EcoDesign CCD shoe

Mersen’s teams keep innovating and proposing recyclable solutions.

Today’s requirements for technical performance cannot go without environmental performance. Let’s take the example of a 3rd rail shoe, used to transmit power from the 3rd rail to the railcar system traction unit. The only wear part is the carbon strip; all the other components would in most cases not need to be replaced. However, as the strip is currently assembled by welding, the whole shoe is scrapped after use, which is a waste of resources and money.

Mersen have pioneered and patented a 3rd rail CCD shoe called « EcoDesign ». The concept is to reuse all the metal components (carriers and bolts) with the replacement of the carbon wear strip only. Using a new assembly method, Mersen takes one step forward on the road to be Eco-responsible in eradicating the need of lead brazing.

In 2013 the Mersen “EcoDesign” concept won the Innovation Trophy at the SIFER rail industry trade show.
