William Lange mentioned that he has been perusing my Roundhouse column on track planning with AF switches in the Jan-Feb 2003 issue of S Gaugian Magazine.
For those hardy few who are interested, there is an error in figure 2 of that article. At the top of the drawing, in stop zone D, I omitted the two insulating track pins or gaps that actually create stop zone D. There are three black dots, representing wire connections to the rail, near stop zone D. There should be one insulating pin or gap in the top rail just to the right of the left most black dot. There should be a second insulating pin or gap between the two dots in the top rail toward the right of stop zone D. Unfortunately, I omitted these two insulating pins or rail gaps from the drawing. Thus, stop zone D is created by these two gaps or pins which I omitted. The wire shown as running between the rails near the top of the drawing is to run power around stop zone D, so the rest of the loop does not lose power by creating a potential dead zone in it. The wire from the center one of the three black dots to the on/off switch, controls power to stop zone D itself. When the switch is on , stop zone D is powered. When the on/off switch is off, no track power gets to stop zone D and the locomotive will stop when it enters the stop zone. There have been several errors in my drawings over the years. My wiring diagram of the AF switch in 1999 had a biggie. There's another in the drawing of the 3 train automatic siding of 2000. They even printed a couple of my illustrations upside down at different times. But those are easy -- just stand on your head while you read them!
