I operate in DC/Analog control (haven't made the jump to DCC). For anyone who has wired a layout like this, you know how painstaking it truly is. As the layout changed, so did the panels. There are currently four panels that control the railroad.
The first panel shows the whole layout minus the industry sidings. A red LED signified a dead block and a green LED represents a live block. At a turnout, red means that the train will diverge from the current track and green means that the train will continue to go straight. In the case of this panel, “Main 3” and “Main 3 Sub” as well as “Platform 2” and “Platform 3” are special. If the line is green, that means that both the block is live AND the switches are aligned properly. Red means that there is no power to the block and the switches are aligned to the opposite track.
The next panel includes the industry lines. The same pattern for the LEDs on the above panel was used on this panel. It represents both the lumber mill on the left and the oil refinery on the right.
