As the track layout has now changed, the existing mimic panel was out of date. It needed rebuilding anyway, so it was easier to start from scratch with a new panel. This panel also shows the state of all of the layout signals.
This uses a sandwich of 2 sheets of 3mm clear Acrylic sheet with the printed layout between them. The holes for the lights are just drilled in the rear sheet, with holes for them cut out in the paper.
The new panel fits into the same wooden frame on the windowsill that the old one used.
