The interventions data was provided by KiwiRail and routes are created using Rail Centreline wherever possible. New Oakleigh to Marsden Point route is created using the designated route for Marsden point line published by KiwiRail(https://www.kiwirail.co.nz/our-network/our-regions/northland-rail-rejuvenation/ ). City Rail Link route is created using the projected City Rail Link route map (https://www.cityraillink.co.nz/route-map). Care has been taken to represent the segments as close to the original routes but the actual routes can be different to the segments shown in the map and these segments should only be taken as indicative.
