Tracks buckle in the Uk at 50 degrees so why do we have speed restrictions under V/Line at 33?

As air temperatures hit 28C (82F) the track's temperature got significantly higher.

If the ambient temperature reached 50C in the UK (or anywhere for that matter) it would be more than rails that would bend.

Well the headline got your attention x31, but you should have read the article. Air Temperature was only 28C.

Quote from the article below.

"As air temperatures hit 28C (82F) the track's temperature got significantly higher, Network Rail said."

And they also have speed restrictions in place as reported further down :

"Speed restrictions have been in place all week on the route from London Waterloo to New Malden due to the scorching temperatures, causing delays to services."

This would not be ambient air temperature but absorbed in full sunlight.
I watched our Track Superviser take the Rails temperature and while it was only what I would describe as a pleasantly warm day(30C?), the rail read 53C.
He said this was not unusual but what concerned him was those areas where the line was shaded like coming out of a tunnel or through a cutting as this disparity could cause problems.

Funny that we describe 30C as pleasantly warm and in Europe they're carting people off to hospital with heat-stroke. I suppose we'd get hypothermia on one of their "pleasantly cool" winter days.

I visited Belgium and Germany one April in their Spring, but what we would classify as mid Winter with Max temps around 10.

Also, in Italy, I noticed that rails had been painted white in some places - a method of trying to reflect heat maybe?

I think i remember getting an email about Aurizon trialling painting rail in certain places.

Network Rail in the UK is apparantly painting rails in places now.

Hardly new, I remember almost 50 years ago to the day going to a destressing in northern England and we couldn't do the work as the rail temperature was 50 deg C. So we just sat and watched a procession of polished steam engines heading off to collect their trains on the last big weekend before the steam farewell special. Managing stress free temperature is a critical operation. The weakness here is the widespread use of dog spikes in main lines and poor track structure with limited lateral restraint.

Been In London on a 35 degree day.

Yes people were complaining, but life still went on (lots of people just head to the waterways)
