RTSA NZ Chapter Cleaning the Otira Tunnel Presentation by Neil Mason

Recently Neil Mason from Vitruvius presented on a large project that he helped drive, there was some international interest in the project which was Cleaning the Otira Tunnel so he kindly agreed to present again under live and webinar conditions. The project was very complicated and involved a large range of disciplines not often included in rail work, the presentation was very interesting and is well worth a watch.
