Blue Warning Sign – Temporary Speed Restrictions

The use of Blue WARNING Sign is mandated for use from 1 July 2019 replacing the yellow warning signs.

The change to the blue WARNING sign will visually separate it from the CAUTION sign and allow Drivers and Track Vehicle Operators to respond appropriately to the sign type.

Flashing lights must be used on temporary speed throughout Sydney Trains Network to provide better visual indications of the signs during darkness or low visibility.

A SafeTrack has been published on RailSafe with more details.
