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

Without renewal
With Perfomance Contract

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

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

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


The knowledge of the degradation’s laws,eg:
Track circuits components
16 SNCF Infra | juin 2010


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 »)
