The railway travels along a famously picturesque route along the south coast, with sheer sedimentary cliffs on one side, and the open ocean on the other. The project aims to improve this infrastructure by re-aligning the tracks and ultimately creating more space on the coastline. This space will allow for the installation of rockfall protection, will increase beach retention, and provide amenities to the public such as walking and cycling routes.
Robertson Geo Televiewers were deployed to increase their geological dataset where core sample recovery was impeded. Understanding groundwater conditions by running the NMR (nuclear magnetic resistivity) was also a priority, as with electrical measurements from the Focussed Electric and Electric Log probes.
Other tools deployed included the 3-Arm Caliper, Triple Sonic, and the Temperature/Conductivity probe which provided important data on issues such as saltwater incursion into these coastal aquifers.
