the Karlsruhe-Offenburg-Freiburg-Basel route, each Desiro HC train will comprise four cars, with each end car having a single-deck design and the middle two cars being double-deckers.
More than 50% of the interior space is barrier-free and equipped to meet the needs of mobility-impaired passengers.
The 105m-long trains offer 410 seats and spacious legroom. Both regional train types have been designed to have speeds of 160km/h.
