I recently saw a layout where he had red and green led lights in the roadbed next to the switch points to indicate switch position. I am just in the thinking stage about wiring but I am considering using the short plastic dwarf signals to indicate switch position. Green for the main, yellow for the siding and the red could be used for the next block whenever my electrical gets to that point. My reason for thinking about doing it this way is just so the operator knows before he is on top of it which way the turnout is thrown. There will be only walkaround.

I'm getting ready to run my main DCC buss for my TOMA module. After watching videos and reading a book on layout out wiring, some guys twist the buss wires and some do not. Larry Puckett in his book "Wiring Your Model Railroad" shows photos with twisted buss wires, but doesn't say it is necessary in the text.

Ha anyone found or created an enclosure for the NCE USB board?

It does not seem a good idea to simply screw it to the fascia with the circuit exposed.

Just wondering what folks use on their layouts for providing power to switch machines, DCC accessories (reversers, controllers,...) structure lighting, etc.  Do you prefer wall-warts or larger power supplies?  How beefy a supply do you prefer (obviously related to layout size and number/type of powered devices)?  Do you use any of the many computer power supplies?  eBay or other sources?  Anyone use the power supplies various DCC vendors sell for their systems for other than powering their boosters/command stations?
