Chainages
Note the chainages provided are based on Appendix B of the 2016 Jacobs NZ report, which has a scale measured from Penrose to Mangere Bridge, and a second scale measured from the end of line at the Airport. I filled in the gaps by measuring the lengths between them and converting from the latter to the former, probably accurate to within 10m or so. Anothersignalman (talk) 22:05, 10 May 2024 (UTC)
