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

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

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.


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


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


Predictive maintenance

The knowledge of the degradation’s laws,eg:Track circuits components


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 »)
