As global rail network demand grows and historic tunnels continue to age, it is vital to detect Hidden Critical Elements (HCEs) – e.g. blind shafts and ring separation – in Rail Tunnel Subsurface Inspection (RTSSI) surveys to maintain safe and efficient network operation. Presently, no standalone RTSSI technology can swiftly nor accurately detect HCEs throughout a 3600 tunnel subsurface profile. In response, our European research project T-Vision investigates and proves the feasibility of the first air-launched, hybrid rotational ground penetrating radar system for RTSSI. We deploy the system's unique raster and helical scanning functionality in Kirton Tunnel (UK) to inspect the subsurface. Artefacts corresponding to blind shafts validate raster scanning efficacy for concealed shaft detection; whilst development scope for novel 3600 Hackle-Helix Point Clouds for RTSSI is discussed.
