why the vehicle must be taken out of service
immediately. In order to meet Alstom’s
high demands, the wheelset sensor, which
has proven itself over many years, was completely
modified once again. The result was
a new stainless steel temperature probe
based on PT1000, which, in two different
versions, fully complies with the current
“railroad standards” with regard to fire protection,
vibrations, etc.
JUMO’s many years of experience in the
demanding railroad industry made it possible
to meet Alstom’s high expectations. The
current order includes the delivery of several
thousand temperature sensors for the first 50
trains. Production started at the end of 2020
and the deliveries will be staggered until 2025.
The TGV 2020 project is a
prestige project
The TGV 2020 project is a prestige project for
the French government. Everyone involved is
working flat out because the Summer Olympics
will be held in Paris this year - and the
whole world will be watching the French metropolis.
50 trains are to be put into service by
March 2027, with a further 50 trains by October
2031. In the second tender, there is a possibility
that JUMO will once again participate in
the project with its proven technology.
The TGV “belongs to France” like French wine,
hundreds of different types of cheese or the
Tour de France. Around 42 years ago, a Train
à Grande Vitesse (TGV) left Paris for Lyon for
the first time. In September 1981, it was not
yet possible to travel from Paris to Lyon, 400
kilometers to the south-east, in two hours because
the new high-speed line was not yet fully
completed.
Today, the TGV speeds through the country
at 320 km/h and connects Paris with Lyon
in two hours. The TGV only needs three hours
and eleven minutes to cover the 765 kilometers
between the capital and the port city of
Marseille.
Since July 2023, there has been a direct
connection between Frankfurt/Main and the
terminus station not far from the French Atlantic
coast, Bordeaux, which is around 1,300
kilometers away. The TGV covers the distance
directly in around seven hours and 40 minutes.
Previously, rail travelers had to change
trains in Paris and also had to use the station
in the French capital.
