Train cables melt and roads buckle in Northwest's 46C heatwave

The soaring record breaking heatwave in the Pacific Northwest which has caused train wires to melt and roads to crack is expected to continue, according to the national weather authority.

The National Weather Service has urged people to stay safe as the worrying trend is expected to continue as temperatures cause damage to transport links. This includes the asphalt on the highway, which expanded and ruptured due to the hot weather.

Train cables have also melted as the temperatures smash previous records. In places such as Portland in Oregon it hit 44C , beating the previous all time high of 42C.
