After a couple of weeks of boring and tedious work with wiring and stuff, I could finally run the first train on the newly built Grimstad station module. And everything seems to work like it should - strangely enough...
Controlled chaos. I've never done the wiring on a module all by myself, and I was surprised to experience how much work it really is.
Every single length of tracks has it's own set of wires to ensure maximum reliability. Rail joiners have a tendency to stop working after a couple of years, but now this shouldn't be a problem.
Yours truly driving the first test-train :)
I still have to install the turntable and the track leading to it. That will be tonight's task.
