TMP 205 rev.00 ERTMS is a major European industrial project
(similar to Galileo for satellite navigation or SESAR in air
traffic management) and provides increased export opportunities for
the EU. Safe train positioning Satellite navigation is set to
revolutionise the rail sector, and ETCS will make it possible to
monitor the exact location of each train in real time

TMP 205 rev.00 Technology shift Move the intelligence from the
track side to the trains Use GNSS to replace the fixed blocks and
reduce trackside equipments Improve the safety especially on low
traffic lines Increase the frequency of train without investing on
the infrastructure EGNSS (EGNOS, GPS Galileo) A public
EGNOS-GALILEO infrastructure is key to provide positioning function
to the ERTMS

CERTeT 18 C OSTS AND BENEFITS (NPV IN 35 YEARS ) BY TYPE OF
LINE (E URO ) Economical Evaluation on Regional Network in Europe
Overall, the introduction of ERTMS satellite in the Regional
European Network * generates benefits for some 35 billion Euro,
with costs which sum up to 16 billion Euro in a 35-year time
horizon. The overall Benefit/Cost Ratio is 2.2. * selected
countries NB: This figures derive from a parametric expansion,
therefore cannot be as accurate as a case-by-case analysis which
takes into account specific national features in terms of control
systems and project timetable
