A bit of reverse engineering is what is happening today.
The N Scale layout at the club is capable of DC or DCC use and the old DC controllers are starting to get a bit iffy they reckon. So we need to build a new one or two.
Easy you say? But sadly the fella that built them is no longer with us and I can't find any documentation at the club for how they were built. So I am pulling one apart to see how it was built and of what it was built. This way I might be able to find some diagrams etc on the web or be able to nut it out myself and build the new ones we need.
So after a few hours I've almost documented it - physically that is. The next part will be to draw a proper circuit diagram...
