Re: Large scale wiring/ code 332 rail
toggle quoted messageShow quoted text
I have a large scale garden railroad, but it is only 20' X 30' and is actually smaller than my basement Sn3/Sn2/S layout, which is my main layout. I could look at the DCC waveform on it with a scope or a Fluke ScopeMeter, but it is buried in snow right now.
The large scale layout is my "relaxed" layout, so I used Code 332 sectional track (mostly LGB) with a simple trackplan. Note to small scalers, although it uses sectional track, I have straight sections that are about 4' long, so it really doesn't have any more joints than a similar sized small scale layout using flextrack. Some comments on wiring. When I first started wiring it, I soldered #12 AWG feeders onto the rail. I found my resistance soldering unit at maximum output (300 watt) worked the best for me; even better than a small butane torch. I tried several methods except for a propane torch. I didn't want to melt plastic ties and the wire insulation. I since added the split jaw rail clamps to all the rail joints and found that using a fork terminal under the head of one of the clamp bolts seems to work fine for a power connection, and is a lot easier than soldering.
I ran my main wires in PVC conduit, that roughly follows the mainline. The feeder wires are just buried in the stone/dirt. The power source is in an enclosed porch that is adjacent to the railroad. There is a PVC conduit from the porch that tees into the layout conduit for the power. All my turnouts are manual.
I haven't had any real issues with using track power with the brass rail. I just need to keep the track clean of leaves, squashed bugs, etc.
