6 Measurement systems on IRIS 320 Track Measurement Systems Loaded track geometry with inertial laser measure, replaces Mauzin inspection. Vehicle / track interaction replaces Melusine inspection. Axle boxes accelerations research program with short defects analysis. Rail surface defects Video pictures with RT analysis from a linear camera. Wheel rotation noise short-pitch corrugation and specific defects. Catenary Measurement Systems Catenary dynamics Detection of electric arcs Stagger and height image processing Additional Functionalities included later Wear of contact wire Static geometry of the contact wire Power frequency shape analysis. stagger height 6

7 Signalling Measurement Systems To guarantee the safety of the train itself, measuring equipments of signalling control are distinct from the similar equipments in charge. KVB (speed monitoring by beacon), Icc (short-circuit current), BSP (phase-lock loop), Zt (transverse impedance), Rt (return of traction current), EPI (local transmitters of information), CRO (contact ramp). ERTMS - Effective 2008 Telecommunications Measurement Systems Continuous radioelectric coverage measurement: Ground-to-train radio (analogic 400 MHz), GSM-R Measure of the GSM communication quality: GSM-R, GSM of the three public operators in France Measurement systems on IRIS antennas, including 2 GPS + 1 reservation for a satellite antenna, to come soon. 7

8 On-board operators have to validate in real time curves drawn out of raw data and calculated data provided by measurement systems They control localisation, launch complementary processes based on samples and build a database during every run IRIS 320, includes: sensors - 12 workstations m of technical floors - 20 km of optical fiber - 30 km of copper cables - 18 antennas set on train roof - 2 roof structures for catenary observation 8
