The Siemens Mireo is a family of electric multiple units (EMU) designed by Siemens Mobility. It is designed to be a successor to the "Mainline" variant of the company's Desiro EMUs.[2]
The railcars have an articulated design and aluminum carbodies, with 26 meters (85 ft) cab cars on each end of a trainset and 19 meters (62 ft) passenger cars between them, with trainsets between two and seven cars long.[2] The use of aluminum, combined with new control systems, is intended to reduce energy use by up to 25% compared to previous Siemens EMUs.[3] The railcars can reach a top speed of up to 160 km/h (100 mph).[2] Siemens Mobility is currently working on a hydrogen fuel cell prototype.[4]
Siemens introduced the first Mireo railcars at the 2016 InnoTrans trade fair.[2] The first units were ordered in February 2017 by DB Regio, which ordered 24 three-car trainsets with a passenger capacity of 220 for service on its routes in the Rhine valley in southwestern Germany.[3] DB Regio ordered a further 57 three-car high-density sets for S-Bahn service.[4][5] Production of Mireo trainsets began in 2018, with the first completed set unveiled in early December.[5][6] Following testing, Mireo trains are expected to enter revenue service in June 2020.[6]
Mireo Smart
In November 2020, Siemens unveiled the Mireo Smart. This is a standardized product aiming for attractive pricing and faster delivery.[7] It includes features such as more advanced CCTV systems, improved passenger information systems, and full testing before delivery.[8]
Siemens Mobility founded the subsidiary company „Smart Train Lease GmbH“ (STL) in February which allows for near-term leases of Mireo-Smart trainsets.[9][10] The vehicle fleet for the German market will be established during 2024 comprising initially of 12 Mireo Smart, two Plus B and six Plus H. Smart Train Lease expects a common lease to run for one to eight years with a lead time of several months.[11]
Mireo Plus
The Mireo has two variants to run on unelectrified sections. These can be distinguished by their longer high-floor section at the start of the train (four windows instead of three) where the additional devices are placed underneath. They are in passenger service since 2024.
Mireo Plus H
Siemens and Ballard Power Systems are developing a fuel cell system for the trains, which is expected to be operational in 2021.[5]
Mireo Plus B
A battery-equipped variant has been developed.[12] It can run on both electrified lines (taking current from the catenary) and unelectrified lines (using the batteries). It can travel 80 kilometres (50 mi) on unelectrified lines.[4]
In August 2019, NV Baden-Württemberg ordered 20 battery-electric Mireos. They will be used on the electrified Offenburg - Freudenstadt/Hornberg line (Kinzig Valley Railway) and on several unelectrified lines (Rench Valley Railway, Harmersbach Valley Railway and Acher Valley Railway)
These trains use Lithium-titanate batteries (LTO). Toshiba guaranteed 15,000 cycles at 10C by 2019 and 40,000 cycles at 10C by 2022.[13] The LTO batteries are replacing prior usage of supercaps in trains to store the energy from braking.[14]
