The trains are designated for service on the routes Ulm – Augsburg – Munich, Würzburg – Ansbach – Treuchtlingen – Donauwörth – Augsburg as well as Aalen – Nördlingen – Donauwörth. All of the trains are designed to meet projected increasing traffic demand in the region. In particular, the double-decker trains planned for routes to and from Munich will provide a substantial increase in seating capacity.
The Mireo offers 216 and the Desiro HC 538 seats. To further increase flexibility in meeting passenger demand, up to four three-car Mireos can be combined as a train or a maximum of two Mireos combined with a Desiro HC. If even more capacity is needed, two Desiro HC trainsets can be coupled. A multipurpose area is located at each car doorway; 18 bicycles can be transported in a Mireo and 45 in a Desiro HC. All trains are barrier-free for passengers with limited mobility. The trains also have a lift on board in order to provide wheelchair users easy access at stations with low platforms.
A real-time passenger information system shows arrival and departure times as well as connections at the respective stations. The trains are equipped with high-frequency window glass specially developed by Siemens Mobility to substantially improve mobile reception. In addition, the trains will be prepared for a possible later installation of WLAN technology.
