Who Are We?

SCLE is a high-tech company specialized in IT and electronics for Energy and Rail.

A human, technical and technological adventure over 50 years

Our company has its roots in energy—what better source of inspiration to reinvent ourselves? 

Since its inception, our business has branched out from electrical networks to rail networks, with catenaries providing the obvious linchpin between the two.

Moving forward, reinventing ourselves, breaking new ground—one step at a time—takes time. Innovation takes time. Luckily, we have it.

At SCLE, sustainability is key; reliability a mindset.

That means we’re here to last in terms of:

• The products we deliver

• The people who work for us

• The relationships we forge with our partner-customers

We can see far into the future, allowing us to take the time to do the job well and to build relationships with customers on solid foundations

Highly qualified in electrical energy and rail transport

SCLE is created in Toulouse …

While the SNCF celebrated its 31 birthday, André Coudé du Foresto created SCLE to renovate and modernize the rail network in the  French South-West.

… and ERJI Agence in Marseille

Jean Robert founded ERJI the same year. The first products marketed were underwater exploration cameras going to a depth of -6,000 m!


Manufacture and integration of classic substation chassis

With the boom of telecoms, the need for relay racks is felt and the opportunity for SCLE to manufacture and integrate classic substation racks.


Design of the first SCLE product: the RH

With the boom in electronics, Jean-François Revel put equipment in tune by creating the RH.


Acquisition of ERJI

ERJI joins SCLE to advance in the growing sectors of energy and rail


Start of the PCCN offer

The IT revolution is underway, workstations are going digital: SCLE designs the first PCCN equipment on the market.

SCLE Milestones

SNCF creation

Creation and modernization, renovation of the railway network


Telecom boom

The development of telecoms initiates the economic transformation of the 1980s in the world


Electronics boom

Electronics is developing in industry and in particular energy and railways, which find ingenious applications for it.


Command-control digitalization

The first partially distributed command-control systems in electrical substations were deployed in France from the early 2000s


Digital substation

From the merger of the electrical and computer network emerges a new generation of connected and digitalized transformer stations


Digital signaling

Railway signaling is also beginning its digital revolution, driven by the advent of ERTMS in Europe


The turning point of the energy transition

Energy storage and new nuclear technologies are the key to the energy transition, to counter the intermittency of renewable energies and offer the expected flexibility to the existing network.
