Hello 21C1, In the video it's a modified GM UF just made on some matrix board to see if it's any different from the original version. You can see the three circuits here: https://www.scottpages.net/ReviewOfControllers.html

Also a 'taster' here: https://ogaugemicro.blogspot.com/p/controllers.html with a comparison of the above and the Brian Tilbury pulsed/feedback controller using similar components. Both have the same superb control and are from the 1970's.

If you or anyone else would like my PDF which assumes no knowledge of electronics, please send me a nice message it does take time to author the PDF's I send out and now I ignore one line phone speak demands.

Cheers - Jim

The carpenters flat pencil is excellent for the job, I just never got round to replacing the one I started with. I've just found one amongst the stuff I cleared out from my stepson's static mobile home. Thanks H..., you actually took my advice.

Hello all,

Slippage? Certainly not!

Back in the 1980's, applying graphite to rail heads was all the rage.

Until it was found that it got spread around a layout and clogged up all rolling stock wheels with 'gunk' which in turn, causes lots of wobbly running.

Been there, got the T-short. Not worth the effort. There comes a point where one has to accept that when track is bent, pitted and unlevel etc, it is life-expired and should be replaced.
