Mireo Plus H and Mireo Plus B: Technological advances
for Brandenburg’s regional rail
Both the Mireo Plus H and the Plus B are state-of-the-art
trainsets operating with hydrogen or battery hybrid drives. They feature a 1.7-MW
powered traction system capable of acceleration of up to 1.1 m/s2
and have a maximum speed of 140 km/h. The Mireo Plus H and Plus B trainsets are
designed to be energy-efficient and environmentally friendly: Their monocoque,
welded lightweight aluminum structure, improved aerodynamics, energy-efficient
components, and intelligent electrical system management effectively reduce the
use of resources as well as emissions.
“A new era is beginning in Berlin and Brandenburg for
the East Brandenburg and Heidekrautbahn rail networks. We will be seeing the
shift from conventional diesel-powered trains to extremely ecofriendly trains.
The Heidekrautbahn will even be launching CO2 emission-free operations on
non-electrified routes in the Berlin and Brandenburg regional rail transport
system. The new train design fits this spirit perfectly,” said Thomas Dill,
Division Head, Center for Urban Transport and Quality Management, VBB.
NEB ordered a total of 38 Mireo trainsets with
alternative and environmentally friendly drives from Siemens Mobility in 2021
and 2022. Beginning in December 2024, 31 battery-powered Mireo Plus B trains will
serve in the East Brandenburg network, and seven hydrogen-powered Mireo Plus H trainsets
will operate on the Heidekrautbahn. This will mark the first time that
hydrogen-powered trains are used in Brandenburg and Berlin. The switch from
diesel to hydrogen and batteries will reduce CO2 emissions by around
14.5 million kilograms a year and save around 5.5 million liters of diesel.
The use of hydrogen-powered trains on the
Heidekrautbahn is part of the
Heidekrautbahn hydrogen rail system
system, a joint
scientific pilot project funded by the federal government and the states of
Berlin and Brandenburg. The project is setting up a regional, sustainable
hydrogen infrastructure that also includes a hybrid power plant and a tank
system. All train operations on the RB27 are to be powered exclusively with
renewable, regionally generated green energy.
The project “Use of hydrogen fuel cell drives in local
transport in the district of Barnim” is being funded by the federal government
as part of the national innovation program for hydrogen and fuel cell
technology. The program’s funding is being coordinated by NOW GmbH and
implemented by project lead Jülich.
