Chiltern Railways has already cancelled more than half of its normal timetable, as a red extreme heat warning for Wednesday and Thursday prompts Network Rail to impose speed restrictions across most mainlines from London, with no rail replacement buses. Temperatures are forecast to reach 37C widely and possibly 40C in the worst-affected areas, risking buckled rails, sagging overhead wires and signalling failures. LNER also strongly recommends against travel on those days, while the Midland mainline faces additional limits following the fatal Bedford collision.
