The signal designer can be used to synthesise a signalling design given an infrastructure containing tracks but no signals, and given a set of auto-dispatch specifications (see Dispatch).

The set of auto dispatches to be used as the basis for the synthesis are shown in the left part of the window, and can be deactivated if you do not wish for the design to satisfy this auto dispatch plan.

The right part of the window contains the designs that are output from the synthesis procedure, along with their score. Select a design from the list to add it to the current infrastructure.
