Re: Caboose Trucks


Works equally well AC or DC. No flicker as the capacitor stores enough power to keep the markers lit for several minutes, even if off the track. Therefore dirty track, dead frogs, or less that perfect truck wipers are not a problem.

I've not tried to put a switch on mine. The resistor in line with the LED can be adjusted to get the brightness you desire based on your ambient light.

Does this circuit work with either/both DC or DCC?
How difficult to add a magnetic switch to turn the markers
