ÖBB’s largest commuter and regional train fleet complete: 294 Siemens Desiro ML Cityjets now in service with ÖBB
The largest train
fleet in the history of the ÖBB is now complete. Today at Vienna Central
Station, Siemens handed over the 294th Desiro ML train to ÖBB, marking the
completion of the procurement program. All 294 trains, which operate as
Cityjets, were delivered on time, with some arriving well ahead of schedule.
A total of 273 of the
294 trains were built in Austria through a manufacturing partnership between
ÖBB TS and Siemens Mobility. More than one million production hours went into
manufacturing 898 individual rail carriages to high-quality standards, while supporting
jobs in procurement, logistics and commissioning. This represents a strong contribution
to Austria’s rail industry. The Desiro ML fleet operates throughout Austria in
various configurations, with trains ranging from 75 meters to more than 101
meters in length. The trains have become a popular and reliable part of local
and regional rail services in Austria. The fleet is currently being upgraded
with the latest ETCS train protection system, with completion scheduled for
2028. The trains will continue to play a key role in rail transportation in
Vienna and Austria’s eastern region, including after the modernized Vienna’s central
rail corridor reopens.
Andre Rodenbeck, Executive Vice President Rolling
Stock, Siemens Mobility:
“294 trains delivered on time and years of
reliable service demonstrate that the Desiro ML is a success story. Together
with ÖBB, we have built Austria’s largest local and regional rail fleet, which
today plays a major role in mobility across the country. We are proud of this
achievement and look forward to continuing this success story together.”
An outstanding
industrial achievement
The success story of
the Desiro ML ÖBB Cityjet began with a tender in 2010, which Siemens won. The
train made its world premiere at InnoTrans, the international rail trade fair
in Berlin, in 2016. Passengers, however, had already been able to experience the
new trains when the 2015 timetable took effect, initially on the S7 line
between Vienna Floridsdorf and Vienna Airport. The trains introduced a range of
amenities to local and regional services, including accessibility features, air
conditioning, bicycle storage, Wi-Fi and onboard entertainment.
Europe showcase:
battery-powered pilot project
One notable initiative
was the “Desiro ML Cityjet Eco” project. From the project’s launch in 2019
through the train’s final journey in battery mode in 2020, ÖBB and Siemens
explored the potential for operating the electric multiple unit on
non-electrified routes, including the Kamptal railway line. For the project,
Siemens equipped a test train with an alternative battery-powered drive system.
It was the world’s first battery-powered train fully approved for passenger
service. The train operated on a variety of routes across Austria and achieved
a range of up to 110 kilometers in battery mode. The drive concept used in this
project formed the technological basis for Siemens’s internationally successful
battery-powered trains and is now being used in various projects, including in
Germany and Denmark.
