Adding motion to a static display can really add to its impact. Over the years LEGO have brought out a number of different systems to do this. This tutorial looks at the Mindstorms system before Power Functions came out, as well as how they integrate with 9v Railway systems.

The tutorial will show how cranes can be controlled to move automatically, lifting and moving loads, as well as using light sensors to control trains to stop and start at stations.

As most veteran 9-Volt Train fans will attestify, the cables supplying power to your trains, lighting and other things eventually start breaking down after a few years of use. Rather than throwing them out and trying to replace them, you can repair them or create custom length cables.

This tutorial will give you all you need to know to keep your 9volt system wiring going for years to come.
