UK hits all-time temperature record — Analysis

Numerous people have been affected by heat-related negligence, even though the National Health Service warns about inevitable heat-related deaths. 

Five people, mostly teenagers, have died in open water since Saturday.

Transport chaos was caused by high temperatures. Both railway operators and motoring group RAC called on passengers and motorists to avoid traveling unless it is “Absolutely necessary.” For those who still decide to travel, warnings have been issued. The RAC stated that they expect a 20% rise in breakdowns.

Network Rail has introduced speed limitations, saying that due to temporary speed limits the journeys will take significantly longer, with a “Probability high” of cancellations, delays and last-minute alterations.

Network Rail announced its heat wave record in addition to the many travel warnings posted Monday and Tuesday.

Not only are iron rails at risk from extreme temperatures, but also other structures. It is possible to see the Hammersmith Bridge’s 135-year old chains wrapped in silver insulation foil, which should prevent overheating. In summer, the chains must be kept below 13C. Safety engineers will close the bridge to pedestrians and cyclists if any reach 18C. It was closed for motor traffic until recent repairs.
