1 SNCF Infra | juin EFRTC June 11th, 2010 Bernard SCHAER Director of Contracts & Customers Services SNCF Infrastructure Branch Maintenance policies


3 SNCF Infra | juin  Rail projects in France and throughout the world  Expertise and project management  Management of investments for RFF and SNCF  Timetable management  Traffic Control  Safety and punctuality of the railway system SNCF INFRASTRUCTURE BRANCH : 3 DOMAINS MAINTENANCE & TRAVAUX 33, 000 people € 3,500 m local entities  Maintenance of the railway network  Management of investments for RFF and SNCF  Troubleshooting 24/7 CIRCULATION FERROVIAIRE 14,000 people € 950 m local entities INGENIERIES 5, 100 people € 650 m 2009 IG, INEXIA, SYSTRA

7 SNCF Infra | juin SOME OF THE ACTORS OF THE SYSTEM R.F.F. Réseau Ferré de France  Created in 1997  Owns the network  Took over €20.4b of historical SNCF debt (SNCF retained €7b)  A performance contract was signed with the State in November 2008 E.P.S.F. Etablissement Public de Sécurité Ferroviaire  Created in march 2006  European directive 2004/49  Monitors safety issues on the national railway network ARAF  Created by law in December 2009  Regulatory body for the railway sector  Should be in place before the end of 2010 ARAF Autorité de Régulation des Activités Ferroviaires  DCF still belongs to SNCF, however has some kind of an independent status  Its director is named directly by the government.  DCF works for RFF and is responsible for Traffic Control D.C.F Direction de la Circulation Ferroviaire  Maintains the network  Manages investment works on behalf of RFF  A maintenance contract is signed between SNCF and RFF since 2007 SNCF Infrastructure


9 SNCF Infra | juin The French Network Total track length UIC 1 à 4 : km ( included 3839 km HSL ) 9969 S & C ( included 754 HSL ) UIC 5 et km S & C Regional lines with passengers: km S & C without passengers: 4417 km S & C Side tracks km S & C Level-crossings Bridges Tunnels (631 km) Signal boxes 2256 Power supply Sub-stations: 535 Overhead lines 1500 V: Km (40%) V : Km (60%)

10 SNCF Infra | juin Study of EPFL 2005 The study made by EPFL in 2005 showed  Bad conditions of the network  No optimization of M/R : The share M/R was 2/3;1/3 when it was from 1/2;1/2 up to 1/3;2/3 in other europeen countries  No optimization of track possession : According to the EPFL, track possession duration was too short (1h50) and no technically and economically efficient  No optimization of traffic control : There were too much signalling boxes

11 SNCF Infra | juin What has be done so far At the end of 2005, RFF,SNCF and the French Government came to an agreement of an increasing of funding for renewal Track Bridges Sign OHL

12 SNCF Infra | juin What has be done These figures show that the track renewal program do not allow to modernize the network A model of the network’s evolution has be done Courbes d'évolution de la substance UIC 1-4 Courbes d'évolution de la substance UIC 5-6 Courbes d'évolution de la substance UIC 1-6 Without renewal With Perfomance Contract

13 SNCF Infra | juin What is going on RFF has defined his strategic vision of the network  Definition of freight corridors with high level of availability  More accurate definition of the performance of the network according to the different routes, eg:  Axel load  Speed  Gauge  Availability  Increasing of the slots for TOCs and FOCs  Decreasing of maintenance and renewal costs So SNCF has to improve the maintenance policies, in order to have more trains, more availability, as all Infra Managers do.

14 SNCF Infra | juin Maintenance policies These huge requirements lead to  An optimization of maintenance and renewal, that means an assessment of the policies on each route based on LCC  More efficiency of the renewal  Longer zones  Uniformization  Planning  The necessity of planning and reducing maintenance costs; the best way is to move from an « on condition » based maintenance to a predictive maintenance

15 SNCF Infra | juin Predictive maintenance To do that,it is necessary:  To have a good knowledge of the conditions of the network  To know the parameters which have an impact on the behaviour of the components of the infrastructure  To know the degradation’s laws of these components according to the sollicitations they have to support In order to plan the interventions

16 SNCF Infra | juin Predictive maintenance  The knowledge of the degradation’s laws,eg: Track circuits components

17 SNCF Infra | juin Tools  Development and implementation of measurement cars  IRIS 320 already in operation  Purchase of new measurement cars for conventional lines  Development and implementation of tools in order to modelize the degradation’s laws and so to define « what to do » and « when to do » eg:  Contact wire wear measurement and planning of replacement (with « Catalyse »)  Track geometry quality measurement and planning of tamping (with « TIMON »)

18 SNCF Infra | juin Contact wire wear measurement

19 SNCF Infra | juin Contact wire wear analyse CATALYSE Affichage des courbes sur différentes années de mesures avec les couleurs correspondantes.  Bleu= année 2005  Orange= année 2007  Vert= année 2009 Affichage N° support Résultats des différents calculs (% inexploitable, section moyenne des FC, point le plus bas, homogénéité,….) des différentes années de mesures Tableaux de synthèse classés par ligne  Tableau de prévision de remplacement  Tableau de suivi baguettes  Tableau de suivi des périodicités de mesures préconisées dans les référentiels Seuil d’alarme

20 SNCF Infra | juin CATALYSE Sélection des fichiers de mesures de référence et choix de la date de projection Différents traits de couleur suivant les années de mesures.  Bleu=2007  Orange=2009  Vert= Projection 2013

21 SNCF Infra | juin TIMONHSL 1

22 SNCF Infra | juin TIMONConventional Line Paris-Le Havre

23 SNCF Infra | juin Remote control  Development and implementation of remote control for level crossings Signalling and S & C in 3 Supervision Centers (Paris, Lyon,Pagny/Moselle) Curve of translation of a switch

24 SNCF Infra | juin Maintenance methods Implementation of new methods of maintenance for a higher durability of the interventions eg:  Tamping in BAS  Grinding  Tamping and grinding

25 SNCF Infra | juin Optimization Maintenance/Renewal Y(T) = Coûts cumulés d’entretien de 0 à la date T X = Coûts de régénération à la date 0 Y max (T)/T Niveau de saturation de «nuit» Niveau de saturation de «jour» Y min (T)/T To X/T T (âge de renouvellement)

26 SNCF Infra | juin Models of maintenance costs Maintenance costs are modelized according to track possession and distances between stations
