On my control panels and any dwarf signals I have used, a Green indicator = "Closed" (Through the turnout route) and Red = "Thrown" (Divergent route).  In recent posts I have seen, some use the opposite color indicator, Red = Closed, Green = Thrown.  Just curious if there is a generally accepted "standard" for Closed and Thrown color indictors.....

I have an MRC Controlmaster 20 walkaround power supply that went on the fritz yesterday.  It has been a great unit for at least 12 years now.  I had an engine derail, and when I set the engine back on, it took off at high speed.  I am unable to control speed, momentum or braking with the throttle.  Only thing I can do is change direction.  As soon as turn on the power, whichever engine I use just takes off.  All of the switches  are properly set.  Something must have shorted out.

While cleaning out one section of our club layout room, we found two bundles of Railcraft code 250 rail.  Does anyone have a clue what this bundles would be worth and who would use them?  Code 250 seems too big for O Scale, but too small for G Scale.  Any ideas?

What I'd like to do is to take the output of a Digitrax SE8C card that is already driving a signal, and 'duplicate' that on a second signal.  Unfortunately, the output is not strong enough to drive 2 LEDs.  What I'm looking for is a 'circuit' that will allow me to drive a second LED/signal.

I found plenty when I searched for 'LED repeater circuit', but I'm not savvy when it comes to electronics.  Most of it didn't seem applicable.
