    Sigh :(
    if only I could read those things.

    Just goes to show you, no matter how smart you are there's always something new to learn.

    Mikey,
    thanks for posting the circuit site. I will use the rectifier bridge using schotsky diodes regulate the DCC wave form thereby allowing me to put bi-color LED's across the rails to indicate the polarity (train direction). This is especially useful when the track is broken into various circuits to allow for multidirectional use such as reverse loops, 'Y' or ramps between track levels.
    Take care, Jim

    Does that mean - that you could make "signals" out of them too?? :)

    I'm glad it'll help you! thanks!!

    Converting a pulsed DCC waveform into a polarized DCvoltage level would allow for both light signals (bi-levvel LED mounted into a signal block) or a semiphore signal. Ciould also be used to indicate track polarity (direction) especially when the track is out of sight (tunnels or behind obstacles). I'm away from my layout
    but when I return I'll build a rectifier and power a bi-color LED.
    Radio Shack's Cat# 276-1653 has 25 schotsky diodes for $2.49.
    Take care, Jim
