Siemens Mireo is a family of electric multiple units (EMU) designed by Siemens Mobility. It is designed to be a successor to the "ML-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]
Variants

This is the standard and baseline version of the Mireo family, designed for electrified tracks, it is highly modular and optional to fit for customer needs.
Mireo Smart
In November 2020, Siemens unveiled the Mireo Smart. This is a standardized Mireo baseline product which only comes in the 3-car configuration and a fixed cabin layout, 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 ÖBB
| Mireo ÖBB | |
|---|---|
| Stock type | Electric multiple unit |
| Constructed | 2026-present |
| Fleet numbers | 4864 001-031 (Railjet version) |
| Specifications | |
| Train length | 73–106 m (239 ft 6 in – 347 ft 9 in) |
| Maximum speed | 160 kilometres per hour (99 mph) |
| UIC classification | Bo’Bo’+2’2’+Bo’Bo’ Bo’Bo’+2’2’+2’2’+Bo’Bo’ |
| Safety systems | ETCS, LZB, PZB, Sifa |
The Mireo specially configured for the Austrian Federal Railways (ÖBB) are equipped with classic bogies which is similar to its predecessor Desiro ML, instead of Jakob bogies seen on the standard Mireo lineup. Therefore it will also open up more space in the under-carriage section for additional equipment.[12]
A total of 100 sets were ordered by the Austrian carrier including 31 4-car trainsets (Class 4864) dedicated to long-distance services (Railjet), 33 4-car and 36 3-car trainsets for regional services (Cityjet).[12]
Mireo Plus
| Mireo Plus | |
|---|---|
Siemens Mireo Plus H at Innotrans 2022 | |
| Stock type | Electric multiple unit |
| Fleet numbers | 0563 |
| Specifications | |
| Train length | 46.56 metres (152.8 ft) |
| Maximum speed | 140 kilometres per hour (87 mph) |
| Safety systems | PZB, Sifa |
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.[13] 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). This was later entended to 28 units.[14]
These trains use Lithium-titanate batteries (LTO). Toshiba guaranteed 15,000 cycles at 10C by 2019 and 40,000 cycles at 10C by 2022.[15] The LTO batteries are replacing prior usage of supercaps in trains to store the energy from braking.[16]
In 2025, Midtjyske Jernbaner started operating the Plus B.[17]
Mireo City

The Mireo City is a sub class family focused on suburban rail transport.
The Munich S-Bahn ordered 90 13-car variant of the Mireo City and has an option for 90 sets more.[18]
The head form of the Mireo City for Munich S-Bahn is aerodynamically optimized by a design team at Siemens Mobility lead by Benno Schiefer for both directions in order to reduce drag and save energy costs.[19]
