The soaring temperatures have led to hundreds of school closures, or partial closures, across London and southern England. <\/p>\n
Transport for London warned passengers that “very high temperatures may cause disruption to some Tube and rail services, particularly the London Overground and Elizabeth line”. <\/p>\n
These two services share rail infrastructure with Network Rail, which said the hot weather could affect overhead lines, the tracks and signalling equipment. <\/p>\n
Network Rail urged passengers to “only travel if absolutely necessary to, from or within red warning zones” and to stay hydrated.<\/p>\n
