I spend probably 40 minutes a day crammed cheek to sweaty jowl with other London commuters—some of them drunks, farters, and shovers—in a swiftly moving cylinder hundreds of feet underground. It’s usually hot, and despite the fact that we are Tetrised in there, all of us are trying desperately to pretend that we are completely alone. Rarely do I give thanks for the experience, but this year marks the 155th anniversary of the London Underground, that efficient marvel of public transport.

On January 9, 1863, the world’s first-ever underground railway train, steam-operated, pulled out of Paddington Station, and rumbled 3.5 miles down the tubular tunnel to Farringdon Station. The line, which was financed by Metropolitan Railway, was an instant success: Approximately 40,000 people lined up for the novelty of riding a train underground. Within six months, 26,000 people were riding the train each day.

By 1884, there were more than 800 trains in operation in what was called the Inner Circle, a circular line that enclosed central London and that is now just the Circle Line. And now, with more than five times that number of trains operating and millions of people safely and swiftly reaching their destinations every day, the London Underground is truly a modern miracle of efficient transport. Here are 15 impressive facts and figures you might not have known about the London Tube.

1. THE MAJORITY OF THE LONDON UNDERGROUND IS NOT UNDERGROUND.

The entire London Underground network is approximately 249 miles long, employing more than 4100 trains, and linking 270 stations. But only about 45 percent of those miles are underground.

2. EACH TRAIN TRAVELS ABOUT 114,500 MILES A YEAR.

Each Tube train travels an average of 114,500 miles a year, or 4.6 times around the world. The longest distance between adjacent stations is approximately 3.9 miles, from Chesham to Chalfont & Latimer. The shortest distance is about 984 feet, between Leicester Square and Covent Garden on the Picadilly Line (and since Covent Garden is usually mobbed, you’re better off getting off at Leicester Square and walking).

3. MORE THAN 1 BILLION JOURNEYS ARE MADE EACH YEAR.

Each year, about 1.3 billion journeys are made on the London Underground. The busiest station in the network is Waterloo, which sees about 100.3 million passengers per year; the least used is Roding Valley.

4. HALF A MILLION MICE CALL THE UNDERGROUND HOME.

An estimated 500,000 mice live in the tunnels, but they’re not the only pests—the mosquitoes that live in the Tube are of a different and somewhat more vicious species than their aboveground cousins. Called Culex pipiens molestus, they’re supposedly known for their voracious appetites.

5. THERE ARE SOME GHOSTS REPORTEDLY LIVING DOWN THERE, TOO.

The London Underground is also supposedly home to a group of subterranean Londoners, who, just like the Mole People of New York’s Subway, took to the tunnels and mutated. The Tube is also reportedly home to a host of ghostly apparitions, including the Faceless Woman of Beacontree Station, the Toothy Man of Channelsea Depot, and the Screaming Spectre of Farringdon Station.

6. THE AVERAGE LONDONER SPENDS 11.5 DAYS OF EACH YEAR ON THE TUBE.

The average Londoner spends an average of about 11.5 days each year on the Underground—5.2 of those days in the Underground’s underground tunnels. (What’s unknown is how many hours of those days are spent stopped underground, waiting for a signal failure to be resolved, for another train to move along, or for whatever bit of rubbish that has been thrown on the tracks at the station ahead of you to be cleared.)

7. THE FASTEST TRAINS TRAVEL AT SPEEDS OF OVER 60 MILES PER HOUR.

The fastest line is the Metropolitan, where trains can reach speeds of more than 60 miles per hour, but the average speed of a London Underground train is only around 20.5 miles per hour.

8. THE DEEPEST STATION IS NEARLY 200 FEET BELOW STREET LEVEL.

The deepest Underground station is Hampstead, on the Northern Line, which is located about 192 feet below street level. There’s an elevator, of course, but also an emergency spiral staircase featuring more than 320 steps, in case of emergency (or a fit of exercise mania).

9. IN 1969, QUEEN ELIZABETH TOOK CONTROL OF THE VICTORIA LINE.

In 1969, Queen Elizabeth II commemorated the opening of the Victoria Line by driving one of the new trains from Green Park to Oxford Circus. It was her second ride ever on a London Underground train, the first being when she was 13 and accompanied by her sister and governess. Presumably her stint as Tube driver was without incident, as eight years later, the Queen was again allowed in the cab of a Picadilly Line train when she presided over the opening of the line’s extension.

10. THE FIRST ESCALATOR WAS A MISERABLE FAILURE.

The Underground’s first real escalator was built in 1911 at Earl’s Court, but four years before that, a spiral escalator was installed at Holloway Road Station. It didn’t last very long—in fact, it only lasted for a day of testing and never actually saw public use. Its remains are held at the London Transport Museum’s Depot, which is only open to the public a few times per year.

11. THE LONGEST ESCALATOR IS NEARLY 200 FEET LONG.

The longest escalator at any Underground station is the 197-foot-long moving stair at Angel, in Islington, on the Northern line.

12. PEOPLE HAVE LEFT A LOT OF WEIRD THINGS ON THE TRAINS.

Among the strangest things left on the Underground and collected by the Lost Property Office: a jar of bull semen; an outboard motor; three dead bats in a container; a vasectomy kit; a harpoon gun, which may have gone with the 14-foot-long boat; a stuffed eagle; breast implants; false teeth and a surprising number of prosthetic limbs; a four-foot-tall Mickey Mouse; six full-sized mannequins; and an urn containing a dead man’s ashes, which was reunited with his brother five years after it was lost.

13. JERRY SPRINGER WAS BORN AT HIGHGATE STATION.

Politician-turned-trash talk show host Jerry Springer was born at Highgate Station on the Northern Line on February 13, 1944, when his mother sought shelter during a Luftwaffe raid during World War II.

14. MANY PEOPLE USED TUBE STATIONS AS AIR RAID SHELTERS DURING WORLD WAR II, EVEN THOUGH THE GOVERNMENT BANNED THE PRACTICE.

Speaking of air raids: At the start of the London Blitz, Germany’s nightly bombing raids on the British capital in September 1939, the government banned people from using the Tube stations as air raid shelters, claiming that the stations should be reserved only for transport. People got around the ban by simply buying a ticket and refusing to leave the platform. A month later, the government realized that the ban was unenforceable at best and cruel at worst, and gave the go-ahead for stations to be used as shelters.

By the end of the war, sheltering in the Underground had became so regular that a ticketing scheme was introduced to keep people from panicking at the queues, and more than 22,000 bunk beds were installed in stations across the system to provide places for them to sleep.

15. ITS ICONIC MAP WAS INSPIRED BY A CIRCUIT BOARD.

The London Underground’s iconic map, which bears no relationship to actual topographical or geographical features, was designed in 1933 by Harry Beck. Beck, an engineering draftsman who worked in the London Underground’s signals office, was supposedly inspired by electronic circuit boards, and saw ways of tidying up the lines. But the department rejected the initial proposal, claiming it was too radical, and Beck was paid a paltry sum, less than $15, for his work. Two years and some modifications later, however, the Underground adopted the map and has used it ever since.

6 Strange Maritime Mysteries

The oceans cover over 70 percent of our planet, so it's little wonder that their seemingly impenetrable depths have provided a series of fascinating mysteries, from missing ships to eerie monsters. Below are six mysteries of the deep—some of which scientists think they've at least partly explained, while others remain truly puzzling.

  1. The Mary Celeste

On December 5, 1872, the crew of the British ship the Dei Gratia spotted a vessel bobbing about 400 miles off the coast of the Azores. They approached the Mary Celeste to offer help, but after boarding the ship were shocked to find it completely unmanned. The crew had disappeared without a trace, their belongings still stowed in their quarters, six months' worth of food and drink untouched, and the valuable cargo of industrial alcohol still mostly in place. The only clues were three and a half feet of water in the hold, a missing lifeboat, and a dismantled pump. It was the beginning of an enduring mystery concerning what happened to the crew, and why they abandoned a seemingly sea-worthy vessel.

Numerous theories have been suggested, including by crime writer Arthur Conan Doyle, who penned a short story in 1884 suggesting the crew had fallen victim to an ex-slave intent on revenge. A more recent theory has pointed the finger at rough seas and the broken pump, arguing they forced the captain to issue an order to abandon ship. Since the missing crew have never been traced, it seems unlikely that there will ever be a satisfying answer to the enigma.

  1. The Yonaguni Monument

In 1986, a diver looking for a good spot to watch hammerhead sharks off the coast of the Ryukyu Islands in Japan came across an extraordinary underwater landscape. The area reportedly looked like an ancient submerged village, with steps, holes, and triangles seemingly carved into the rocks. Ever since it was first discovered, controversy has surrounded the site that's become known as the Yonaguni Monument, with some researchers—such as marine geologist Masaaki Kimura—arguing it is a clearly manmade environment, perhaps a city thousands of years old and sunk in one of the earthquakes that plagues the region. Others believe it's a natural geological phenomenon reflecting the stratigraphy (layers) of sandstone in an area with tectonic activity. The area is open to scuba divers, so the really curious can strap on air tanks and decide for themselves.

  1. The Bermuda Triangle

The Bermuda Triangle has probably spawned more wild theories, column inches, and online discussion than any other ocean mystery—more than 50 ships and 20 aircraft are said to have vanished there. Although the triangle has never officially been defined, by some accounts it covers at least 500,000 square miles and lies between Bermuda, Florida, and Puerto Rico.

The mystery first caught the public imagination in December 1945 when Flight 19, consisting of five U.S. Navy TBM Avenger torpedo bombers and their 14 crewmembers, were lost without a trace during a routine training operation in the area. Interest was further piqued when it was later reported that one of the search-and-rescue planes dispatched to find the missing team had also disappeared. Articles and books such as Charles Berlitz’s The Bermuda Triangle, first published in 1974 and having since sold over 20 million copies in 30 languages, have served to keep the mystery alive, providing potential theories both natural and supernatural. Scientists—and world-renowned insurers Lloyd’s of London—have attempted to debunk the myth of the Bermuda Triangle, offering evidence that the rate of disappearance in the vast and busy triangle is no higher than other comparable shipping lanes, but such is the power of a good story that this is one story that seems likely to continue to fascinate.

  1. The Kraken

For hundreds of years, sailors told tales of an enormous sea creature with huge tentacles known as the Kraken. Stories around the mythical kraken first started appearing in Scandinavia in the 12th century, and in 1555 Swedish cartographer Olaus Magnus provided an account of a sea creature with “sharp and long Horns round about, like a Tree root up by the Roots: They are ten or twelve cubits long, very black, and with huge eyes.” The stories persisted, often mentioning a creature so large it resembled an island. In his 1755 book The Natural History of Norway, Danish historian Erik Ludvigsen Pontoppidan described the kraken as “incontestably the largest Sea monster in the world."

Scientists have proposed that these stories might derive from sightings of giant squid (Architeuthis dux), although evidence for an even larger, yet extremely elusive, colossal squid (Mesonychoteuthis hamiltoni) has also come to light. The colossal squid is found in the deepest part of the Southern Ocean surrounding Antarctica, and is thought to be up to 46 feet long and 1100 pounds. The problem is that the animal is so rare very few specimens have been found intact, and no live specimen has ever been observed, which means that estimating its exact size is difficult. Researchers have also noticed that sperm whales have been observed with large scars, and have suggested that these could be the result of violent encounters with the colossal squid, which is known to have sharp rotating hooks on the ends of their tentacles.

  1. The Treasure of the Merchant Royal

The remains of the Merchant Royal are known as one of the richest shipwrecks ever. The ship set sail from the New World in 1641 laden with 100,000 pounds of gold, 400 Mexican silver bars, and thousands of precious gems—in total, a haul thought to be worth $1.3 billion today. The ship got caught in a storm and was thought to have gone down somewhere off the coast of Cornwall, England. The lost wreck became known as the “el Dorado of the seas” due to the enormous value of its cargo, and over the years numerous treasure hunters have searched fruitlessly for its final resting place, which remains undiscovered. In 2019 fishermen snagged what is thought to be the anchor from the Merchant Royal, but to date the dangerous conditions and extreme depths at which the wreck is thought to lie have meant it has remained unclaimed.

  1. Attack of the Sea Foam

In December 2011, residents of Cleveleys, England, awoke to what appeared to be a soft blanket of snow. But as locals ventured out into the streets it soon became clear that this was no snowstorm, but instead something far more puzzling. Trees, cars, roads, and houses were all wrapped in a thick, white layer of foam. The Environment Agency were quickly deployed to take samples of the sea foam, since residents were understandably concerned as to the origin of the strange, gloopy substance, fearing it might be caused by pollutants.

The dramatic images of the foam-soaked town soon had journalists flocking to the region to investigate the phenomena, but as quickly as it appeared the foam disappeared, leaving behind only a salty residue. Scientists analyzing the foam confirmed it was not caused by detergents, and instead suspected that it was caused by a rare combination of decomposing algae out at sea and strong winds, which whipped up the viscous foam and blew it into land. The phenomena has apparently occurred at other times before and since, and researchers are now working to try and understand the exceptional conditions that cause it to form so that residents can be warned when another thick blanket is set to descend.

Bonus: The Bloop—Mystery Solved

Over the years, the oceans have produced a number of eerie and often unexplained sounds. In 1997, researchers from NOAA listening for underwater volcanic activity using hydrophones (underwater microphones) noticed an extremely loud, powerful series of noises in the Pacific Ocean. The unusual din excited researchers, who soon named it “The Bloop” in reference to its unique sound.

Theories abounded as to the origin of the bloop—secret military facility, reverberations from a ship’s engine, or an enormous sea creature. The most fanciful suggestion stem from H. P. Lovecraft fans who noticed that the noise came from an area off South America where the sci-fi writer’s fictional sunken city of R’lyeh was supposed to be. They proposed that the bloop might have originated from Lovecraft’s “dead but dreaming” sea creature, Cthulhu. In 2005, however, scientists found that the mysterious sound was in fact the noise made by an icequake—or an iceberg shearing off from a glacier.

10 Clever Stranger Things Season 3 Easter Eggs You Might Have Missed

Warning: This story includes spoilers for all aired episodes of Stranger Things.

After waiting nearly two years for the latest season of Stranger Things, most fans couldn’t help but binge all eight episodes in a row. But now that we know how it all went down, with Billy Hargrove being taken over by the Mind Flayer and Jim Hopper’s tragic (maybe) death, it's time for us to reprocess the season ... and rewatch it all over again.

While giving the season a second watch, keep an eye out for all the clever Easter eggs sprinkled into each episode, including several references to classic 1980s movies, earlier Stranger Things episodes, and unexpected connections we had never imagined were possible.

1. Peter Gabriel could be hinting at a major plot twist.

Arguably the most heartbreaking scene in Stranger Things history came in the final episode of season 3, “The Battle of Starcourt,” when Eleven reads the scrapped letter Hopper wrote for her and Mike. Viewers at home cried along with Millie Bobby Brown's character as she prepared for life without her “dad,” but one element in the scene might be a hint that Hopper isn’t really dead.

The song that starts playing just as Eleven finishes up reading the letter is Peter Gabriel’s cover of David Bowie’s “Heroes,” which is the same rendition of the song that played in the season 1 episode “Holly, Jolly,” when it was believed that Will had been killed. Of course, he turned out to be very much alive, meaning the same could (hopefully) happen for Hopper.

2. Jim Hopper is channeling Martin Brody.

Stranger Things has never shied away from paying homage to classic movies. And Redditor LucasLeArtist noticed that one of Hopper's season 3 lines was a direct quote from Jaws. When Hopper is about to leave Enzo’s after Joyce stands him up, he’s told he can’t take the alcohol with him, to which he drunkenly responds, “I can do anything I want, I’m chief of police.” This mimics a scene in Jaws where Chief Brody said the same line before taking a swig of his drink.

3. Murray Bauman’s phone number is real.

One of the more eccentric characters in Stranger Things, Murray Bauman, turned out to be extremely helpful this season, as he served as translator for Hopper and the Russian scientist Alexei. In one scene, Murray’s phone number is shown—and it turns out that it's a working phone number ... which does indeed belong to Murray. As CNET reported, when you dial 618-625-8313, you get a lengthy, and hilarious, answering machine message from the character.

4. Billy Hargrove’s nod to Stand By Me.

While Billy Hargrove surprisingly turned into a character you felt sorry for by the end of season 3, his scenes in the first episode proved he was still just as much of a bully as he was in season 2. One example of this is when he’s lifeguarding and yells at a kid for running by the pool. Billy calls him a “lard-ass,” which doesn’t just remind you of how mean of a person he is, but is also a borrowed line from Rob Reiner's classic 1986 film Stand By Me. As IndieWire pointed out, that particular insult was famously used in the movie during the scene in which Gordie tells his friends a memorable story about a pie-eating contest.

5. Dustin Henderson is crushing on Phoebe Cates.

When Dustin returns to Hawkins from camp, he shocks everyone with the reveal that he now has a girlfriend. Of course, the first reaction from his friends (Steve included) is that she isn’t real. Dustin keeps the story going, however, telling everyone that her name is Suzy and that she's better looking than Phoebe Cates—as in the actress best known for her role in 1982’s Fast Times at Ridgemont High. In the season’s final episode, we learn that Suzy is indeed real. And when Robin is trying to get Steve a job at the video store, he falls into a cardboard cutout of Cates as Linda Barrett (her Fast Times character) before stopping to admire it.

6. Dustin and Robin recreated a scene from 1992's Sneakers.

A Twitter user pointed out an unexpected callback to the 1992 River Phoenix film Sneakers, as Dustin and Robin recreate one of its scenes when getting the “complete blueprints” of the Starcourt Mall. It's almost word-for-word, with the only difference being that in Sneakers, they’re looking at the Playtronics Corporate Headquarters.

7. Eleven visits the house from A Nightmare on Elm Street.

During Eleven’s scariest venture into the Void this season, she tries to find the missing lifeguard Heather. As she approaches Heather's home, the red door is reminiscent of the house that belonged to Nancy Thompson’s family in 1984’s A Nightmare on Elm Street. A Twitter user claimed the number on both doors was the same, but Stranger Things changed it by one number, as Heather lives at 1438. We’re not sure if they had to change it because of legal matters or if was just a coincidence—but in a show full of horror movie references, the similarity would seem a little too coincidental.

8. Steve Harrington can't keep his Michael J. Fox projects straight.

When Dustin, Erica, Steve, and Robin manage to escape the Russians in the seventh episode, “The Bite,” they end up in the movie theater at the mall, which is showing Back to the Future (1985). Steve and Robin soon leave, and while very high—and trying to analyze what they just watched—Robin hilariously says she’s pretty sure “that mom was trying to bang her son,” referring to Marty McFly and his mom, Lorraine. A confused Steve replies, “Wait, wait, the hot chick was Alex P. Keaton’s mom?” Alex P. Keaton, of course, was the name of Michael J. Fox’s character in the hit NBC series Family Ties, not Back to the Future.

9. "Weird" Al Yankovic's Reality Bites link.

In episode 2, “The Mall Rats,” Winona Ryder's Joyce ends up ditching Hopper to go find the kids’ science teacher Mr. Clarke, only to find him jamming out to "Weird" Al Yankovic’s parody song “My Bologna.” A Twitter user pointed out that this could be a nod to 1994’s Reality Bites, which features a memorable scene of Ryder dancing to the original song, “My Sharona.” Ethan Hawke is also in the scene, who is the real-life dad of Maya Hawke, who plays Robin in Stranger Things.

10. The post-credits scene that hints at Hopper's survival.

Perhaps the most important detail in the entire season comes during the post-credits scene, which includes another major hint that Hopper is still alive. Viewers are taken to the Russian base, where prisoners are being fed to the Demogorgon. One soldier then says, “No, not the American,” before moving on to the next person held captive. Fans are convinced the American would have to be Hopper, although there are plenty of theories floating around about other Americans that character could be. Now we’ll just have to wait until season 4, which has not been announced yet, to know who it is for sure.
