stability are observed to reduce the risk of incident in accordance with Safety
Management Standard STD/0075/TEC Hot Weather Precautions for Track Stability,
namely :-

all trains to 120 km/h
Air Temperature 40°C and above - On timber sleepered track, restrict
all trains to 40 km/h (#)
- On concrete sleepered track, restrict

(#) Steel sleepered track and timber sleepered track with interspersed steel sleepers
shall be regarded as equivalent to timber sleepered track for track stability.
Speed restrictions may also be put in place after maintenance activities in accordance
with QR Safety Standards.
The extent of restriction will depend upon the type of maintenance activity and risk of
track misalignments.
Force Majeure Events will also see the imposition of speed restrictions, the extent and
severity of the restrictions being dependent on the event.
