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]
