The Overground identity - including an orange and blue version of the familiar roundel - will only be fully introduced as each of a total of 60 stations is refurbished or built, and new rolling stock introduced. At first, you will just notice the absence of Silverlink branding, and a single new roundel, plus - from 9 November - the orange tramlines on the map.
As for the principal brand colour - orange - this finds its way into everything. 'It is a happy colour for us to use, has high visibility and can be applied consistently across all applications,' says Ferguson.
To avoid confusion, the various branches of the Overground system will not have subsidiary colours and line names in the way of the Tube - the idea is to have a destination-based system, like the DLR.The 2025 map referenced at the end of the article is this one.
