Who Are We?

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

A human, technical and technological adventure spanning 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
