Network Rail’s Great Western Route tweeted: “Very warm weather means some speed limitations.”
A large number of rail passengers were left stranded because the “wrong heat” caused chaos on trains on among the hottest days of the season.
Greater Anglia stated: “We are extremely sorry. Speed limitations have established yourself because of high temperatures. Slower running means we can’t run as numerous trains.”
Traveller Andrew Barnard tweeted: “Wrong kind of heat Greater Anglia? It’s 2017, not 1917.”
Furious passengers required to social networking to vent their frustration as Network Rail enforced speed limitations as direct sunshine threatened to buckle rails.
