@Rogerret Metal likes to expand quite significantly when its hot. The expanson of the tracks causes the tracks to bend in all different direction thus trains run far far slower on really hot days if at all
CWR tracks work well in hot weather but give really pure performance in cold
-
There are a number of places that have high speed trains operating without restrictions in high temperatures..........India, France, Italy, Spain to name but a few. We never had restrictions here in the days of short butted rail, they have come with CWR which was supposed to be a cure all. The Japanese use expansion joints not unlike point blades to solve the problem

Thank you for the quick answer!
I did some research on the Internet and found a .pdf document from V/Line, that briefly explains the situation.
But the text part "Basically, steel expands in extreme heat, so V/Line trains run at slower speeds to be safe. This is standard operating procedure for railway companies around the world." is not completely correct.
There are many railways that do not impose heat speed restrictions.
Sweden is one and they have a much wider temperature span.

This was shot in the suburban area so no high speed there. All lines are affected on hot days.
-
What was the reason for this restriction?
I have heard that speed restrictions are imposed during hot days.
Are all lines affected by this measure or only those not having CWR (Continuous Welded Rails)?

that train has a nice face.

I think these should be used in QLD, as QR's aging ICE series trains fail so much.(QLDmatt has a vid where ICE 158 'malfunctions' )

Not too many vehicles get past them in the 160km/h sections. But you are correct RFR is a joke.
