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 Satellite-based solutions for Train Control Systems Exploit new technologies Ensure ERTMS compatibility Increase market EGNSS EGNOS operative GALILEO under development ERTMS Lower operational costs Improve competitivity Making investments more attractive Space technology Rail applications The virtuous cycle Virtual balise

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 17 R EFERENCE SCOPE Segmentation of Regional Network in Europe  Unit costs and benefits per km are applied to the clusters of lines according to their types.

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
