Here’s the kicker: the UK has been dealing with hot railways since the Victorian era. But in 2026, the system still reacts to 30°C like it’s being asked to solve a Rubik’s Cube. Greater Anglia and c2c have both issued warnings that journeys will take “significantly longer” – which is rail-speak for “pack a tent and some snacks.”
One poor soul on Twitter (or X, or whatever it’s called now) reported a 45-minute delay on a c2c train from Shoeburyness because the line’s “expansion joints got scared.” That’s right – even the metal underneath you is getting stage fright. Nobody is immune, not even the train itself.
And let’s not forget the air conditioning. On a normal day, train AC is a polite suggestion. On a scorcher, it becomes a cruel joke. Passengers have reported “sauna conditions” on Greater Anglia services, where the windows fog up and people start eyeing the emergency hammer for ventilation, not escape.

The Science (and the Sweat)
Here’s a surprising fact: steel railway tracks can get 20°C hotter than the air temperature. So if it’s 32°C outside, the rail is basically a frying pan. This heat causes something called “buckling,” where the track decides it wants to become a gentle zigzag. That’s a hard no for trains doing 70mph.
For the love of all that is holy, why don’t they just paint the tracks white? They’ve tried, but apparently it costs a fortune and the paint wears off. So instead, we get Twitter meltdowns and articles like this. The irony is that Switzerland manages fine in alpine heat. But let’s be honest – we’re British. We panic if the tea is lukewarm.
Greater Anglia’s official advice? “Allow extra time for your journey.” That’s like telling a fish to “just swim around the hook.” Genius. They also recommend checking before you travel, which is a nice way of saying “our system is held together by prayers and WD-40.”

What Can You Actually Do?
First, don’t take the 8am express. That’s when the sun is at its sassiest. Second, bring a battery-powered fan and a sense of humour. You’ll need both. I met a guy at Stratford station who brought a camp chair and a book – he wasn’t even mad, he was prepared.
Third, remember: c2c and Greater Anglia are not evil. They’re just fighting a war against physics, and physics is winning. The wires expand, the tracks buckle, and your boss is sending passive-aggressive Slack messages. It’s a beautiful, chaotic mess that only Britain can produce.
So the next time you’re stuck on a c2c train near Upminster, sweating through your shirt, don’t curse the driver. Curse the sun. It’s been doing this for 4.6 billion years, and it’s not about to change for your morning commute.
In the meantime, may your water bottle be cold, your phone charged, and your delay only 47 minutes. Cheers, Britain. We’ll get through this – probably after autumn.
