What goes into manufacturing a model railway loco
How a great model is made
It is sometimes very difficult to appreciate the work that goes into producing a model railway product. As a collector and dealer, it can be frustrating to have to wait for completely new products to be manufactured so it is a real priviledge when manufacturers draw aside the curtain and reveal the processes and production stages of a model.
Roco have begun publishing films on the manufacturing process. Although they are in German, they are facinating to watch:
This is a series of films on the new OBB Rh1046 model:
The first film shows the research into the subject as well as production developement using computer modelling. The production engineers have to take into account the variations in the locomotive design as they were modified throughout their service life. The engineers also have to translate a locomotive into model form - great attention to detail is required as all of the individual components must fit together perfectly without having to be individually re-worked. Every part of the model is explored before a single physical part is made:

The second film shows the construction of the tools.
The main body is the most complex part - the 3D shape needs a complex sliding mold to be manufactured so that the highly detailed, hard plastic body shell may be formed and released from the tool witout damage - The injection molding tool is constructed from 350 parts just to make the body shell. In the film you see the cab being CNC milled from a block of copper. This copper master is then used to cut into a hard steel block using the spark erosion process:
