The efficient and sustainable mode of transport

More than 260,000 km of railway lines cover the European continent (source UIC). This is an asset with a replacement value of more than 1,500 billion euros.

Climate change and the necessary energy transition give rail a key role. Whether it contributes to the movement of passengers or goods, the railways embody the sustainable mobility of tomorrow.

Meeting future challenges poses several challenges.

Anticipation, a prerequisite for tomorrow’s performance. Rail networks have a large amount of equipment, which is heterogeneous and has a relatively long lifespan. Maintaining them in good condition is a budgetary and industrial challenge. Periods of chronic underinvestment are costly: the catching up of infrastructure substance is spread over several generations and the socio-economic consequences are high. It is therefore necessary to :

  • Build scenarios capturing effects of the current budgetary framework in the medium and long term, in order to properly adjust public policies.
  • Prioritise the allocation of available resources according to the value produced by the infrastructure.

Boosting innovation while controlling obsolescence. Improving the efficiency of the railways requires an effort to innovate in terms of operating principles, maintenance and renewal of infrastructure, production methods for construction sites, etc. At the same time, it is a question of ensuring the maintenance in operational condition and then the gradual eradication of equipment inherited from the past, which generally constitutes significant volumes.

Identify synergies: only a reliable projection of investment needs can identify, in time, synergies between the renewal strategies of asset families. These synergies make it possible to combine projects and thus organise real performance leaps while controlling costs.

Optimising the interaction between vehicles and the infrastructure. Physical forces generated by the movement of a vehicle on the track are extreme, the catenary (the contact wire) wears out as the pantographs pass over it, and the control and command and safety installations on the ground must communicate with those on board the trains. The systemic dependencies are thus multiple and complicate technological development.

Understanding and modelling

We design solutions that integrate the complexity, without complication, of your systems, whether it be technical, organisational or skill-based. We develop the asset management modelling and simulation platform: Eqylibr®.

Mobilising and capitalising on expertise

We enhance the expertise of your teams and perpetuate their business knowledge through digital models integrated into customised asset management tools (in the Office® suite for example) or market tools (CMMS, Eqylibr®, etc.).

Advise and transform

We provide transparent advice and create an environment conducive to the evolution of your organisation (change management) by passing on our know-how, making our digital tools available and implementing change management programmes.

The origins of IMDM

IMDM has its roots in the railway world. We have been working with national and international railway networks for over 20 years.

The beginnings of IMDM’s activity date back to the Swiss Federal Institute of Technology of Lausanne (EPFL) and its transport laboratory.

Since its creation, IMDM has continued to develop its skills in terms of business expertise, both in terms of infrastructure and railway operations, systemic analysis and ad hoc numerical modelling (the Eqylibr suite® in particular).

We carry out assignments for major players in the railway sector: audits on the state of infrastructures, second look at maintenance policies, asset management strategies (infrastructures and rolling stock), optimisation of work windows, etc.

Our lifecycle models and digital asset management platform are used in network infrastructure condition audits and in the development of infrastructure maintenance and renewal strategies. Our results are used in contract negotiations between infrastructure managers and the authorities that finance the infrastructure.
