The initiative for the development of the dynamic speed indicator (DSI) came about as a result of drivers in QR. The idea of the DSI evolved through a number of workshops in QR. The workshops involved representatives of drivers and operational staff statewide, signalling and personnel.
The main reasons for the changes in signalling philosophy in QR were:
To improve information for drivers as it was found that improving information to drivers is often overlooked in the haste to install signalling.
To improve train handling;
To ensure the signalling aspects in QR were consistent.
