The five mined underground stations in central London - Bond Street, Tottenham Court Road, Farringdon, Liverpool Street and Whitechapel – set the foundations for the common design components.
The geometries defined by the tunnel engineering inside these stations are celebrated and become one of the most distinguishable features of these stations. The use of sprayed concrete lining has led to curved junctions and spaces that are larger in scale compared to existing London Underground assets. These bigger spaces, with separate exits at opposite ends of platforms into brand new ticket halls, will accommodate future passenger growth.
Glass-fibre reinforced concrete is used to clad the structural tunnel lining, leaving smooth, sweeping, curved edges that promote easy navigation and reduce blind spots for passengers. In each of the new underground stations, full height platform edge screens will provide lighting, wayfinding and service information while also separating passengers from the operating trains.
Consistent design, incorporating enhanced lighting and signage strategies, will clear the platforms and passageways of clutter and create a quality passenger experience as they move through the long platforms.
Many of the features synonymous with a railway - such as seating, signage, communications and fire safety equipment, handrails, screens, escalators and lifts – use a set of common parts that employ a clean design language and robust materials to create a consistent and familiar feel for the line. All of these consistent elements have been engineered to be tough and long-lasting.
Adapting common design across the route
The common design components were developed to be applicable and adaptable across the entire line. These components include a carefully considered palette of robust materials, signage, lighting and seating.
In addition, a structural layout that lends itself to intuitive wayfinding has been implemented.
