On 27 June 1947 36.6°C was recorded at Ukkel and that is a record that has stood for over seventy years.
Brussels wasn’t the hottest part of the country. In the Kempen District temperatures in excess of 40°C were recorded.
In early afternoon a new Belgian record was set in Kleine Brogel (Limburg). The 40.2°C record set in Angleur Liège on Wednesday was improved when 40.6°C was recorded at the air base.
The intense heat triggered problems across the rail netowrk. A Thalys train got stuck between Mechelen and Brussels due to problems with overhead cabling. As a result only two out of four tracks between Antwerp and Brussels were available leading to delays. Elsewhere too trains ground to a halt outside stations stranding passengers. Problems have been reported between Kortrijk and Oudenaarde.
On the coast services of the coastal tram were halted due to problems with overhead cabling.
