Siemens Mireo is a regional and suburban commuter train developed by Siemens for premium-class mass transit.
It is an energy-efficient and flexible option ensuring sustainability and safety at reduced operating costs. Its lightweight design enables increased freedom of movement.
The maximum speed of Mireo can range between 140km/h and 200km/h. The train has shorter construction time and is suitable for mass-transit and regional services.
The Siemens Mireo platform was presented at the Innotrans rail trade fair in 2017. It is projected as a solution to meet the growing demand for public regional and urban mass transit. The Mireo range includes the Mireo Plus B and Mireo Plus H models.
Siemens Mireo design details
The Siemens Mireo electric multiple unit (EMU) is a scalable articulated train featuring new aerodynamic design and quiet bogies with inside bearings, which substantially reduce the noise level.
Improved aerodynamics also contribute to lower weight than previous models. The design enables a long service life, reduced maintenance costs, and improved availability of the train.
All the components of the train are installed on the roof or beneath the floor, allowing for maximum capacity through the creation of more seats.
The platform is available in different car body lengths with train lengths ranging between 50m and 140m, and train configurations of two to seven-part trainsets.
The vehicle incorporates Sibas PN to provide a smooth engineering workflow and intelligent cabling along with predefined proved solutions and modules, enabling quick delivery to the operators.
The train’s software undergoes detailed tests prior to commissioning and the safety-related data is recorded for maintenance, diagnostics and vehicle control, ensuring safe operations.
The EMU provides a seamless connection via on-board services such as internet, passenger assistance system, train portal, passenger information system, driver advisory system, conductor assistance system, CCTV safety monitoring, real-time passenger counting, and real-time analysis of diagnostic data.
Interiors of Siemens Mireo
Mireo’s three-car trains feature 220 seats and can attain a maximum speed of 160km/h. The interiors include large displays to provide passengers with information, on-board internet access and surveillance systems.
The train offers spacious seating with CO2-based air-conditioning and multi-purpose areas. It can accommodate up to 27 bicycles and provide barrier-free access to the restrooms for passengers with reduced mobility.
The car doors have a sliding platform to reduce the gap between the platform and train. The seating design helps reduce the costs associated with the cleaning of the passenger area.
The height of the train’s entrance ranges between 600mm and 800mm and can be modified according to the customer requirements.
Siemens Mireo sustainability features
Mireo has a lightweight integral aluminium monocoque construction with intelligent board network management system and energy-efficient components, which lead to a 25% reduction in energy consumption. The driver assistant system installed in the vehicle delivers 30% more energy savings.The trailing bogies with inside bearings help save energy while the architecture allows for fewer bogies and car bodies.
The train’s transformer features a high level of efficiency and utilisation of the electrodynamic (ED) brake to the fullest ensures the vehicle consumes less traction energy. Siemens incorporates materials that will enable the recycling of 95% of the train, upon completion of the lifespan.
Orders and deliveries
DB Regio was first customer for the Mireo platform. The company placed the first order for 24 Mireos for the Rheintal network in March 2017. The trains will be deployed from 2020.
Landesanstalt Schienenfahrzeuge Baden-Württemberg (SFBW) signed a contract to procure 20 Mireo Plus B trains in March 2020. The trains will run on Network 8 of the Ortenau regional system and are expected to be delivered by December 2023.
The order also includes a provision for maintenance services for 30 years.
An order for 57 regional trains was placed by DB Regio in August 2017. In January 2019, Go-Ahead ordered 44 three-car trains for operating across Augsburg. DB Regio signed another contract for 18 more units in February 2020.
