Daily Mail does physics!

This from the Daily Mail...

Now it's the wrong kind of sun! Train companies tell drivers to slow down because 'hot weather is heating up tracks'...

Network Rail has imposed a 20mph speed restrictions across a stretch of line in the West Country because of the effect the heatwave could have on the tracks.

The curb on speed - called heat speeds - has been imposed between Bathampton Junction and Sydney Garden near Bath...

A spokesperson for Network Rail said: 'We have over the weekend renewed that small section of track and therefore its heat tolerance level is lower than the norm."

Quite so. But on the plus side...

Whilst this tolerance level is relatively low, it compares favourably with the railway's towards the Mail.
