Compare Scales
Deciding which scale to model in can be a difficult task for the beginner and experienced model maker. This page aims to provide some basic data about each scale including links to specialist societies and mailing lists. The class 66 diesel locomotive is available in a number of different scales and as examples become available to me I will include photographs to illustrate the differences between the scales.
