SNCF Infrastructure

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

7 SNCF Infra | juin 2010

Created in march 2006

Created by law in

December 2009

European directive

2004/49

Regulatory body for the railway sector

Monitors safety issues on the national railway network

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

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

10 SNCF Infra | juin 2010

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

Without renewal

With Perfomance Contract

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.

13 SNCF Infra | juin 2010

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

14 SNCF Infra | juin 2010

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

15 SNCF Infra | juin 2010

Predictive maintenance

The knowledge of the degradation’s laws,eg:

Track circuits components

16 SNCF Infra | juin 2010

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 »)
