197707 – Detering – Centralised Traffic Control and Power Signalling – Rockhampton-Gladstone – Part 2: Circuit Design

The circuit design principles adopted for the scheme, were based upon standardised field interlocking circuits for each form of control system, i.e. whether controlled by individual switch panel, centralised traffic control, or by remote route setting control.

All relays used are of the BRB 930 series and are generally of the normal electro-magnetic type with no magnetic latching or sticking feature.

Diagrams setting out in block schematic form the circuit principle adopted for each system, are shown in Figures 1, 2 and 3.
