# The Grand Paris Express line 15 South moves for the first time

The countdown is drawing to a close: after the first manual run in November 2023
at the Champigny maintenance centre, preparations for the entry into service of
line 15 South have reached a new phase with the start of dynamic tests in
automatic mode. This covers the entire transport system, from the MR6V trains to
the station equipment.

The first runs took place in the same geographical area as at the end of 2023,
i.e. part of the track connecting to line 15 South, but with a major change:
this time, no one is physically at the controls in the train. The commands are
sent from the Operation Control Centre (OCC). Staff remain on board the train to
ensure that the automatic train control system is operating correctly, and that
safety is being maintained.

> This is the culmination of 10 months’ work by the Rolling Stock and Automatic
> Control System project management teams (MOE MR-AC), which began in early
> 2024. Day after day, we are working with them to set up these test runs, and
> we are preparing and monitoring the first dynamic tests, after carrying out
> all the upstream checks. The start of these driverless tests rewards the work
> of around thirty employees. Now, more than ever, we’re on target!

### SYSTRA France mobilised for a crucial new phase

A wide range of systems expertise was mobilised to carry out our assignment.
SYSTRA was involved as project manager in the preparation and monitoring of the
tests: in this capacity, we covered all the static tests on the rolling stock,
where the correct operation of all the on-board and on-track systems was
checked, as well as the interface between the train and the automatic driving
systems, the detection of beacons and all the safety equipment in the tunnel.

The campaign of dynamic tests in automatic mode, for the trains and station
equipment, will last until commissioning, under the supervision of Siemens. As
far as SYSTRA is concerned, no personnel are on board, but we are making sure
that the tests are carried out correctly, by setting up a watertight red zone
around the test perimeter. No access to personnel is possible when the tests are
taking place, and total detection of the entry of any person into the
electrified track area is installed.

> The start of the dynamic tests marks a new decisive stage in the overall
> progress of line 15 South. The efforts of all the project management and
> Global System Integration (ISG) teams who have supported Alstom,
> Siemens/Hitachi and Société des Grands Projets in preparing for these tests
> are to be commended. Everything about this project is new, from the rolling
> stock to the operating system, from the infrastructure to the objectives
> assigned to the project, and everyone was right on target: congratulations!
> Jérémie Wajs, Head of ISG, SYSTRA France

The next stage will be the first crossing of a Grand Paris Express station,
scheduled for the autumn, before tests are extended in 2025 to the entire line
and station equipment, which will also be tested and integrated into the overall
system being checked by our teams.

_SYSTRA team supervising the test run_

With fifteen months to go before it enters service, line 15 South is becoming
more and more of a reality. In April 2024, the last rail on the line was welded,
and the 37km of tunnel are now equipped with track. The final civil engineering
operations were completed this summer at Saint-Maur-Créteil station, and all the
passenger buildings for the 16 stations are now emerging in the area. Meanwhile,
Villejuif – Gustave Roussy station, equipped with a dedicated local OCC, is
preparing to open to line 14 users in December 2024, ahead of schedule.

The equipment currently being installed, under the supervision of the project
management teams, includes air conditioning and ventilation systems, electrical
networks, the installation of lifts, escalators and platform façades, and the
laying of the final coverings. At the same time, the equipment needed to control
the metro is being installed: the technical premises are gradually being fitted
with the servers and other transformers that will power the stations and tunnel
and automate the line.

SYSTRA France’s teams are also working on other sections of the Grand Paris
Express, such as lines 16 and 17, where the first trainset was delivered on 3
October 2024 at the Aulnay-sous-Bois maintenance centre. SYSTRA is responsible
for project management assistance for the operation and maintenance of all the
lines of the Grand Paris Express, and in particular for the preparation of
maintenance infrastructures for the super metro in the greater Paris region.
