Novel Solution Cuts Cardiff Bridge Wiring Cost

The title of this post is the same as an article in the May 2018 Edition of Modern Railways.

This is the first paragraph.

Network Rail has applied an insulating coating to the underside of a bridge in Cardiff to protect against flashover from the future Overhead Line Equipment (OLE). It also intends to fit surge arresters at the bridge to prevent any sudden spikes in voltage overcoming the protection provided by the coating.

Network Rail reckon that the solution will save about £10million on this bridge alone, as it avoids the need for an expensive rebuild of the bridge.

Could wider applications of solutions like this, reduce the cost of electrification?
