The proposed network follows the existing suburban rail services and provides 220 kilometres of safe, car free cycle routes and can be accessed at over 200 entrance points. Almost six million people live within the catchment area of the proposed network, half of whom live and work within 10 minutes of a SkyCycle entrance. Each route can accommodate 12,000 cyclists per hour and will improve journey times by up to 29 minutes. As London’s railway lines were originally built for steam trains, they follow contours that naturally reduce the amount of energy expended and so avoid steep gradients. Associated benefits include the regeneration of the typically low value, often underutilised industrial sites next to railway lines by offering direct, accessible transport connections; vertically layering the city to create new social spaces and amenities on these cycling high streets; and the integration of automated goods delivery networks.
