  • Otago Central Railway [62A]: Kilometre Posts on the Rail Trail

    The Otago Central Railway maps incorporate full mile post indications for the entire length. The positions have been derived from various information in the chainage books for the line and by estimation these positions could have an error of plus or minus 100 metres. Recently I have obtained additional information from Geoff Mackley that has…

  • Otago Central Railway [61C]: Finishing Maps – Cromwell-Alexandra 1

    Well I decided that I needed to check everything starting from Cromwell so that is where I have been busy for the last few days. As it happens I had two sets of aerial photo mosaics from Cromwell, and they didn’t match up, so I re-rendered both the full and part sets of retro images…

  • Otago Central Railway [61B]: Finishing Maps – Clyde 1

    So while I am working on the Addington mosaic, that is a pretty slow process with a lot of downtime waiting for Gimp to resize images, the best part is with another computer doing only that and nothing else, I can carry on with maps on my main computer. And in actuality that is a…

  • Main North Line [11A]: Addington, etc

    Having completed sorting through aerial photos of the MNL and now having a complete set, the next task is to start doing stuff with the photos. The first thing that will happen is I will do a set of historical maps for Addington, as that is where the MNL starts. When I first started looking…

  • Main North Line [10]: Aerial Photography

    Most of the mapwork over the past few days has been with MNL aerial photography which has to be downloaded and then sorted through to pick up just the photos I want. This is a slow process because of the download limit of 3.5 GB per download from the Linz website and the number of…

  • Otago Central Railway [61A]: Finishing Maps

    There has been quite a bit of progress with maps since the last blog post. I am just not blogging as often lately, but I will start to pick that up again.  I have mapped the entire TGR line with all the detail available including full and half km posts and other details I can…

  • Otago Central Railway [60C]: Ranfurly to Wingatui 3

    Today I finished and submitted Part 3 of the Otago Central series to NZRO. I believe this edition will appear in print in about a month. The illustrations which have been submitted appear below. There was a minor crisis when I typed up the reference list and found it came to something like 1500 words.…

  • Otago Central Railway [60B]: Wingatui to Ranfurly 2

    Well it has been a few days since the last posting, however as of today I am commencing to write Part 3. Part 2 came out last week in the Observer and my chief regret is that the maps weren’t actually completed for Part 2. This only needed Auripo map to be finished before the…

  • Otago Central Railway [60A]: Wingatui to Ranfurly 1

    Wingatui to Ranfurly is Part 3 of the article series on the Otago Central Railway. This means I have to have all the knowledge about the line along this route finalised. In addition this part will contain more information about the private sidings of Alexandra.  Right now I am using the recently obtained chainage book…

  • Otago Central Railway [59A]: Taieri Estate Sidings

    As of now I am putting together the aerials needed to show three generations of siding development at Taieri Estate. Using four images from DCC GIS I am joining these together to make a 1947 image of the aerodrome, which had a siding used to load fuel until the late 1950s. Right now as can…
