At the May 2012 display in Dunedin the COMS tested a miniature video camera which could be mounted on a railway wagon. A video been made from that test footage and is provided on YouTube.
At a later Dunedin train show another video was made with a standard video camera, this one focussing on the travels of a very colourful goods train - sort of like a 'fruit salad' mix of wagon colours.
At an October 2017 COMS Sunday workshop meeting, junior member Jacob brought along a maglev toy train he had built from a kit. Here he displays the train for us.
