There are careful rules about how the rail is laid and the temperature on the day it is laid of critical importance

Above 27 degrees the UK rail network collapses as the rails are outside there temperature range and risk buckling, its the critcal temperature, the air temp might be 27 but the rail would be close to 50 degress, blanket speed limits appear

The issue is with defective sleeper blocks these stresses are unrestained

Do the rails on the continent suffer from this heat problem ? Im just thinking of the yearly heat-wave in France. Or are their rails completely different altogether ?

The Platform 11 reconnaissance unit reports AMB (the Luas contractors) are on site between Red Cow and Kingswood

The Kingswood curve is the fastest curve which uses the ebilon block track

It`s also the one where the original 70KPH speed limit was reduced PDQ after opening day and which remains that way.
It`s also well worth watching how the drainage works after a period of heavy rain here......
