    back in the old days, I make a little pulse width modulator control for my model N train's speed. The original power pack that came with the trains was unable to properly control the train at low crawl speeds, so I found this article in one of the magazines, I think it was my old Radio TV Experimenter back in the 70's. worked great.

    Do you still play with the trains ?

    They are fun.

    I like the slot cars also.
    Now they cheat and use magnets to keep them on the track.

    No Don, I don't have the trains anymore. Some I sold at a Lionel train store in NYC (I think they were O gauge?), and some I sold to buyers that had placed ads in train magazines. That was all in the 70's too. I did make out pretty good selling all that stuff.
    I have no more interest in trains; it was just a passing fancy and envy of others enjoying their trains.

    We can't live with them and we can't live without them.

    They got us by the balls.

    But that is a good thing...
