    Any idea how to pick power from metal wheelsets to feed a FRED ?
    I have schematics to stabilize the power to feed the LED's, but have no idea what to use to pick the current from the wheelsets.

    They sell copper pickups that go right to the tracks, or you can go to the wheels like a loco. You want real light pressure in either case,

    Phosphor bronze wire was the old standard for wipers. I think MicroMark still sells it. I found it was easier to install 4 AAA rechargable batteries in HO equipment. If you use a CMOS flasher circuit (not a 555 or 556) they will run 2-3 weeks between charges 24/7. I use the self contained T-1 LED flashers and they also run 2 to 3 weeks 24/7 on 4 AAA NiMH batteries. Put a 220 ohm resistor in series with the battery/LED and charge the batteries with a 6VDC wall pack. I drilled a hole in the floors and installed standard plugs to charge them. If you are doing N you can get NIMH button batteries, but they would not last as long between charges. FRED
