Track side fires
What could buckled rails cause and what do drivers need to do when rails are buckled?

How to mitigate the risk of fog?
Reduce speed
Assume signals are at stop if cannot be seen
Make frequent use of whistle
Is it recommended to use high beams in fog?
No
What is the speed of the train with
water BELOW the rail head that is not flowing?
15km/h
What is the speed of the train when there is
water over the railhead
Water flowing across the track?
Do not proceed
What is the speed with
water OVER the rail head (below 75mm) after it has been inspected?
5km/h
What is the speed of the train
water over the railhead is now subsiding and is now below the rail head and not flowing
15 km/h cautiously if not obstructed (until inspected)
