ERTMS on board of CIVIA Renfe trains

Project includes the installation and commissioning of 123 trains to be used in Cercanías Ma-
drid commuter lines. First train is in operation with ERTMS level 1 since Feb 2012

The trains to be equipped
were: 8 CIVIA I (in
commercial operation),
34 CIVIA II (in commercial
operation), 40 CIVIA III (in
commercial operation), and
11 CIVIA III and 30 CIVIA IV
under manufacturing at the
time of the project.

Central car with new rack installed, cabling between cars, cabin
and driver desks were modified:

Today, all units are ready for ERTMS commercial operation.

At the end, Alstom has demonstrated a big experience in the ERTMS onboard equipment, the inte-
gration in several train types, and the management of other national ATPs when required. In total
there are more than 5450 trainsets of 115 different types running with an Alstom ERTMS onboard.
In the first implementations, Adif, Renfe and the Ministerio de Fomento created some functions
(called National Functions) to cover Spanish specificities not included in the ERTMS standard. I
mean, new functions not against the standard, but needed considering operational rules. This
was a must because Spain was (and is) one of the European countries with more km of line and
trains in commercial operation with ERTMS.
A short list of these National Functions is (first version of this specification was created in 2003):

• Función 20: Gestión separada de limitaciones temporales de velocidad según el nivel
• Función 24: Gestión del mensaje por defecto de eurobaliza
