Over the past couple of weeks I've been installing the turnout motors and controls. For the interchange at Wesso there are three different possible routes. The three drawings below illustrate the three conditions. The SP traffic is shown in red and the WP traffic is shown in orange.
Looking at these drawings I realized that the turnouts could be operated in pairs and only require two control outputs. I wanted to use push buttons this time and wanted an indication of which of the three conditions was active.
