Network Rail has ramped up work on its Access for All programme – part of the government’s Inclusive Transport Strategy – through the use of digital twin technology. The rail operator is currently making all rail transport and stations fully accessible, with the drone topographical surveys used to provide accurate, quality-assured data for four stations. Full civils design support for the upgrade of the four station structures was provided by Arcadis, while tech firm Sensat and construction company Osborne completed the surveys. Surveys were completed at Barnes, Isleworth, Stoneleigh and Wandsworth Town. Sensat captured 0.14km2 of photogrammetric data in two days, including buildings, stairs, canopies, bridge structures, permanent ways and signals to support requirements for retro-fitting lifts and ramps across these stations.
