Hope you enjoy this video update: Video update Oct Meanwhile progress marches on. I have been working on Broughton some more and have installed all but 4 PMG Relays as point motors. I am currently wiring up the control panel. I have a dedicated point power supply in the control room ready to hook up tot he wore Andrew Gallacher ran for me last week. |

Recently I allowed some signals to go in at Gracton, acting as Point indicators for now. It was mentioned by a regular operator
that point indication could be useful, thunking more signals could be of use. But signals canot be seen fron all directions.
So I remembered the bit I wrote many years ago, shown on the right. SoI am thinking of using the tortoise
motors ability to use LED directly wired in series to show indication. In this case bicolor LED's
can show which way a point is.

| So my latest idea is to put a LED indicator whre each point is, sort of a tiny panel. I already have a paper sign at every mainline DCC controlled point. I'll make the sign become a panel with either one LED or two. | ||

The diagram on the left uses one LED, red shows reverse, green the normal indication. Saves on LED's.
The diagram shows the idea on the right. Every point is shown on the graphic. this version shows a LEd for the normal and reverse indication. this version means I have two Bicolor LED's in use, so we get a red/green indication which reverses when the point is thrown. |

|
So here's how they work, side by side as a point is thrown. Wonder what is better ? The two LED one cycles between red and green, the green shown the road. The single LED shows red for reverse, and green for normal.
