I was wondering if anybody had ever tried using a light switch and a dimmer switch (push on/off type) as a controller setup for their layout. What I had in mind was the dimmer switch would turn the setup on, and control the speed, while the light switch would control the direction. Would such a setup even be possible?If the dimmer is based on a thyristor chopper circuit as is usual then
it's not going to be much use. You can build a power supply out of a
simple variable resistor and switch setup but that tends to be very power

I think I have everything I need to get started with Rokuhan track EXCEPT, insulated rail joiners for DC blocks. I looked at the Rokuhan website, and the only insulated joiner shown insulates both rails for a reversing loop.

Cut it with a dremel or similar. It's then often a good idea to put a
tiny spec of something in the gap. It's not needed for the wheel guidance
(for a thin slit anyway) but it avoids getting nasty problems over time
if the rail moves with heating and cooling and touches again.
Or just use a double isolating track and feed power always to both sides
of the one rail.
