SNCF Infrastructure

R.F.F.Réseau Ferré de France

E.P.S.F.Etablissement Public de Sécurité Ferroviaire

  • 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

  • Created in march 2006

  • European directive 2004/49

  • Monitors safety issues on the national railway network

  • Created by law in December 2009

  • Regulatory body for the railway sector

  • Should be in place before the end of 2010

  • 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

  • Maintains the network

  • Manages investment works on behalf of RFF

  • A maintenance contract is signed between SNCF and RFF since 2007

Total track length

  • UIC 1 à 4 : 19885 km ( included 3839 km HSL )

    9969 S & C ( included 754 HSL )

  • UIC 5 et 6 13803 km - 7621 S & C

    Regional lines

  • with passengers : 11723 km - 4113 S & C

  • without passengers: 4417 km - 2171 S & C

    Side tracks 14949 km - 46177 S & C

  • Power supply

  • Sub-stations: 535

  • Overhead lines

    • 1500 V: 12 547 Km (40%)

    • 25 000 V :19 098 Km (60%)

Study of epfl 2005
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

At the end of 2005, RFF,SNCF and the French Government came to an agreement of an increasing of funding for renewal

A model of the network’s evolution has be done

These figures show that the track renewal program do not allow to modernize the network

What is going on
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
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
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 maintenance1
Predictive maintenance

  • The knowledge of the degradation’s laws,eg:

    Track circuits components


Tools
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 »)
