For the multi-system variant of the Vectron, we can test all electrically operated variants (AC 15 /25 kV and DC 1.5/3 kV) in our locomotive testing centre. What particularly distinguishes us with the class 193 Vectron is that we carry out the introduction of the first overhaul cycles in cooperation with the manufacturer and our customer in order to drive forward the improvement and further development of maintenance and its documentation (maintenance programme). Thus, generate the greatest possible customer benefit. 

The class 187 is the first variant of the Traxx-3 series to be equipped for 15 kV 16.7 Hz and 25 kV 50 Hz AC locomotives. We can test these in our locomotive testing centre. Prior to the introduction of the first overhaul cycle, there is close cooperation with the manufacturer, ECM 2 DB Cargo and a renowned adhesive manufacturer to develop the maintenance of new composite materials. This means that in future we will also be able to offer this service independently from a single source. 

The class 1462 with the product name Desiro HC has been in operation at DB Regio in the Rhine Valley network since June 2020 with 15 four-part multiple units. Further multiple units (43 four-part and 8 six-part) have been ordered by DB Regio for use in two other networks for the 2023 timetable change (Franconia-South Thuringia network) and 2024 (Danube-Isar network) respectively. With a vehicle length of about 105 m for the four-part multiple unit and about 157.5 m for the six-part versions, the lengths of the multiple units deviate from the established series. This is due to the body lengths of about 26 m for the end carriages and about 25 m for the middle carriages. Another special feature compared to other multiple units is that the end carriages are single-deck and the middle carriages have a double decker coach concept. The running gear configuration consists of two motor bogies per end carriage and two running bogies per middle carriage. 

The newly developed class 463 series with the product name Mireo has been in service since June 2020 in various networks, including the Rhine Valley and Rhine-Neckar networks. The 3-part multiple unit train with a length of about 70m used in these networks is expected to expand the DB Fahrzeuginstandhaltung portfolio from 2024. The challenges with this classes are in the extended carriage bodies. The end carriages are 26m long, the middle carriages 19m. In the previous series, e.g. EMU 430, a similar multiple unit length was realised with four carriage bodies. The bogie configuration has, in addition to two final drive bogies at the respective wagon transitions, “Jacobs running bogies” with internally mounted running wheel sets, a technology that has so far only been used in the ICE 4. The Mireo will also be used with alternative drives in the future. Deutsche Bahn will test a hydrogen-powered multiple unit (Mireo plus H) in 2024. External RUs will operate battery-electric multiple units of the type Mireo plus B on several networks from 2023.
