The NZ120 module standards are an interesting example of localization and adaptation using availbable materials to model New Zealand local prototypes.
The Automationz webpage explains, “NZ120 is the common name (within New Zealand Model Railway Guild circles) for a scale more accurately referred to as TTn3.5, that is 1:120 scale (or 1/10″ to the foot) modelling of a 3’6″ prototype (the gauge of all of New Zealand’s rail lines).” This page also has a thorough review and comparision of other popular module standards and how NZ120 came to be.
The New Zealand Model Railway Guild publishes the NZModel Railway Journal and has links to plan sets, FAQ, suppliers, photo gallery and events listings. The sample article, One Thing or Another, is a sample article showing the flavor of New Zealand railway modeling, including wonderful railway model photos.
The Chosen Scale Cooperative has their 1999-2002 newsletter index online and provide additional details regarding NZ120 cost, model availability and techniques. The Cooperative also has a brief “What is NZ120” introduction available.
The Railmodel Electronics and NZ120 page as links to photo galleries, NZ120 module standards, and thorough discussion of the NZ120 design concept.
