Aecom has produced a graphene arch using additive manufacturing techniques. It believes the method could reduce the time and cost of installing digital signalling systems and transform the digitisation of transport networks.
The company’s CNCTArch is designed to drive down the costs associated with installing digital signalling systems on transport networks. Using a graphene arch that sits over rail tracks eliminates the need to attach new digital equipment to existing infrastructure.
Graphene is famously super-light and super-strong. The 4.5-metre high, lightweight arch is being tested on outdoor track at Network Rail’s workforce development centre in Bristol.
